Handling Energized Products

General Safety Practices

Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.

Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts.

Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective ground terminal. If a ground lug is provided on the product, it should be connected to the protective ground at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in grounded racks and cabinets.

Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.

Connecting AC Mains

Make sure that the electrical installation complies with local codes.

Always connect the AC plug to a wall socket with a protective ground.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.

In cases when the power distribution system is IT type, the switch must disconnect both poles simultaneously.

Connecting DC Power

Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded.

Due to the high current capability of DC power systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards.

DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel.

Make sure that the DC power supply is electrically isolated from any AC source and that the installation complies with the local codes.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position.

A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

If the DC power supply is floating, the switch must disconnect both poles simultaneously.

Connecting Data and Telecommunications Cables

Data and telecommunication interfaces are classified according to their safety status.

The following table lists the status of several standard interfaces. If the status of a given port differs from the standard one, a notice will be given in the manual.

Ports Safety Status

V.11, V.28, V.35, V.36, RS-530, X.21, 10 BaseT, 100 BaseT, Unbalanced E1, E2, E3, STM, DS-2, DS-3, S-Interface ISDN, Analog voice E&M

SELV Safety Extra Low Voltage:

Ports which do not present a safety hazard. Usually up to 30 VAC or 60 VDC.

xDSL (without feeding voltage), Balanced E1, T1, Sub E1/T1

TNV-1 Telecommunication Network Voltage-1:

Ports whose normal operating voltage is within the limits of SELV, on which overvoltages from telecommunications networks are possible.

FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are not possible. These ports are not permitted to be directly connected to external telephone and data lines.

FXO (Foreign Exchange Office), xDSL (with feeding voltage), U-Interface ISDN

TNV-3 Telecommunication Network Voltage-3:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are possible.

Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a qualified safety engineer.

Always make sure that the equipment is grounded before connecting telecommunication cables. Do not disconnect the ground connection before disconnecting all telecommunications cables.

Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables. Extra caution should be exercised during thunderstorms.

When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The grounding and bonding of the ground connections should comply with the local codes.

The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk,

there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.

Pour réduire les risques s’incendie, utiliser seulement des conducteurs de télécommunications 26 AWG ou de section supérieure.

Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such cases, a notice will be given in the installation instructions.

Do not attempt to tamper with any carrier-provided equipment or connection hardware.

Electromagnetic Compatibility (EMC)

The equipment is designed and approved to comply with the electromagnetic regulations of major regulatory bodies. The following instructions may enhance the performance of the equipment and will provide better protection against excessive emission and better immunity against disturbances.

A good ground connection is essential. When installing the equipment in a rack, make sure to remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an external grounding lug is provided, connect it to the ground bus using braided wire as short as possible.

The equipment is designed to comply with EMC requirements when connecting it with unshielded twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on certain cables. In such cases, special instructions are provided in the manual.

Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.

The compliance of the equipment with the regulations for conducted emission on the data lines is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss (LCL).

Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary protection against surges on the data lines. Primary protectors should be provided in the building installation.

The equipment is designed to provide adequate protection against electro-static discharge (ESD). However, it is good working practice to use caution when connecting cables terminated with plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching ground or wear an ESD preventive wrist strap.

Encapsulation Encapsulating data is a technique used by layered protocols in which a low level protocol accepts a message from a higher level protocol, then places it in the data portion of the lower-level frame. The logistics of encapsulation require that packets traveling over a physical network contain a sequence of headers.

Ethernet A local area network (LAN) technology which has extended into the wide area networks. Ethernet operates at many speeds, including data rates of 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet), 1,000 Mbps (Gigabit Ethernet), 10 Gbps, 40 Gbps, and 100 Gbps.

Ethernet OAM Ethernet operation, administration and maintenance (OAM) are a set of standardized protocols for measuring and controlling network performance. There are two layers of Ethernet OAM: Service OAM (provides end-to-end connectivity fault management per customer service instance, even in multi-operator networks) and Link or Segment OAM (detailed monitoring and troubleshooting of an individual physical or emulated link).

Flow Control A congestion control mechanism that results in an ATM system implementing flow control.

Frame A logical grouping of information sent as a link-layer unit over a transmission medium. The terms packet, datagram, segment, and message are also used to describe logical information groupings.

Framing At the physical and data link layers of the OSI model, bits are fit into units called frames. Frames contain source and destination information, flags to designate the start and end of the frame, plus information about the integrity of the frame. All other information, such as network protocols and the actual payload of data, is encapsulated in a packet, which is encapsulated in the frame.

Full Duplex A circuit or device permitting transmission in two directions (sending and receiving) at the same time.

FXO (Foreign Exchange Office)

A voice interface, emulating a PBX extension, as it appears to the CO (Central Office) for connecting a PBX extension to a multiplexer.

FXS (Foreign Exchange Subscriber)

A voice interface, emulating the extension interface of a PBX (or subscriber interface of a CO) for connecting a regular telephone set to a multiplexer.

Gateway Gateways are points of entrance and exit from a communications network. Viewed as a physical entity, a gateway is that node that translates between two otherwise incompatible networks or network segments. Gateways perform code and protocol conversion to facilitate traffic between data highways of differing architecture.

Half Duplex A circuit or device capable of transmitting in two directions, but not at the same time.

Impedance The combined effect of resistance, inductance and capacitance on a transmitted signal. Impedance varies at different frequencies.

Interface A shared boundary, defined by common physical interconnection characteristics, signal characteristics, and meanings of exchanged signals.

IP Address Also known as an Internet address. A unique string of numbers that identifies a computer or device on a TCP/IP network. The format of an IP address is a 32-bit numeric address written as four numbers from 0 to 255, separated by periods (for example, 1.0.255.123).

Jitter The deviation of a transmission signal in time or phase. It can introduce errors and loss of synchronization in high speed synchronous communications.

Laser A device that transmits an extremely narrow and coherent beam of electromagnetic energy in the visible light spectrum. Used as a light source for fiber optic transmission (generally more expensive, shorter lived, single mode only, for greater distances than LED).

Loopback A type of diagnostic test in which the transmitted signal is returned to the sending device after passing through all or part of a communications link or network.

Manager An application that receives Simple Network Management Protocol (SNMP) information from an agent. An agent and manager share a database of information, called the Management Information Base

(MIB). An agent can use a message called a traps-PDU to send unsolicited information to the manager. A manager that uses the RADview MIB can query the RAD device, set parameters, sound alarms when certain conditions appear, and perform other administrative tasks.

Multiplexer At one end of a communications link, a device that combines several lower speed transmission channels into a single high speed channel. A multiplexer at the other end reverses the process. Sometimes called a mux. See Bit Interleaving/Multiplexing.

Network (1) An interconnected group of nodes. (2) A series of points, nodes, or stations connected by communications channels; the collection of equipment through which connections are made between data stations.

Node A point of interconnection to a network.

Packet An ordered group of data and control signals transmitted through a network, as a subset of a larger message.

parameters Parameters are often called arguments, and the two words are used interchangeably. However, some computer languages such as C define argument to mean actual parameter (i.e., the value), and parameter to mean formal parameter. In RAD CLI, parameter means formal parameter, not value.

Payload The 48-byte segment of the ATM cell containing user data. Any adaptation of user data via the AAL will take place within the payload.

Physical Layer Layer 1 of the OSI model. The layer concerned with electrical, mechanical, and handshaking procedures over the interface connecting a device to the transmission medium.

Port The physical interface to a computer or multiplexer, for connection of terminals and modems.

Prioritization Also called CoS (class of service), classifies traffic into categories such as high, medium, and low. The lower the priority, the more “drop eligible” is a packet. When the network gets busy, prioritization ensures critical or high-rated traffic is passed first, and packets from the lowest categories may be dropped.

Protocol A formal set of conventions governing the formatting and relative timing of message exchange between two communicating systems.

RADIUS (Remote Authentication Dial-In User Service)

An authentication, authorization and accounting protocol for applications such as network access or IP mobility. Many network services require the presentation of security credentials (such as a username and password or security certificate) in order to connect to the network. Before access to the network is granted, this information is passed to a network access server (NAS) device over the link-layer protocol, then to a RADIUS server over the RADIUS protocol. The RADIUS server checks that the information is correct using authentication schemes like PAP, CHAP or EAP.

Router An interconnection device that connects individual LANs. Unlike bridges, which logically connect at OSI Layer 2, routers provide logical paths at OSI Layer 3. Like bridges, remote sites can be connected using routers over dedicated or switched lines to create WANs.

Routing The process of selecting the most efficient circuit path for a message.

Serial Transmission A common mode of transmission, where the character bits are sent sequentially one at a time instead of in parallel.

SFP (Small Form-factor Pluggable)

A compact optical transceiver used in optical communications. It interfaces a network device (a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. It is a popular industry format.

Single Mode Describing an optical wave-guide or fiber that is designed to propagate light of only a single wavelength (typically 5-10 microns in diameter).

Synchronous Transmission

Transmission in which data bits are sent at a fixed rate, with the transmitter and receiver synchronized.

T1 A digital transmission link with a capacity of 1.544 Mbps used in North America. Typically channelized into 24 DS0s, each capable of carrying a single voice conversation or data stream. Uses two pairs of twisted pair wires.

Telnet The virtual terminal protocol in the Internet suite of protocols. It lets users on one host access another host and work as terminal users of that remote host. Instead of dialing into the computer, the user connects to it over the Internet using Telnet. When issuing a Telnet session, it connects to the Telnet host and logs in. The connection enables the user to work with the remote machine as though a terminal was connected to it.

VLAN-Aware A device that is doing the Layer 2 bridging according to the VLAN tag in addition to the standard bridging parameters. A VLAN-aware device will not strip or add any VLAN header.

VLAN Stacking A technique that lets carriers offer multiple virtual LANs over a single circuit. In essence, the carrier creates an Ethernet virtual private network to tunnel customer VLANs across its WAN; this helps avoid name conflicts among customers of service providers who connect to the carrier. Stacking works by assigning two VLAN IDs to each frame header. One is a "backbone" VLAN ID used by the service provider; the other one has up to 4,096 unique 802.1Q VLAN tags.

Introduction

1.1 Overview

ETX-201 is a carrier-class demarcation device that separates the private LAN and the operator’s network. ETX-201 offers flexible network and user port combinations. The network ports support link aggregation according to IEEE 802.3ad requirements. The user ports accept traffic, providing different port-based services. At the physical level, ETX-201 supports autonegotiation, flow control and fault propagation. The unit can be managed via a local terminal port, or via one of its Ethernet ports (inband or out-of-band management). ETX-201 includes a DHCP client utility that obtains the IP address, IP mask and default gateway values, and defines a network manager automatically.

Device Options

Several versions of the unit are available, offering different combinations of Ethernet ports and enclosure types.

• Ethernet ports:

Port 1 and 2: any standard Fast or Gigabit Ethernet fiber optic SFP

Port 3: any standard Fast Ethernet fiber optic SFP or built-in 10/100BaseT

Ports 4–6: built-in 10/100BaseT.

• Enclosure type: plastic box (regular unit) or metal box (temperature-hardened version).

Applications

In a typical application ETX-201 provides Ethernet access to a packet-switched network (Figure 1-1) or next generation SDH/SONET network (Figure 1-2) over a fiber optic local loop.

Features

Network Interface

ETX-201 includes two network ports. The network ports use industry-standard Fast or Gigabit SFP (Small Form-Factor Pluggable) hot-swappable optical transceivers. Refer to the SFP data sheet for the complete list of the SFPs supported by ETX-201.

User Interface

ETX-201 user interfaces terminate in up to four built-in RJ-45 ports or into SFP-based fiber optic ports. The RJ-45 user ports support autonegotiation and flow control.

Link Redundancy

The unit supports link aggregation (1+1) based on 802.3ad requirements.

Dual homing technology (1:1) allows ETX-201 to be connected to two different upstream devices.

Bridge

ETX-201 features an internal bridge, operating in VLAN aware and VLAN unaware modes. VLAN stacking can be used for traffic separation between different users or services, by defining a Service VLAN ID per customer or service. When VLAN stacking is used, a Service VLAN tag is added to the user traffic and removed from network traffic. Both Service VLAN ID and Service VLAN priority can be defined.

Installation and Operation Manual Chapter 1 Introduction

ETX-201 Ver. 3.6 Overview 1-3

QoS

ETX-201 supports traffic prioritization and rate limitation.

Traffic Classification and Prioritization

ETX-201 provides four priority queues for each user port. The traffic can be classified and mapped into the priority queues according to the VLAN priority, DSCP, IP TOS or per port basis.

Rate Limitation

ETX-201 supports an egress rate limitation per port (network and user) and ingress rate limitation per user port.

Fault Propagation

The unit provides the network-to-user fault propagation mechanism. When the fault propagation is enabled, the user port shuts itself down when a link failure is detected at the network port.

Management

Setup, monitoring and diagnostics tests can be performed using one of the following methods:

• Out-of-band via ASCII terminal connected to the V.24/RS-232 DCE control port

• Network management using Telnet, terminal Web-based application, or RADview-EMS, RAD’s SNMP-based management system

Inband management via one of the Ethernet ports

Out-of-band management via the last user port configured as a dedicated management port.

ETX-201 can be managed via a third-party SNMP-based NMS, using SNMPv3.

ConfiguRAD

ConfiguRAD is a user-friendly Web-based terminal management system serving for remote device configuration and maintenance. It is embedded into ETX-201 and provided at no extra cost. ConfiguRAD can be run from any standard Web browser.

Inband Management

For the inband management, the host of ETX-201 can be configured to the tagged or untagged operation:

• When the host tagging is enabled, the host packets receive a VLAN tag, creating a dedicated management VLAN.

• When tagging is disabled, no traffic separation is performed and management packets can be forwarded to the user port.


1-4 Overview ETX-201 Ver. 3.6

Security

The following security protocols are provided by ETX-201 to ensure client-server communication privacy and correct user authentication:

• RADIUS (client authentication only)

• SSL for Web-based management application

• SSH for Secure Shell communication session

• SNMPv3 for secure SNMP sessions.

Ethernet OAM

ETX-201 provides tools to monitor and troubleshoot an Ethernet network and quickly detect failures. Two OAM types are provided:

• End-to-end (path) based on IEEE 802.1ag and Y.1731 for continuity check, non-intrusive loopback and performance management, including Frame Delay, Frame Delay Variation, Frame Loss, Availability etc

• Single segment (link) according to IEEE 802.3ah for remote management and fault indication, including remote loopback, dying gasp, and MIB parameters retrieval.

Appendix C provides more detailed description of the OAM functions.

Remote Monitoring

The Syslog protocol is used by ETX-201 to generate and transport event notification messages over IP networks to the central Syslog server. The Syslog operation is compliant with the RFC 3164 requirements.

ETX-201 supports DDM (Digital Data Management) SFPs according to Sff-8472 Version 9.3.

DHCP Client

When enabled, the DHCP client of ETX-201 automatically requests an IP address, IP mask and default gateway from the DHCP server. In addition, ETX-201 automatically defines a network manager with a valid IP address and subnet mask.

Statistics Collection

ETX-201 collects Ethernet performance statistics for the physical layers of the network/user ports, OAM flows and VLANs.

In addition to the regular statistics collection, ETX-201 allows you to receive reports when one of the available counters (physical layer or end-to-end OAM) rise above or drop below the set thresholds within the specified sampling period of time. These reports can be sent as SNMP traps to the defined network management stations and/or be written to the event log.

Dying Gasp

Some of the ETX-201 units feature a dying gasp mechanism. If a power failure occurs, ETX-201 sends traps to the defined network management stations, informing the failure.


ETX-201 Ver. 3.6 Physical Description 1-5

Network Time Protocol

The Network Time Protocol (NTP) provides the means of synchronizing all managed elements across the network to a reliable clock source. ETX-201 supports the client side of the NTP v.3, based on RFC 1305.

Diagnostic Tools

A built-in ping utility allows checking IP connectivity by pinging remote IP hosts.

The Trace Route application can quickly trace a route from ETX-201 to any other network device.

Loopbacks can be closed on any of the ETX-201 ports. Only one loopback can be active at a time. Layer-2 loopback with MAC address swapping enables end-to-end connectivity verification.

The quality of the copper cables, connectors and terminations can be checked by running a Virtual Cable Test (VCT). During the test, ETX-201 transmits a signal of known amplitude (+1V) down each of the two pairs of an attached cable, testing the Rx and Tx pairs sequentially. The signal travels down the cable until it reflects off of a cable imperfection. By measuring the magnitude of the reflection and the time it takes for the reflection to come back, ETX-201 estimates the approximate distance to the location of a cable break or short.

1.2 Physical Description

Figure 1-3 shows a 3D view of a typical ETX-201 unit.

1-6 Functional Description ETX-201 Ver. 3.6

1.3 Functional Description

Network Port Redundancy

The two network interfaces can be configured to operate either independently, as two separate Ethernet interfaces, or used as a single Ethernet interface with line redundancy.

• Link aggregation mode in accordance with IEEE 802.3ad (without LACP). This mode inherently provides redundancy: if one of the Gigabit Ethernet ports fails, the traffic is transmitted on the other.

• 1:1 bidirectional protection (redundancy) mode. In this mode, at any time only one of the ports is actively carrying traffic. With 1:1 bidirectional redundancy, the recovery mode (revertive or non-revertive), and the restoration time in the revertive mode, can be selected in accordance with the application requirements.

Using Link Aggregation

The two network Ethernet ports can be operated as a single logical interface, using link aggregation in accordance with IEEE 802.3ad without LACP (Link Aggregation Control Protocol). In the virtual link group only one link transmits at a time. If a failure occurs on the transmitting link, ETX-201 switches to the standby link in the group. The flip is performed by reassigning destination ports.

With link aggregation, the two network ports serve as a single logical interface. The two ports must be connected to the same switch/router, as shown in Figure 1-4.

Figure 1-4. Link Aggregation Redundancy Mode

Using link aggregation inherently provides redundancy, because that if one of the network ports fails, the other can continue transferring traffic. Therefore, link aggregation per IEEE 802.3ad has inherent APS (Automatic Protection Switching) characteristics.

Failure of one the links is detected by sensing the loss of valid signals at a port, in which case the whole traffic is sent through the remaining port. The switching time is less than a second.

Link aggregation always provides revertive recovery, because that as soon as the down port returns to normal, the full bandwidth is again available.

The equipment connected to the network ports must use compatible switching criteria for redundancy to be available:

• For networks using Layer 2 switching: the criterion is signal loss


ETX-201 Ver. 3.6 Functional Description 1-7

• For networks using Layer 3 routing: the router must support IEEE 802.3ad or other link aggregation protocol that views the aggregated link as a single logical interface.

As the two GbE ports serve as a single logical interface, the learning tables do not change as a result of the interface flip.

Using 1:1 Bidirectional Redundancy As an alternative to link aggregation, the two ETX-201 network ports can be configured for 1:1 bidirectional mode (dual homing). With this mode, two topologies can be used:

• Connection of both network ports to the same switch/router, as shown in Figure 1-4.

• Connection of the network ports to different switch/routers, as shown in Figure 1-5. The main advantage of this topology is its higher availability, because each port can be routed along a different path through the network.

Figure 1-5. 1:1 Bidirectional Redundancy Mode (Dual Homing)

With 1:1 bidirectional redundancy mode, at any time only one of the ports is actively carrying traffic, and the other port serves as the backup port. A RAD proprietary redundancy algorithm, based on loss of the signal, is used to detect line failure. The protection switching (flipping) time is less than 1 second. It also depends on the network “relearning“ time or aging.

The recovery mode after a protection switching can be selected in accordance with the application requirements:

• Non-revertive mode – ETX-201 will not automatically flip back after the failed port returns to normal operation, but only when the currently used port fails, or after a manual flip command.

• Revertive mode – ETX-201 will flip back to the original port when it returns to normal operation. Flipping back can be delayed by specifying a restoration time, during which alarms are ignored. As a result, ETX-201 starts evaluating the criteria for protection switching (flipping) only after the restoration time expires, thereby ensuring that another flip cannot occur before the specified time expires.

When flip occurs, ETX-201 clears the MAC tables, enabling more efficient address relearning.


1-8 Functional Description ETX-201 Ver. 3.6

Fault Propagation

If a network link fails, ETX-201 propagates this condition to user ports (all or only some of them), see Figure 1-6. The user-configurable time-to-restore parameter specifies the time period ETX-201 waits before enabling user interfaces once the network interface is restored.

Figure 1-6. Fault Propagation

Diagnostic Loopbacks

ETX-201 supports the following diagnostics loopbacks:

• Layer-1 loopback performed at the PHY of the bridge ports. When the loopback is active the data forwarded to a bridge port is looped from the Tx path to the Rx path, disrupting the traffic. This loopback cannot pass through Ethernet bridges.

• Layer-2 loopback with MAC address swapping, when ETX-201 exchanges source and destination MAC addresses of the incoming packets. This loopback can be performed per VLAN (or EVC), it passes through Ethernet bridges and does not disrupt traffic flows, which are not being tested.

3.4 Configuration and Management Alternatives

After installation, there are no special operating procedures for ETX-201. Once it is powered up, the unit operates automatically. The unit operational status can be monitored constantly.

If required, ETX-201 can be reconfigured. ETX-201 can be managed using different ports and applications:

• Local out-of-band management via an ASCII terminal connected to the RS-232 port. Usually, preliminary configuration of the system parameters is performed via ASCII terminal. Once the ETX-201 host IP parameters are set, it is possible to access it via Telnet, ConfiguRAD or RADview for further configuration.

• Remote inband management via user or the network ports or out-of-band via the last user port. Remote management is performed using Telnet, or ConfiguRAD (RAD’s Web-based application), or RADview (RAD’s SNMP-based management system). Alternatively, ETX-201 can be managed via a third-party SNMP-based NMS (refer to Chapter 6 for trap list).

The following functions are supported by the ETX-201 management software:

• Viewing system information

• Modifying configuration and mode of operation, including setting system default values and resetting the unit

• Monitoring ETX-201 performance

• Initiating connectivity tests

• Uploading and downloading software and configuration files.


ETX-201 Ver. 3.6 Configuration and Management Alternatives 3-7

Working with Terminal

ETX-201 has a V.24/RS-232 asynchronous DCE port, designated CONTROL and terminated in a 9-pin D-type female connector. The control port continuously monitors the incoming data stream and immediately responds to any input string received through this port.

The ETX-201 control port can be configured to communicate at the following rates: 9.6, 19.2, 38.4, 57.6 or 115.2 kbps.

To start a terminal control session:

1. Make sure all ETX-201 cables and connectors are properly connected.

2. Connect ETX-201 to a PC equipped with an ASCII terminal emulation application (for example, Windows Hyper Terminal or Procomm).

3. Turn on the control terminal PC and set its port parameters to 115,200 baud, 8 bits/character, 1 stop bit, no parity.

4. Set the terminal emulator to ANSI VT100 emulation (for optimal view of system menus).

5. When the initialization and self-test are over, press any key to display the user name and password entry fields.

Login

To prevent unauthorized modification of the operating parameters, ETX-201 supports two access levels: .

• Superuser can perform all the activities supported by the ETX-201 management facility, including defining new users.

• User’s access rights (full control or read only) are defined by the superuser. Users are not allowed to create new users.

It is recommended to change default passwords to prevent unauthorized access to the unit.

To enter as a superuser:

1. Enter su for user name.

2. Enter 1234 for password.

This allows you to configure all the parameters of ETX-201, and to change the su and user passwords.

To enter as a user:

1. Enter user for user name.

2. Enter 1234 for password.

If the password is invalid in three consecutive attempts, the system becomes inaccessible for 15 minutes.

Note

Note



Choosing Options

How to use the terminal to perform a desired activity:

• To select a menu item, type the corresponding line number and then press <Enter>. This will either …

… display a submenu or a parameter selection screen …

or …

… let you type the (free text) parameter value in the same row

or …

… toggle the current value of the corresponding parameter (relevant to ENABLE/DISABLE or ON/OFF selections).

• The type of response to be expected after selecting a menu item is indicated as follows:

> Selecting that item will display a submenu or a parameter selection screen.

... Selecting that item will let you type the desired value in the same line.

Nothing When neither symbol is displayed, selecting that item will toggle the current selection, now shown in brackets (for example, this will change ENABLE to DISABLE or vice versa).

• When a menu does not fit on one screen (because it includes many lines), it is displayed on two consecutive pages. In this case, you will see …(N) after the last line on the first page and …(P) after the last line on the second page:

While on the first page, press N to display the second page

While on the second page, press P to return to the first page.

• When a configuration screen is organized as a table, a special set of keys is used for navigation within the table (such screens always have a ? (help) option that displays these keys). The following keys may be used for navigation within tables:

L – move to the left R – move to the right

^D – scroll down ^U – scroll up

In addition, the following shortcuts are also available:

Tab – select the next cell that may be changed

G followed by <row number>,<col number> – select a specific cell. For example, type G2,5 to select the fifth cell in the second row.

• The current value of a parameter is listed within parentheses ( ). To change a parameter value on a parameter selection screen:

Type the line number corresponding to the desired value, and then press <Enter>



To enter a value which requires free text entry, type in the desired string and then press <Enter>. Use backspace to erase the current string.

Note that whenever applicable, the allowed range of values of a parameter is listed within square brackets [ ].

• The entry is checked after pressing <Enter>, and it is accepted only if it is valid:

If you make an error, for example, if you press a key not active on the current screen or select an invalid parameter value, an ERROR indicator appears in the right-hand corner. This indicator disappears as soon as you make a correct operation.

If you select a parameter value incompatible with the current operating state or other parameters, you will see a message that explains the error.

• When done with the current screen, press <Esc> to return to the previous screen, or type ! to return directly to the main menu.

Ending a Terminal Configuration Session

To end the current terminal session:

• Type &.

After a session is ended, it is necessary to enter again a valid user name and password to start a new session.

Chapter 4

Configuration This chapter illustrates the configuration ETX-201 screens and explains their parameters.

Menu tree of the ETX-201 management software is shown in Chapter 3.

For user’s convenience, parameters that are mandatory for configuration, such as IP settings of the ETX-201 host or forwarding mode, are given in the Quick Setup menu (Main menu > Configuration > Quick Setup). This menu is explained in the Quick Start Guide at the beginning of the manual, and the menu parameters are explained in the relevant sections of the configuration chapter.

4.1 Configuring ETX-201 for Management

Usually, initial configuration of the management parameters is performed via an ASCII terminal. Once the ETX-201 host IP parameters are set, it is possible to access it via Telnet, ConfiguRAD or RADview for operation configuration. Perform the following steps in order to configure ETX-201 for management:

• Configuring IP Host Parameters

• Entering Device Information

• Configuring ETX-201 Communities

• Configuring the Host Encapsulation

• Configuring the Network Managers.

Configuring IP Host Parameters

ETX-201 can be managed by a network management station which is located on the LAN connected to the one of the unit’s Ethernet ports. In order to establish a proper connection, it is necessary to configure the following: host IP address, subnet mask, default gateway. Also it is possible to enable or disable the ETX-201 DHCP client.

Chapter 4 Configuration Installation and Operation Manual

Figure 4-1. Host Menu

Configuring the DHCP Client

To facilitate integration of a new device into a DHCP IP network, if no IP address has been manually configured, ETX-201 automatically requests one from the DHCP server upon booting. ETX-201 is shipped with the DHCP client set to Enable.

To enable the DHCP client:

1. From the System menu, select Host.

The Host menu appears.

2. From the Host menu, select DHCP Client, and choose Enable.

ETX-201 starts broadcasting requests for an IP address. When the DHCP server is found, ETX-201 receives from it all necessary host IP parameters.

3. From the Host IP menu, select DHCP Status to view the current status of the ETX-201 DHCP client:

Server ID – IP address of the DHCP server

Lease expiration time – Time when the IP address lease expires

Current status – Current status of the DHCP client (Locating available server, Waiting for confirmation of lease, etc)

When the IP address lease is about to expire, DHCP client automatically requests lease extension.

To disable the DHCP client:

• From the Host menu, select DHCP Client, and choose Disable.

ETX-201 sets the host IP address to 0.0.0.0, while preserving the IP mask and default gateway values. Telnet or HTTP connection to ETX-201 is disrupted and the unit can be accessed only using a previously defined default IP address (see the next section for instructions on how to enter a default IP address).

Note

Installation and Operation Manual Chapter 4 Configuration


Managing IP Parameters of the ETX-201 Host

ETX-201 allows entering IP parameters manually or using parameters acquired from the DHCP server.

To define the IP parameters manually:

1. Disable the DHCP client.

ETX-201 releases the current IP address by sending the release message to the DHCP server, sets all host IP parameters to 0.0.0.0 and reboots itself automatically.

2. From the Host menu, perform the following:

Select IP Address to define the host IP address

Select IP Mask to define the host IP mask.

Select Default Gateway to set the default gateway IP address

Select Default IP to enter a default IP address. Configuring a default IP address is necessary if you want to preserve a Telnet or HTTP connection to ETX-201 after having disabled its DHCP client.

The default gateway must be in the same subnet as the host.

To acquire a new IP address from the DHCP server:

1. From the Host IP menu, set all host IP parameters (host IP, IP mask and default gateway) to 0.0.0.0.

2. Enable the DHCP client.

ETX-201 reboots itself automatically and acquires new IP parameters from the DHCP server at startup.

Entering Device Information

The ETX-201 management software allows you to assign a name to the unit, add its description, specify its location to distinguish it from the other devices installed in your system, and assign a contact person.

To enter device information:

1. From the System menu, select Management.

2. From the Management menu, select Device Info.

The Device Info menu appears (see Figure 4-2).

3. From the Device Info menu, select Device Name and enter a desired name for the ETX-201 unit.

4. Select Device Location and enter the desired name for the current ETX-201 location.

5. Select Contact Person and enter name of a contact person.

Figure 4-3. Host (Management) Menu



Configuring the Host Encapsulation

ETX-201 management software allows you to create a dedicated management VLAN in order to separate management traffic from the user data. In addition, it is possible to restrict the management traffic to the network or user ports or allow inband management via any of the ETX-201 ports.

To configure the host encapsulation:

1. From the Host menu (Figure 4-3), select Encapsulation.

The Encapsulation menu is displayed (see Figure 4-4).

2. From the Encapsulation menu, do the following:

Select Host tagging, and choose Tagged or Untagged to consider or ignore the VLAN tagging of the management traffic coming from the management station.

If the host tagging is enabled, select Host VLAN ID to enter the ID of the host VLAN (1–4094).

If the host tagging is enabled, select Host VLAN priority to specify priority of the host VLAN (0–7).

Select Security Definition and define the ports from which the manager can access ETX-201. Possible values depend on the VLAN mode (aware or unaware) of the ETX-201 bridge, selected under the Bridge menu (see Configuring the Bridge below).

All – ETX-201 can be accessed via any of its ports (available in the VLAN-aware and VLAN-unaware mode). In the VLAN-aware mode an ETX-201 port and the ETX-201 host must be members of the same VLAN to allow access to the unit via this port.

Network Only – ETX-201 can be accessed via the network port only (available only in the VLAN-unaware mode)

User Only – ETX-201 can be accessed via one of its user ports (available only in the VLAN-unaware mode).

Controlling Management Access

You can enable or disable access to the ETX-201 management system via an SNMP, Telnet or Web-based application. By disabling SNMP, Telnet or Web, you prevent unauthorized access to the system when security of the ETX-201 IP address has been compromised. When SNMP, Telnet and Web access is disabled, ETX-201 can be managed via an ASCII terminal only. In addition, you can limit access to the device to only the stations defined in the manager list. Table 4-1 details management access implementation, depending whether the network managers are defined or not.

To define the management access method:

1. From the Management menu, select Management Access.

The Management Access menu appears (see Figure 4-13).

2. From the Management Access menu, select Telnet/SSH Access to configure Telnet access, select SNMP Access to configure SNMP access, or select Web Access to configure Web access.

3. Define access mode for each management method:

Enable (Telnet, SNMP or Web access is enabled)

Disable (Telnet, SNMP or Web access is disabled)

Manager Only (Access is allowed only for the stations appearing in the manager list)

Enable Secure (Secure access (SSH-enabled for Secure Shell or SSL-enabled for Web) is enabled)

Manager Only Secure (Secure access (SSH-enabled for Secure Shell or SSL-enabled for Web) is allowed only for the stations appearing in the manager list).

Defining Access Policy

Access policy allows configuration of multiple authentication protocols. User authentication is performed in the order the methods are selected. If the first authentication method is not available or the user is not found, the next selected method is used.

To define the access police:

From the Access Policy menu (Configuration > System > Management > Management Access > Access Policy), configure the following:

• 1st Level (First level of authentication):



RADIUS (ETX-201 uses an authentication database stored at the RADIUS server)

Local (ETX-201 uses a locally stored authentication database)

• 2nd Level (Second level of authentication. Available only when the 1st level authentication is set to RADIUS.):

None (Second authentication level is disabled, access to ETX-201 is allowed only using the 1st level method.)

Local (ETX-201 uses locally stored authentication database)

Configuring RADIUS Client

The RADIUS (Remote Authentication Dial-In User Service) is a client/server security protocol. Security information is stored in a central location, known as the RADIUS server. RADIUS clients, such as ETX-201, communicate with the RADIUS server to authenticate users. ETX-201 supports up to four RADIUS servers.

To configure RADIUS client:

1. From the RADIUS Parameters menu (Configuration > System > Management > Management Access > RADIUS Parameters), type f to select a RADIUS server that you intend to configure.

The Server Status parameters indicate the current status of the selected server. The status can be one of the following:

Connected – Selected server is currently operating as an active RADIUS server

Not Connected – Selected server is a backup RADIUS server

Disconnected – Connection to the selected server has timed out.

2. Configure the following parameters:

Server Access (Disables or enables the RADIUS server)

Server IP Address (IP address of the RADIUS server)

Key String (The shared secret is a password used by RADIUS to authenticate the client. ETX-201 encrypts the user-password, if present; using the secret it shares with the RADIUS server.): Any alphanumeric string up to 16 characters

Number of retries (The number of retries to be made when sending request to the RADIUS server): 0–5

Timeout (The maximum time ETX-201 waits for a single request response from the RADIUS server (in seconds). After this time the request is retransmitted.): 0–60

Authentication Port (The UDP port number to be used for the RADIUS authentication application. Make sure to define the same value in the RADIUS server.): any valid UDP port number.

4.2 Configuring ETX-201 for Operation

The recommended configuration procedure for ETX-201 includes the following stages:

1. Configuring device-level parameters (link protection)

2. Configuring network and user Ethernet interfaces at the physical level

3. Configuring internal bridge

4. Configuring QoS parameters.

Configuring the Link Protection

The ETX-201 uses two network link protection modes:

• LAG (Link Aggregation Group)

• 1:1.

Before configuring the link protection make sure that both network ports have identical bridge port parameters (ingress filtering mode, port VID etc) and are the members of the same VLAN.

Note

Note


4-18 Configuring ETX-201 for Operation ETX-201 Ver. 3.6

To select the link redundancy method:

1. From the System menu (Configuration > System), select Protection.

The Protection menu (LAG mode) is displayed (Figure 4-16).

2. From the Protection menu select Redundancy Method and choose the required method:

LAG – Both network links are combined into one virtual group, but only one link transmits data at a time. If a failure occurs on the transmitting link, ETX-201 switches to the standby link in the group.

• In the LAG mode the first link to have its Administrative Status to be set to Up becomes an active link of the group and starts data transmission. Refer to the Configuring Network and User Ethernet Interfaces section below for instructions on how to change the administrative status of the link.

• In the LAG mode both network links receive data, but only one of them transmits.

1:1 – Both network ports operate independently, one of them is active, the other – on standby. The traffic is automatically switched to the standby port in case the active network port or its link fails.

ETX-201 user bridge ports support filtering of incoming traffic, accepting all frames or only those, which have VLAN tags. The incoming frames can be assigned PVID and priority by the user bridge ports.

Note



To configure the user bridge ports:

1. From the Bridge menu, select Bridge Port.

The Bridge Port menu is displayed (see Figure 4-25).

2. From the Bridge Port menu, type f to select the user bridge port that you intend to configure, and set the following parameters:

Ingress Filtering (Controls filtering of the incoming traffic)

Enable (User bridge port accepts only frames with tags of the VLANs, which include this user port as a member.)

Disable (User bridge port accepts all incoming frames)

Accept Frame Type (Specifies the frame types to be accepted by the user bridge port)

All (User bridge port accepts all frames (tagged, untagged, priority-tagged). Untagged and priority-tagged frames receive PVID of the user bridge port.)

Tag only (User bridge port accepts only tagged frames, discarding untagged and priority-tagged)

The Ingress Filtering and Accept Frame Type parameters are available only in the VLAN-aware mode.

Port VID (Port VID to be added by the user bridge port to the arriving frames): 1–4094

PVID operation depends on the tag handling mode:

• None – PVID is added to the untagged and priority-tagged frames only.

• Stack – PVID is added to all arriving frames (tagged, untagged or priority tagged).

Default Priority Tag (Default priority tag to be added by the user bridge port to the untagged frames. No default priority tags are added to the frames arriving with assigned port priority): 0–5.

Tag Handling (Defines if user ports add port VID only to untagged or to all arriving frames)

None (PVID is added to the untagged and priority-tagged frames only)

Stack (PVID is added to all arriving frames)

Configuring the VLAN Membership

Each ETX-201 port can be defined as a VLAN member. The ports can also be configured to add or to strip the VLAN tag at the egress.

To configure the VLAN membership:

1. From the Bridge menu, select VLAN Membership.

The VLAN Membership menu is displayed (see Figure 4-26).

2. From VLAN Membership menu, type a and add a new VLAN, and enter the new VLAN number or type f to select an existing VLAN, to which you intend to assign the ETX-201 port.

3. When the number of the required VLAN is displayed at the top of the menu, do the following:

Select Egress Tagged Ports to assign network and/or user ports to be the tagged members of the current VLAN. These ports add the current VLAN tag to all frames at egress.

Select Egress Untagged Ports to assign network and/or user ports to be the untagged members of the current VLAN. These ports strip the current VLAN tag from all frames at egress.

Each port can be an untagged member in only one VLAN.

To assign an ETX-201 port to a VLAN:

1. From the Egress Tagged Ports or Egress Untagged Ports menu, type a to add a port.

The display changes, entering the Add mode (see Figure 4-26).


1. Select the ETX-201 port range, displayed as [1 – 3], [1 – 4] or any other combination, depending on the number of ports available in ETX-201 and enter the desired port number.

Note



2. Repeat step 1 for all ETX-201 ports hat you intend to define as egress-tagged or egress-untagged for the current VLAN.

3. Select Save All to save the changes.

4. Press <Esc> to return to the VLAN Membership menu.

5. Save the changes.

To delete ETX-201 ports assigned to VLAN:

1. From the Egress Tagged Ports or Egress Untagged Ports menu, select Delete Range and specify network or user ports that you intend to disconnect from the current VLAN and save the changes

The ports which will be disconnected are selected one after another or as a group in the x-y format in the ascending order.

For example, if you want to disconnect ports 1, 2 and 3 from the VLAN, you can do it in the following succession: Delete Range 1, Delete Range 2, Delete Range 3, Save All.

Alternatively, you can specify the port range and do it in just two steps, as follows: Delete Range 1-3, Save All.

2. Press <Esc> to return to the VLAN Membership menu.

Configuring OAM

ETX-201 has the following capabilities for providing operation, administration, and maintenance (OAM) in the packet-switched networks (see Appendix C for detailed explanation of the OAM functionality):

• Continuity check

• Non-intrusive loopback which used to detect loss of bidirectional continuity.

• Performance measurements (per service).



To configure the OAM:

1. Create an EVC (Ethernet Virtual Connection), define its ID and VLAN

2. Configure the ME (Maintenance Entity)

1. Assign IDs to the local and remote MEPs (Maintenance Entity Endpoints)

2. Define OAM and continuity verification modes

3. Provide destination addresses for OAM messages

4. Set default priority, if you do not intend to define OAM services

3. Enable OAM services, if necessary

4. Configure the enabled OAM services:

1. Define performance monitoring mechanism

2. Provide service priority

3. Set objectives (thresholds) for measurement parameters.

Configuring the EVC

EVC (Ethernet Virtual Connection) is an association of two ETX-201 units used for OAM message exchange. Currently ETX-201 supports up to 16 EVCs.

To add and configure an EVC:

1. From the EVC menu (Configuration > OAM > End-to-End), type a to add an EVC.

2. Enter a new EVC number.

3. Type f or b to select an EVC you intend to configure and perform the following:

4. Select EVC ID and enter an alphanumeric string of up to 100 characters. This string is unique and it is used for EVC identification in the maintenance domain (managed network). The EVC ID must be the same for the local and remote units.

5. Define EVC SP VLAN, which is a VLAN tag when sending OAM messages over the current EVC: 1–4094.

ETX-201 Configuration>OAM>End-to-End EVC[1 - 64] ... (1)

Figure 4-27. EVCs Menu



Configuring the MEP

Once the EVC was created, it is necessary to define its MEPs (Maintenance Endpoints) and configure other OAM parameters.

To configure the MEP:

• From the MEP menu (Configuration > OAM > End-to-End > MEP), define the following:

Local MEP ID (Identification number of the local maintenance endpoint. It must be different from the remote MEP ID and unique for the maintenance domain.): 0–65535

Remote MEP ID (Identification number of the remote maintenance endpoint, terminating the maintenance entity. It must be different from the local MEP ID and unique for the maintenance domain.): 0–65535

OAM Mode (OAM behavior):

Disabled (No continuity check is performed)

Initiate (ETX-201 initiates and reacts to OAM messages)

React (ETX-201 only reacts to OAM messages, without initiating them)

Continuity Verification Mode (Continuity check method):

Disabled (No continuity check is performed)

LB-based (Continuity check is performed via loopback messages)

CC-based (Continuity check is performed via received OAM packets)

When the OAM mode is set to Initiate, the continuity verification mode can be either LB- or CC-based only. In the React OAM mode only CC-based verification is available.

OAM Destination Address Type (Type of the MAC address to which the OAM messages are sent):

Multicast (RAD proprietary)

Unicast (user-defined)

OAM Destination MAC Address (User-defined MAC address to which the OAM messages are sent. It is available only if the OAM destination address type is set to Unicast.)

Default Priority (Priority of the OAM messages, when no services are defined on the current EVC): 0–7

Configuring Quality of Service (QoS)

ETX-201 supports configuration of two QoS categories: priority and rate limitation. QoS configuration is performed via the QoS menu (Main menu > QoS).

Configuring the Traffic Priority

ETX-201 provides four priority queues for each user port. User traffic can be prioritized according to the VLAN priority, DSCP, IP TOS or per port basis.

To select the traffic priority type:

1. From the Configuration menu, select QoS.

The QoS menu is displayed.

2. From the QoS menu, select Priority.

The Priority menu is displayed (see Figure 4-30).

3. From the Priority menu, select Classification and choose one of the following traffic prioritization methods:

802.1p (Traffic is prioritized according to VLAN priority)

DSCP frame DSCP field (Traffic is prioritized according to the Differentiated Services Codepoint, as specified in RFC 2474).

TOS (Traffic is prioritized according to IP ToS field)

Per Port (Traffic is prioritized according to port default priority).

To define the priority mapping:

1. Once the priority type is defined, select Mapping from the Priority menu.

The Mapping menu appears. The Mapping menu changes according to the selected priority type (802.1p, DSCP, TOS, per port). Figure 4-31 illustrates the Mapping menu for the 802.1p priority.

2. From the Mapping menu, define the following:

802.1p priority – assign each priority tag, supported by IEEE 802.1p (1–7) to a specific priority queue (traffic class 0 (lowest), traffic class 1–3)

DSCP priority – assign each DS codepoint (0–7) to a specific priority queue (traffic class 0 (lowest), traffic class 1–3)

TOS priority – assign each IP ToS field value (0–63) to a specific priority queue (traffic class 0 (lowest), traffic class 1–3)

Per port priority – assign priority to the user traffic according to the default priority of a bridge port.

Configuring Rate Limitation

ETX-201 supports data rate limitation at the egress and ingress of the network and user ports. ETX-201 limits the data rate proper, without taking into account Ethernet frame intergaps.

Configuring Ingress Rate Limitation

Via ingress rate limitation the user controls the rate of traffic received at the network and user interfaces. The traffic that exceeds the selected rate limitation value for an ETX-201 port is dropped. In addition to that ETX-201 defines maximum packet burst for each rate limitation value. This enables service providers to compensate their subscribers for underused bandwidth by allowing temporary traffic bursts. Also, the rate limitation can be applied to all packets or to their certain types (broadcast, multicast, etc).



To configure the ingress rate limitation:

1. From the Rate Limitation menu (Configuration > QoS > Rate Limitation), select Ingress.

The Ingress menu is displayed (Figure 4-32).

2. From the Ingress menu, type f to select the network or user port to which you intend to apply rate and burst limitation.

3. Select Rate Limitation and define the maximum ingress data rate allowed on the port (see Table 4-2).

4. Select Burst Size and define the maximum allowed size of the packet buffer (in kilobytes) to be used by the port when traffic bursts occur. See Table 4-2 for the allowed burst values depending on configured port rate limitation. Traffic bursts permitted only if the traffic has been sent to the ETX-201 below the rate limit for a certain period of time.

5. Select Limit Packet Type and choose a packet type to which the rate/burst limitation is to be applied:

All – The limitation is applied to all arriving packets

Broadcast – The limitation is applied to broadcast packets

Multicast & Flooded – The limitation is applied to broadcast, multicast and flooded packets

Broadcast & Multicast – The limitation is applied to broadcast and multicast packets

Broadcast – The limitation is applied to broadcast packets.

Transferring Software and Configuration Files

This section presents procedures for installing new software releases into the ETX-201 units and transferring configuration files.

ETX-201 stores two software versions, each of them in one of the two 1.15 MB partitions of its flash memory, which also contains a boot program. The software is stored in compressed format. The main version is decompressed and loaded into the ETX-201 RAM upon power-up. The backup software is kept for backup purposes. If the main software becomes corrupted, you can swap it with the backup. By default, ETX-201 is delivered with active software only.



New software releases are distributed as *.img files, which are downloaded to ETX-201. When starting a download, ETX-201 erases the current backup and places the new software in the backup partition. When downloading is complete, the unit checks the integrity of the new software file. If it is correct, the backup and active files are swapped. The new software release becomes active and the former active software becomes the backup. If a failure occurs during downloading, the new version is erased. In this case, only one version is left stored in the flash memory. The backup software can be downloaded to the unit and swapped with the main software later.

Configuration files can be uploaded for storage and backup.

Management software allows file transfer via TFTP only. The software files can also be downloaded to ETX-201 via Boot Manager, using XMODEM or TFTP, as explained in Appendix B.

To transfer files via TFTP:

1. From the Main menu, select Utilities.

The Utilities menu appears.

2. From the Utilities menu, select File Utilities.

The File Utilities menu appears.

3. From the File Utilities menu, select S/W & File Transfer using TFTP.

The S/W & File Transfer using TFTP menu is displayed (see Figure 4-49).

4. From the S/W & File Transfer using TFTP menu, perform the following:

Select File Name, and enter a file name:

For downloading, you specify name of the file, which is to be downloaded to ETX-201.

For uploading, you specify a name, under which the file is going to be saved on the remote server.

Select Command to start the desired procedure:

NoOp (TFTP file transfer is disabled)

SwUpload (Saving a software file on a remote server)

SwDownload (Transferring a software file to ETX-201)

SwDownloadAndReset (Transferring a software file to ETX-201 and resetting the unit)

SwDwnLoad2BkupStorage (Transferring a software file to the backup partition of ETX-201)

ConfigUpLoad (Saving a configuration file on a remote server)

ConfigDwnLoad (Transferring a configuration file to ETX-201)

StateUpLoad (Collection of TFTP statistics and upload it to the NMS).

When the upload statistics command is received, ETX-201 starts collecting the data for intervals, creating a separate file for each interval. The file name is a concatenation of fileName value and the interval number. Once the file is created, it is compressed and



uploaded to the NMS. If the upload is successful, ETX-201 empties the buffer and proceeds to the next interval. The intervals are configured via SNMP only.

Select Server IP, and enter IP address of TFTP server.

Define Retry Timeout (Interval between connection retries in seconds).

Define Total Timeout (TFTP connection timeout in seconds)

Select Save to save the changes.

ETX-201 starts file transfer.

Swapping the Software Files

When the software file is downloaded to the backup partition, it can be swapped with the main software file.

To swap software files:

1. From the File Utilities menu, select Swap Main Application File With Backup.

ETX-201 displays the following message: Backup application file will be active after reset. Continue ??? (Y/N).

2. Type Y to complete the swap.



Resetting ETX-201

ETX-201 supports two types of reset:

• Reset to the default setting

• Overall reset of the device.

Resetting ETX-201 to the Defaults

You can reset ETX-201 to its default settings. All configuration parameters can be reset the their default values, or you can reset ETX-201 without affecting its management settings (host IP address, mask, default gateway and the network managers).

Running Loopbacks

ETX-201 supports two loopback types:

• Regular loopback run at the PHY of the bridge ports. When the loopback is active the data forwarded to a bridge port is looped from the Tx path to the Rx path.



• MAC Swap loopback which supports exchanging source and destination MAC addresses of the incoming packets. The user can define loopback direction (ingress or egress) and type of data to be looped back (all data except for packets with management VLAN tag or only packets with a specific VLAN tag).

To run a regular loopback:

1. From the Diagnostics menu, select Loopbacks.

The Loopbacks menu is displayed (Figure 6-13).

2. From the Loopbacks menu, type f to select the port that you intend to run loopback on.

3. From the Loopbacks menu, configure the following:

Loopback Timeout (Specifies a period of time, after which the loopback is automatically disabled. Setting timeout to 0 disables the timeout.): 0–3600 seconds.

Loopback State (Controls loopback activation)

Enable – Loopback is activated Disable – Loopback is deactivated.

Only one loopback can be run at a time.

To run a MAC Swap loopback:

1. From the Diagnostics menu, select Loopbacks.

The Loopbacks menu is displayed (Figure 6-13).

2. From the Loopbacks menu, type f to select the port that you intend to run loopback on.

3. From the Loopbacks menu, configure the following:

MAC Swap (Enables or disables exchanging source and destination MAC addresses:

Enable – MAC address swap is enabled

Disable – MAC address swap is disabled

Looped Data (Defines which data will be looped back):

All Except MNG – All packets, excluding the ones with management VLAN tag, are looped back. The management traffic remains intact.

Specific VLAN – Only packets with specific VLAN tag are looped back.

• MAC Swap loopback cannot be run on network port 2.

• Specific VLAN mode is not available for a bridge port with tag handling set to Stack.

• All Except MNG mode is not available for the user ports.

VLAN ID (Specifies VLAN value for the Specific VLAN mode): 1–4094

Specific VLAN ID must be different from the host VLAN ID.

Testing the Cables

The user can check the quality of the copper cables, connectors and terminations by running a Virtual Cable Test (VCT). During the test ETX-201 transmits a signal of known amplitude (+1V) down each of the two pairs of an attached cable, testing the Rx and Tx pairs sequentially. The signal travels down the cable until it reflects off of a cable imperfection. By measuring magnitude of the reflection and the time it takes for the reflection to come back, ETX-201 estimates an approximate distance to the location of a cable break or short.

To run the VCT:

1. From the Diagnostics menu, select VCT Test.

The VCT Test menu is displayed (see Figure 6-14).

2. From the VCT Test menu, type f to select an ETX-201 user port, which cable you intend to test.

3. From the VCT Test menu, select Start Test to initiate the VCT on the selected port.

The VCT results are displayed for the receive and transmit wires:

Tx/Rx test results:

Fail – The CAT5 cable pair has a non-compliant termination i.e. less than 85 or greater than 115.

Normal – The CAT5 cable pair is normal and has a termination between the IEEE specified limits of 85 to 115�

Open – The CAT5 cable pair is not terminated.

Short – The CAT5 cable pair is shorted

Short to Pair A/B/C/D – The CAT5 cable pair is shorted to pair A/B/C/D



Coupled with Pair A/B/C/D – The CAT5 cable pair has abnormal coupling with pair A/B/C/D i.e. the impedance between the pairs is between 40 and 200.

Rx/Tx distance of reflection: Approximate distance to the location of a cable break or short in meters.

Appendix B

Boot Manager This appendix provides a description of the ETX-201 boot procedure via an ASCII terminal for downloading software.

The ETX-201 software is stored in flash memory in two sections, in the boot sector and in the file system. The boot sector holds a boot program that calls up the rest of the program from the file system.

The file system can hold two compressed copies of the ETX-201 code. One copy is called the operating file, and the other is called the backup file. The operating file is the default-executable ETX-201 code. The backup file is used whenever the operating file is absent or corrupted.

B.1 Booting ETX-201

ETX-201 boots up automatically. After powering up, no user intervention is required, except when the user wants to access the file system to modify or update the software or the ETX-201 configuration.

Accessing the Boot Manager

The Boot Manager menu is an option that allows the user to perform basic file transfer operations. These operations are all optional.

To access the Boot Manager menu:

• Press <Enter> several times immediately after powering up ETX-201.

The Boot Manager menu is displayed (see Figure B-1).

ETX-201 Ver. 3.6 Introduction C-1

Appendix C

Operation, Administration and Maintenance (OAM) This appendix describes the Ethernet OAM functionality of ETX-201.

C.1 Introduction

Currently ETX-201 supports pre-standard implementation of Ethernet OAM based on Y.1731.

ETX-201 has the following capabilities for providing operation, administration, and maintenance (OAM) in packet-switched networks:

• Continuity check

• Non-intrusive loopback used to detect loss of bidirectional continuity

• Performance measurements (per service).

Table C-1 lists the Ethernet OAM-related terms used in this appendix.

diagnostics OAM frames initiated by the MEP.

MEP Service Instance

Source

The receiver of OAM frames in each Service Instance

MEP Service Instance

Destination

C.2 Reference Architecture

Figure C-1 illustrates two OAM flows:

• OAM flow originating from the CPE

The CPE-to-CPE OAM flow is transferred transparently by ETX-201 and treated as data.

• OAM flow originating from the ETX-201 devices.

The ETX-201 OAM flow runs on an EVC Ethernet Virtual Connection). The ETX-201s terminate the OAM flow and can be referred as a Maintenance Entity (ME). Each device supports up to 16 such MEs. In this case, the ETX-201 units function as MEPs (Maintenance End-Points) and not as a MIP (Maintenance Intermediate Points) and all measurements are performed on the UNI_N to UNI_N segment.

Figure C-1. OAM Architecture

Installation and Operation Manual Appendix C Operation, Administration and Maintenance (OAM)

ETX-201 Ver. 3.6 OAM Entities C-3

Handling of OAM Levels

UNI_C to UNI_N Direction

In the UNI_C to UNI_N direction ETX-201 blocks all OAM messages with OAM level greater than 2. Messages with other OAM levels are passed transparently.

Network Ingress to UNI_N Direction

All OAM messages coming from the network ingress with the ETX MAC address or with a special OAM multicast address are sent to the CPU. All other OAM messages are passed transparently to the user ports as per the EVC definition.

C.3 OAM Entities

This section describes the hierarchy of OAM entities. Figure C-2 illustrates the relationship between UNI, EVC and Service Instance (COS ID), when one or more service instances belong to one EVC and one or more EVC belong to a UNI. From the OAM perspective, the continuity messages and defects are activated per EVC, and the PM is activated per service instance.

An EVC can belong only to one UNI in the same ETX-201.

Figure C-2. UNI, EVC and Service Instance (COS ID)

Figure C-3, Figure C-4 and Figure C-5 illustrate different combinations of UNIs, EVCs and Service Instances. Each UNI contains at lease one EVC and each EVC contains at lease one service instance.

• In the one EVC per UNI case (Figure C-3), the PM and CC are transmitted once.

C.4 OAM Flows

Figure C-6 illustrates a typical OAM traffic flow. The OAM message is transmitted from the source MEP 1 to the destination MEP 2 and the reply is transmitted back The source is also a destination for messages from the other direction.

The OAM interval is one second, so each NTU transmits one request and one reply and receive one request and one reply. A total of four messages are transmitted per second per service instance.

Figure C-6. OAM Flow

OAM Messages Addressing

The OAM defines two modes of addressing: unicast and multicast. Unicast addressing is used for the point-to-point connections, and multicast – in the cases where the MAC address of the destination MEP is not known. Currently ETX-201 supports point-to-point EVCs only.

OAM Message Association

On the receiver side the OAM frame is associated with an EVC and a service.


ETX-201 Ver. 3.6 OAM Flows C-5

EVC Association

When an OAM frame is associated with an EVC, the following steps are performed:

1. Request message reception

When a request message is received, the VLAN is extracted to find the EVC ID. The EVC ID found at the receiver is compared against the EVC ID in the frame. If the IDs are equal, further service association is made. If it is not found, the “EVC ID no match” notification is returned in the reply message.

2. Reply message reception

When a reply message is received, the VLAN is extracted to find the EVC ID. The EVC ID found at the receiver is compared against the EVC ID in the frame. If the IDs are equal, further service association is made. If it is not found, the frame is discarded and connectivity alarm is issued.

Service Association

When an OAM frame is associated with a service, the following steps are performed:

1. Request message reception

The class of service characteristics are extracted from the frame and must be matched to an entry in the EVC <-> services table at the receiver. If they are matched, the frame is processed. If not, the service ID is returned with the “Not Found” notification.

2. Reply message reception

The class of service characteristics are extracted from the frame and must be matched to an entry in the EVC <-> services table at the receiver. If they are matched, the frame is processed. If not, the frame is discarded.

Ethernet Loopback (ETH-LB)

The ETH-LB can be used to verify connectivity. The ETH-LB is performed by sending a request ETH-LB message to the remote unit and expecting an ETH-LB reply message back to verify connectivity. When the insertion rate of ETH-LB messages is much slower compared to data rate between the flow points, ETH-LB is suitable to perform in-service connectivity verification and to measure round trip delays.

The message is initiated by the local device and runs periodically making it suitable for fault detection.

Unicast ETH-LB request message is sent from a MEP to a specific MEP (remote device). The DA of the request message is a unicast MAC address of destination device. Upon receipt of the request message, the MEP responds with unicast ETH-LB reply message. The DA of the reply message is a unicast MAC address of requesting device, learned from request message.



Continuity Check (ETH-CC)

Ethernet Continuity Check (ETH-CC) can be used to detect continuity failures across EVCs between a given pair of edge service point on an EVC. Continuity failures are caused by:

• Major failures (link failure, device failure, network path failure etc)

• Minor failures (software failure, memory corruption, incorrect configuration etc).

The ETH-CC signal is generated by one MEP. Upon receipt of the first ETH-CC signal from a sending MEP, the receiving MEP detects continuity with sending MEP and expects to receive further periodic ETH-CC signals. Once the receiving MEP stops receiving periodic ETH-CC signals from sending MEP, it declares continuity failure. The MEP that detects the continuity failure notifies the operator by sending an alarm or a trap.

OAM Procedures

This section discusses the continuity check (CC) and the performance measurement (PM) procedures.

Continuity Check Procedure

The loopback message and the ETH-CC messages are used for continuity check. In case the services are defined and PM collection is enabled, they are also used to carry PM messages. If PM collection is disabled, the messages are used for continuity check only.

If the RX CC mode of the receiver is configured to CC-based, the continuity detection is based on ETH-CC. If the mode is set to LB-based, the continuity detection is based on ETH-LB. If the mode is disabled, the continuity detection is not performed.

ETH-LB Method

The ETH-LB method includes the following elements:

• Unicast ETH-LB transmission

Unicast ETH-LB request message is transmitted by a MEP (ETX-201) every 1 second. The transmitted Transaction Identifier is retained for at least 5 seconds after the unicast ETH-LB signal is transmitted. The Transaction Identifier must be changed for every unicast ETH-LB message, and no Transaction Identifier from the same MEP is allowed to be repeated within 1 minute.

• Unicast ETH-LB reception and reply transmission

Whenever a valid unicast ETH-LB request message is received by MEP (ETX-201), a unicast ETH-LB reply message is generated and transmitted to the requesting MEP. Every field in the unicast ETH-LB request message is copied to the unicast ETH-LB reply message with the following exceptions:

The source and destination MAC addresses are swapped.

The OpCode field is vendor-specific oxFE.


ETX-201 Ver. 3.6 OAM Flows C-7

The EVC and MEP ID are processed as follows: if the EVC/MEP ID do not exist in the device, it changes them to No Match” otherwise they are left intact.

• Unicast ETH-LB reply receipt

When a unicast ETH-LB reply message is received by a MEP (ETX-201) diagnostic flow termination function, it examines the TLVs returned in the unicast ETH-LB reply message. The signal is declared invalid if the TLVs do not match those sent in the corresponding unicast ETH-LB request signal, including MEP ID and EVC ID.

• Continuity declarations

Loss of Continuity and Connectivity Mismatch states are declared by the ETH-LB mechanism.

Loss of continuity declaration

After the source device sends an ETH-LB message a timer is set with a 3.52 second timeout. If the destination device does send reply within the timeout, the source enters the loss of continuity state. Upon reply from the destination, the source resets the timer to 23.5 seconds. Regarding the continuity check message, the source checks only the EVC ID with the MEP ID. When the source enters the loss of continuity state, it adds 24 to Unavailable Seconds counter. The 23.5 second period is calculated as a sliding window.

Loss of continuity state is cleared after 3.52 seconds with at least 21 reply messages from the destination. In this case the Unavailable Seconds counter decreased by 24.

Connectivity mismatch declaration

If the source EVC ID is not equal to the destination EVC ID as recorded in the reply message for 10 consecutive times, the source enters a misconnection state.

Misconnection state is cleared after 10 consecutive reply messages with the correct EVC name from the destination.

The Unavailable counter is maintained by the service according to the number of PM messages that did not receive replies. If a mismatch notification is received to the LB request, the frame is dropped and a reply message is not sent. This is why the service becomes unavailable (no reply) in case of mismatch and the unavailable counter is raised.

ETH-CC Method

The ETH-CC method includes the following elements:

• ETH-CC transmission

Unicast ETH-CC request message is transmitted by a MEP (ETX-201) every 1 second. The transmitted Transaction Identifier is retained for at least 5 seconds after the unicast ETH-CC signal is transmitted. The Transaction Identifier must be changed for every Unicast ETH-CC message, and no Transaction Identifier from the same MEP is allowed to be repeated within 1 minute.



• Unicast ETH-CC reply receipt

When a unicast ETH-CC message is received by a MEP (ETX-201) diagnostic flow termination function, it examines the TLVs returned in the unicast ETH-CC message, and declares the signal invalid if the TLVs do not match those sent in the corresponding exiting MEP ID and EVC ID.

• Continuity declarations

Loss of Continuity and Connectivity Mismatch states are declared by the ETH-CC mechanism.

Loss of continuity declaration

When the MEP receives the ETH-CC message a timer is set with a 3.5 seconds timeout. If the source does send another message during this period, the destination enters the loss of continuity state. Upon receipt of the ETH-CC message, the destination resets the timer to 3.5 seconds. Regarding the continuity check message, the destination check the EVC ID and the MEP ID. When the destination enters the loss of continuity state, it adds 4 to the Unavailable Seconds counter. The 3.5 second period is calculated as a sliding window.

Loss of continuity state is cleared after 3.5 seconds with at least 2 messages from the source. In this case the Unavailable Seconds counter is decreased by 4.

Connectivity mismatch declaration

If the source EVC ID is not equal to the destination EVC ID for 10 consecutive times, the destination enters a misconnection state.

Misconnection state is cleared after 10 consecutive reply messages with the correct EVC name from the source.

The Unavailable counter is maintained by the service according to the number of PM messages that did not receive replies. If a mismatch notification is received to the LB request, the frame is dropped and a reply message is not sent. This is why the service becomes unavailable (no reply) in case of mismatch and the unavailable counter is raised.

Performance Measurement

ETX-201 measures performance for 15-minute intervals. It also stores performance history data the last 24 hours (96 intervals). Table C-2 lists the PM counters supported by ETX-201.

C.5 RMON Statistics

In addition to the regular statistics collection, ETX-201 supports proactive SLA measurements per ETX-201 port, as per RMON-based RFC 2819. The device sends reports when one of the available counters (physical layer or OAM) rises above or drop below the set thresholds within the specified sampling period of time. These reports can be sent as SNMP traps to the defined network management stations or be written to the event log.

The following counters can be monitored:

• Dropped Frames

• Undersize Frames

• Oversize Frames

• Fragmented Frames

• Jabbers

• Frame Loss Ratio

1. Loosen the cover screw on the bottom of the AD plug to open it (see Figure 3).

2. Run your DC power supply cable through the removable cable guard and through the open cable clamp.

3. Place each DC wire lead into the appropriate AD plug wire terminal according to the voltage polarity mapping shown. Afterwards, tighten the terminal screws closely.

4. Fit the cable guard in its slot and then close the clamp over the cable. Tighten the clamp screws to secure the cable.

5. Reassemble the two halves of the AD plug and tighten the cover screw.

6. Connect the assembled power supply cable to the unit.

Note: You have to flip over the non-90-degree AD plug type by 180 degrees to insert it into the unit. After inserting it, verify that the blue (negative) wire is connected to the POWER and the brown (positive) wire is connected to the RETURN.

Figure 3. AD Plug Details

• Reversing the wire voltage polarity will not cause damage to the unit, but the internal protection fuse will not function.

• Always connect a ground wire to the AD plug’s chassis (frame) ground terminal. Connecting the unit without a protective ground, or interrupting the grounding (for example, by using an extension power cord without a grounding conductor) can damage the unit or the equipment connected to it!

• The AD adapter is not intended for field wiring.

Terminal BlockConnector

for DC Power Supply Connection

Supplement

Ignore this supplement if the unit is AC-powered.

Certain DC-powered units are equipped with a plastic 3-pin VDC-IN power input connector, located on the unit rear panel. Different variations of the connector are shown in 0Figure 1. All are functionally identical.

Supplied with such units is a kit including a mating Terminal Block (TB) type connector plug for attaching to your power supply cable.

Connect the wires of your power supply cable to the TB plug, according to the voltage polarity and assembly instructions provided on the following pages.

Figure 1. TB DC Input Connector Types Appearing on Unit Panels

Prepare all connections to the TB plug before inserting it into the unit’s VDC-IN connector.

Caution

Note

To prepare and connect the power supply cable with the TB Plug:

Note: Refer to 1Figure 2 for assistance.

1. Strip the insulation of your power supply wires according to the dimensions shown.

2. Place each wire lead into the appropriate TB plug terminal according to the voltage polarity mapping shown in 2Figure 3. (If a terminal is not already open, loosen its screw.) Afterwards, tighten the three terminal screws to close them.

3. Pull a nylon cable tie (supplied) around the power supply cable to secure it firmly to the TB plug grip, passing the tie through the holes on the grip.

4. Isolate the exposed terminal screws/wire leads using a plastic sleeve or insulating tape to avoid a short-circuit.

5. Connect the assembled power supply cable to the unit by inserting the TB plug into the unit’s VDC-IN connector until it snaps into place.

Figure 2. TB Plug Assembly

Figure 3. Mapping of the Power Supply Wire Leads to the TB Plug Terminals

• Reversing the wire voltage polarity can cause damage to the unit!

• Always connect a ground wire to the TB plug’s chassis (frame) ground terminal. Connecting the unit without a protective ground, or interruption of the grounding (for example, by using an extension power cord without a grounding conductor) can cause harm to the unit or to the equipment connected to it!

Warning

Note: Certain TB plugs are equipped with captive screws for securing the assembled cable’s TB plug to the unit’s VDC-IN connector (C and E types only). To secure the plug, tighten the two screws on the plug into the corresponding holes on the sides of the input connector as shown in 3Figure 4.

Figure 4. TB Plug with Captive Screws (optional)

To disconnect the TB plug:

1. If the TB plug is equipped with captive screws, loosen the captive screws (see 4Figure 4).

2. If the unit’s VDC-IN connector is type B, lift the locking latch (see 5Figure 1).

3. Pull out the TB plug carefully.

Always lift the locking latch of type B connectors before disconnecting the TB plug, to avoid damaging the TB plug.
