Introduction

What Is in This Chapter

This chapter describes the SPECTRUM Management Module for the AT & T StarLAN10 SmartHUB (herein referred to as the SmartHUB). It also provides SPECTRUM’s Model Type Name assigned to the SmartHUB. The modeltype name refers to the template used to specify device attributes, actions, and associations for the device models in SPECTRUM.

AT & T StarLAN10 SmartHUB Management Module

The SmartHUB Management Module provides all the information necessary to manage the SmartHUB using SPECTRUM. The SmartHUB Management Module includes a software emulation of the actual device attributes and functionality.

The SmartHUB is a single-slot, intelligent 10BASE-T Ethernet standards-based wiring hub which supports unshielded twisted pair (UTP), shielded twisted pair (STP) and fiber-optic cabling. The hub provides advanced network control and enhanced network security through the use of eavesdropping prevention and intrusion detection. Unauthorized protocol analyzers cannot eavesdrop; only assigned users access the network. The SmartHUB is designed to operate in a building or campus structured cabling environment.

The SPECTRUM SmartHUB Management Module manages SmartHUB devices using the SNMP network management agent and the Management Information Bases (MIBs), included with the management module.

SmartHUB Model Types

Introduction AT&T StarLAN10SmartHUB1-2 Management Module Guide

SmartHUB Model Types

The SmartHUB Management Module supports one SPECTRUM device model type: the Hub_ATT_SMART. The model type name for the hub appears on the text label at the bottom of the SmartHUB icon located in any SPECTRUM view. The SmartHUB management module also supports three major application model types, described below.

SPECTRUM management of a SmartHUB is based on common and device-specific applications. Two common applications (listed below with the associated SmartHUB firmware versions) are discussed in the

MIB II Applications Reference

.

A third single device-specific application, the ATT Chassis Application (ATT_App), is discussed in Chapter 5.

The view’s buttons and Frame and Octet pie charts provide the following information.

Frames Pie Chart

The pie chart shows the relative number of frames received in each of the five frame size bands since the hub was last initialized or the counters cleared.

Octets Pie Chart

The Octets pie chart shows the number of octets received and transmitted since the hub was last initialized. Below the pie chart, two fields show the number of octets as absolute integers and as a percentage of the total number of octets. The views accessed from each button are listed below.



Three buttons provide access to other performance views, described later in this chapter.

Clicking on the Errors button displays the Module Frame View, which contains the Frames pie chart.

Clicking on the Port Performance button displays the Frame Breakdown View, which contains the Ports Performance View.

Clicking on the Error Information button displays the Module Error View with two pie charts containing module error breakdown statistics.

Module Frame View

The Module Frame View is displayed by clicking on the Frame Information button in the Module Performance View. It contains the Frames pie chart and fields which explain the bound between pie chart segments.

The Frames pie chart shows the relative number of frames received in each of the five frame size bands since the hub was last initialized or the counters cleared. Below the pie chart, the absolute number of frames in each band is shown with the percentage that this represents of the total number of frames.

Frame Size 1 (through) 4 Bound The upper boundary for the appropriate quantization band. Together these fields set the size of each of the five bands. Band 5 has no upper limit. These fields can be adjusted to the width of the bands.

Ports Performance View

The Ports Performance View is displayed by clicking on the Port Performance button in the Module Performance View.

Port I/O Table

Double-clicking on any column entry displays the Port Performance View, which displays four graphs with frames and octets received and transmitted time statistics.

Frame Information

Port Performance

Error Information



The fields in the Port Frame Size table are described below.

PortThe index number of the port.

Frames RcvThe total number of frames of legal length received on this port that have not been corrupted in transmission. This number includes both frames received OK and those with an “Out of range length” field. It does not include frames received with Frame Too Long or Alignment errors or frames lost due to internal MAC sublayer errors, runts or short events.

These frames can be encoded and decoded by commonly available MACs and provide a measure of the network bandwidth. The approximate rollover time for this counter is 81 hours.

Frames TxThe number of authorized frames transmitted out of the port is displayed. Additional information on authorized frames is listed below:

• The port authorized type is SingleAddress and the destination address equals the port authorized MAC address. (See the Address Tracking View.)

• The port authorized type is Multiple or Hub.

If the port type is None, no frames are counted. The approximate rollover time for this counter is 73 hours.

Octets RcvA total number of octets received on the port. Both data and padding octets in the frames received successfully are counted. The approximate rollover time for this counter is 58 minutes.

Octets TxThe number of octets transmitted from the hub on this port is displayed. Both data and padding octets are counted. The approximate rollover time for this counter is 58 minutes.

Error EnergyThe total length (in bytes) of all error energy is displayed. This value is used to calculate network utilization. Double-clicking on any entry displays the Port Performance View for the selected port. This view contains four graphs displaying the Frames Rcv, Frames Tx, Octets Rcv and Octets Tx against time. There are also two buttons which accesses the Error Breakdown and Frame Breakdown pie charts.

NOTE

The Frame Breakdown View is similar to the Module Frame View described earlier, but the pie chart and fields apply to the selected port only, not to the complete hub.



Port Frame Size

Double-clicking on any table entry displays the Frame Breakdown View for the selected port.

This table shows the number of frames transmitted from each port by packet size bands. The packet sizes correspond to LLC data.

Clicking on the Port Errors button displays the Ports Errors View, described in the next section.

Port Errors View

The Port Errors View is displayed by clicking on the Port Errors button in the Ports Performance View. It contains the Port Errors Table, divided into two halves. Double-clicking on any entry displays the Error Breakdown View for the selected port. The Error Breakdown View is described in the next section.

PortThe port number is displayed. Also the index to the table.

Late CollThe number of times that a late collision was detected on this port is displayed. These are collisions later than 512 times into the transmitted packet. A late collision is counted twice, both as a Collision and as a Late Collision.

Short EventsThe number of fragments received on this port is displayed. Fragments are less than 96 -n bits long (or 32-n bits for older controllers) and indicate an external noise hit; that is, a problem on the network.

FrameTooLargeThe number of frames received through this port that were greater than 1518 octets long is displayed.

Large FragThe number of fragments received by this port is displayed. Large fragments are any frames greater or equal to 96 bits, but less than 512 bits (which includes runt frame). The fragment count also includes any other length frames in which the start frame delimiter was not present.

FIFO ErrorsThe number of packets received by this port with the transmission frequency (data rate) detected to be out of spec. The exact degree of error is unspecified and vendor specific.

Port Errors



CollisionsThe number of times the transmit collision state was entered, irrespective of how many ports are involved. This count is displayed in the entry for Port 1 only. Receive collisions are not counted.

Auto PartitionsThe number of times that the repeater automatically partitioned this port is displayed.

RuntsThe number of collision fragment, longer than a Short Event but shorter than a legal packet, detected on this port is displayed. Runts do not indicate a problem on the network.

Manchester ViolationsThe number of Manchester Code violations is displayed. Manchester encoding is a self-clocking signalling type. This type of encoding guarantees at least one transition in voltage for every bit sent.

Module Error View

The Module Error View is accessed by clicking on the Error Information button in the Module Performance View. This view is also accessed by opening the Port Performance View from zone d of the Chassis Device View’s Logical Port Icon and clicking on the view’s Errors button.

To use the trap for a purely “keepalive” function, a control (the Trap Count Contents Ctrl) is specified such that only the Hub ID (see the Chassis Configuration View) and the Hub Alias objects are included. The hub default is to send only these two objects.

NOTE

The AT&T SmartHUB sends the SNMP-defined Cold Start Trap whenever it is powered on or reset.

Events and Alarms

What Is in This ChapterThis chapter describes the events and alarms generated by the SmartHUB. Additionally, this chapter notes if an event is mapped to an identical alarm message, and provides corresponding probable cause messages.

SmartHUB Events and AlarmsEvents and alarms originate as generic Simple Network Management Protocol (SNMP) traps sent from the physical device. These traps, or unsolicited messages, are translated as SPECTRUM events and displayed in the Event Log. For more information on specific traps generated by each device, refer to RFC 1213, which is available through the Internet system. Also refer to the applicable MIB (Management Information Base) documentation for each specific device.

Variable data within messages is enclosed in brackets {}.

For each event/alarm listed in this chapter, the following information is included:

• The event code• The event/alarm message• Any probable cause message for the mapped alarm• Any recommended actions

Table 4-1 lists events and alarms supported by the AT & T StarLAN10 SmartHUB.

Application Views

What Is in This ChapterThis chapter describes the SmartHUB Management Module Application View. The Application View allows the user to view information for the applications supported by the hub. Each application appears as an icon in the Application View.

SmartHUB ApplicationsSPECTRUM management of a SmartHUB device is based on both common and device-specific applications.

The common application depends on the device’s firmware version. SmartHUB with 9.x firmware support the MIB-1 application (SNMP1_Agent) while a SmartHUB with 10.x firmware supports the MIB-II application (SNMP2_Agent). These applications and their sub-applications are described in the MIB II Applications Reference.

The device-specific application supported by both the 9.x and 10.x firmware is the AT&T Chassis Application (ATT_ChassisApp). The views and other information associated with this application are decribed in the remainder of this chapter.

Accessing the Application View

Application Views AT&T StarLAN10SmartHUB5-2 Management Module Guide

Self Test Capability View


Self Test Capability ViewThe Self Test Capability View is accessed by highlighting the ATT_ChassisApp icon and selecting the Self Test option from the Icon Subviews menu. It contains the following information below the header fields.

Hub Reset Time StampThe SystemUpTime (in milliseconds) when the hub was last reset. This value is recorded whenever the hub enters the START state as defined in the 802.3 repeater standard.

Reset HubSetting this field to Reset initializes the relay, port counters, and flags in a repeater. This auto partition function resets only the MPR chip.

Reset Hub SystemSetting this field to Reset initializes all resettable management counters and also initializes the hub. All hub parameters are reset to the default parameters. The Reset Hub System default is NoReset.

Execute Self Test 1Setting this field to PerformTest initiates the non-disruptive self test function. The test does not:

• Change the state of the hub nor management information• Inject packets onto any segments• Prevent the relay of any packets.

The results are shown in the Hub Health Data field, and a hub health trap is sent with the Health State and Health Data included.

NOTE

This action does not reset the hub management counters, nor does it affect the port control parameters. However, packets can be lost and the Hub Reset Time Stamp is zeroed.

NOTE

The value of non-resettable counters can change as a result of resetting, and packets can be lost.



Security Configuration View

Execute Self Test 2Setting this field to PerformTest initiates the disruptive self test function. The test:

• Resets the state of the hub without affecting management information• Does not inject packets onto any segments• May prevent the relay of packets.

The results are shown in the Hub Health Data field, and a hub health trap is sent with the Health State and Health Data included.

Hub Health StateThis field indicates the state of the hub. If a failure exists, the Hub Health Data provides more specific failure information.

Hub Health DataAn octet block containing information relevant to the operational state of the hub. The encoding of this data block is vendor-dependent. The contents of each byte are explained in the view.

Security Configuration View

The Security Configuration view is accessed by highlighting the Hub_ATT_SMART icon in any view or the ATT_ChassisApp icon in the Application View and selecting the Security option from the Icon Subviews menu. The fields are described below.

EavesdroppingThis field enables or disables the jamming of frames to non-destination ports on a hub basis. If “Other” appears, the function does not apply.

IntrusionEnables or disables filtering on a hub basis.

Intrusion AlarmEnables or disables alarming; the generation of intrusion violation traps on a hub basis, for the intrusion protection security feature.

Inband Sets StateIf Enabled, the hub permits SNMP SETs to be received over the network.

NOTE

SETs can only be changed via the RS232 port.



PasswordThis field is used to set a new community string (password) for which the SmartHUB allows SETs. The password is sent in SET packets in the Community Name field in the packet’s header (that is, it is not sent as an object).

Bad PasswordsThe number of times a SET was received over the network. This could also occur if the hub’s COM port displays a bad password.

Setting Admin MAC AddrThe source MAC address of the last SNMP SET packet processed by the hub.

Setting Admin IP AddrThe source IP address of the last SNMP SET packet processed by the hub.

Clicking on the Port Security button displays the Port Security View, described below.

Port Security View

This view is displayed by clicking on the Port Table button in the Security Configuration view. The Port Security Table displays the following information:


Intrusion AddressIf an intruder has been detected on this port, this field shows the source address of the intruder. A value of all 0s indicates that no intrusion is detected.

Ports Performance View

The Ports Performance View is displayed by clicking on the Port Performance button in the Module Performance View. The view’s tables and button are described below.

Port I/O Table

Double-clicking on any entry displays the Port Performance View which displays the frames and octets received and transmitted against time in four graphs. This Port Performance View also has two buttons leading to the Error Breakdown View and the Frame Breakdown View.


Frames RcvThe total number of frames of legal length received on the port that have not been corrupted in transmission. This number includes both frames received OK and those displaying “Out of range length”. It does not include frames received with Frame Too Long or Alignment errors or frames lost due to internal MAC sublayer errors, runts or short events.

These frames can be encoded and decoded by commonly available MACs and provide a measure of the network bandwidth. The approximate rollover time for this counter is 81 hours.

Frames TxThe number of authorized frames transmitted out of the port. Additional information on authorized frames is listed below:



Error Information

NOTE

The Frame Breakdown View is similar to the Module Frame View described earlier, but the pie chart and fields apply to the selected port only, not to the complete hub.




Octets RcvA total number of octets received on the port. Both data and padding octets in the frames received successfully are counted. The approximate rollover time for this counter is 58 minutes.

Octets TxThe number of octets transmitted from the hub on this port. Both data and padding octets are counted. The approximate rollover time for this counter is 58 minutes.

Error EnergyThe total length (in bytes) of all error energy is displayed. This value is used to calculate network utilization. Double-clicking on any entry displays the Port Performance View for the selected port. This view contains four graphs displaying the Frames Rcv, Frames Tx, Octets Rcv and Octets Tx against time. There are also two buttons which lead to the Error Breakdown and Frame Breakdown pie charts.

Port Frame Size

Double-clicking on any entry displays the Frame Breakdown View for the selected port. This view is similar to the Module Frame View described in Chapter 2, but the pie chart and fields apply to the selected port only, not to the entire hub.

This table shows the number of frames transmitted from each port (for example, to a workstation) by packet size bands. The packet sizes correspond to LLC data. The singular button field is described below.

Clicking on the Port Errors button displays the Port Errors View, which contains the Port Errors Table. This table is described below.

Ports Errors View

The Ports Errors View is displayed by clicking on the Ports Errors button in the Ports Performance View. It contains the Ports Errors Table; double-clicking on any entry displays the Error Breakdown View for the selected port. The Error Breakdown View is described in the next section.

PortThe port number, indexed to the table.

Port Errors



Late CollThe number of times that a late collision was detected on this port. These are collisions later than 512 times into the transmitted packet. A late collision is counted twice, both as a Collision and as a Late Collision.

Short EventsThe number of fragments received on this port. Fragments are less than 96-n bits long (or 32-n bits for non-conforming controllers) and indicate an external noise hit or problem on the network.

FrameTooLargeThe number of frames received through this port that were greater than 1518 octets long.

Large FragThe number of fragments received by this port. Large fragments are any frames greater than or equal to 96 bits, but less than 512 bits (which includes runt frames). The fragment count also includes any other length frames in which the start frame delimiter was not present.

FIFO ErrorsThe number of packets received by this port with the transmission frequency (data rate) detectably out of spec. The exact degree of error is unspecified and vendor specific.

CollisionsThe number of times the transmit collision state was entered, irrespective of how many ports are involved. This count is displayed in the entry for Port 1 only. Receive collisions are not counted.

Auto PartitionsThe number of times that the repeater automatically partitioned this port.

RuntsThe number of collision fragments that are longer than a Short Event but shorter than a legal packet. Runts do not indicate a problem on the network.

Manchester ViolationsThe number of Manchester Code violations. Manchester encoding is a self-clocking signalling type. That guarantees at least one transition in voltage for every bit sent.

Error Breakdown View

The Error Breakdown View can be viewed by double-clicking on any table entry in the Ports Error View (accessed from the Ports Performance View). The view displays two pie charts, with the same fields as the Ports Errors View but for the selected table entry only.
