Introduction

1 Introduction

This document shows an example of how to configure a Network Element (NE)for L1 Radio Link Bonding, using either Layer 1 Connection or the EthernetSwitch. For more detailed information, see Configuring an Ethernet Layer 1Connection, Reference [2].

The Ethernet Switch can be configured using Provider Mode or CustomerMode.

Note: The whole network needs to be configured using the same mode.

Note: To be able to change switch mode, the switch must be clean. Thismeans that only the default VLAN must be present, with no portmembers; xSTP must be disabled at switch level; and all switch portsmust be disconnected.

The following plug-in units are required:

• NPU3 B, NPU3 C, NPU3 D, or NPU1 C

• MMU2 D/H, MMU2 K, or MMU3 A

Figure 1 shows the alternatives for the configuration.

Figure 1 Configuration Alternatives

The configuration is done in two main steps:

• Dimensioning of the Packet Links and assigning them to a Radio LinkInverse Multiplexing for Ethernet (RL-IME) to create an RL-IME bondinggroup, see Section 6 on page 8.

3 Preparations

This section presents the preparations needed for a successful completionof the procedures in this instruction.

3.1 Additional Preparations

Consider the following additional preparations:

• Read through all applicable sections and make sure referenced documentsare available. All pages in MINI-LINK Craft are described in detail inMINI-LINK Craft User Interface Descriptions, Reference [4].

• Make sure you have access to the NE using MINI-LINK Craft. For moreinformation, see Accessing a Network Element, Reference [1].

Alternative Configuration Using Wizards

4 Alternative Configuration Using Wizards

It is possible to do parts of the L1 Radio Link Bonding configuration using thewizards in MINI-LINK Craft. To set up or modify a Layer 1 Connection, theLayer 1 Ethernet Wizard can be used instead of the manual procedure shownin Section 7 on page 9. To set up or modify WAN, LAN, VLAN, and switch ports,the Layer 2 Ethernet Wizard can be used instead of the manual proceduredescribed in Section 8 on page 10. LAG must be configured manually.

For more information on how to use the wizards, see Configuring an EthernetLayer 1 Connection, Reference [2] and Configuring an Ethernet Layer 2Connection, Reference [3].

5 Limitations

This document describes how to configure native Ethernet over multiple radiolinks and tasks related to this. It is also only an example showing WAN to LANconnection. When connecting to an Ethernet switch it is possible to connectWAN to WAN as well.

5.1 Packet Link

The Packet Link is the part of the radio link that transports native Ethernet,and it must be assigned to an RL-IME.

A radio link has a total capacity which is divided in E1 traffic and Packet Linkcapacity (native Ethernet). The relationship between the Packet Link size andthe number of E1s is managed by configuring the number of E1s. This canbe done in two ways:

• To specify a range of consecutive E1s starting from E1:1, set Number ofE1s to the desired number, see Example 1 in Figure 2. Unused E1s withinthis range (for example, not cross-connected) are not used for Packet Link.

• Reservation of individual E1s is done by setting Selected E1s underAdvanced settings, see Example 2 in Figure 2.

5.2 WAN Interfaces

Each connected RL-IME in an NPU3 B, NPU3C, NPU3D, or NPU1 C requires aWAN interface. A WAN interface is created when a Packet Link is connectedto an RL-IME. There is a maximum of seven WAN interfaces available forNPU3 B, NPU3D, and NPU3 C, and a maximum of 20 WAN interfaces for

Limitations

NPU1 C. If for example six WAN interfaces are used for an ETU3 or an ETU2 B,only one RL-IME can be used in an NPU3 B, NPU3 C, or NPU3 D.

5.3 Switch Ports

Each LAN and WAN interface in an NPU3 B, NPU3C, NPU3 D, or NPU1 Crequires a switch port when connected to an Ethernet switch. There are 10switch ports available for NPU3 B or NPU3 C, and NPU3 D, and 25 switchports available for NPU1 C.

5.4 RL-IME

NPU3 B, NPU3 C, and NPU3 D carry five RL-IMEs, that can be configuredaccording to the following:

• One RL-IME bonding group supporting a maximum of four Packet Links.

• One RL-IME bonding group supporting a maximum of two Packet Links.

• Three RL-IMEs supporting one single Packet Link each.

NPU1 C carries 20 RL-IMEs, that can be configured according to the following:

• Four RL-IME bonding groups supporting a maximum of four Packet Linkseach.

• Four RL-IME bonding groups supporting a maximum of two Packet Linkseach.

• Twelve RL-IMEs supporting one Packet Link each.
