Procedure 13-1: Enable/Disable L2CP tunneling

- Overview

Use this procedure to enable/disable L2CP tunneling on the VLNC4x.

Layer 2 control protocol tunneling is denied if Ethernet Ring Protection (ERP), spanning tree, [fllig ]ow control or link OAM are enabled for the port. These must all be disabled before enabling layer 2 control protocol tunneling.

L2CP tunneling is enabled/disabled on a per-port basis. By default, no L2CP frames, for any protocol will be forwarded (disabled). When L2CP frame tunneling is enabled for an interface, all L2CP frames (that meet other user classification criteria) will be forwarded as user traffic.

This command must be operated on customer LAN/host ports where the tunnel originates/terminates, as well as on network ports that will carry the tunneled traffic. It also must be run on the network ports of intermediate nodes that carry the tunnel.

Refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide, for help on using CLI commands.

Step
 
1

For each node being provisioned, login to the VLNC4x.

Result:

The User EXEC prompt [(ALU switching)>] displays.

2

Enter the Global Config mode:

  1. From the User EXEC prompt, enter enable to enter the Privileged EXEC mode.

  2. From the Privileged EXEC prompt, enter configure to enter the Global Config mode.

3

From the Global Config mode, enter interface <interface-number>, to enter the Interface Config Mode where “interface-number” is the address for the port you are provisioning.

See Addressable Entities in the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide for addresses.

Example: (ALU Switching)(Config)# interface d2-1.

4

From the Interface Config Mode, enter l2cp-tunnel to enable L2CP tunneling on the interface.

Enter no l2cp-tunnel to disable L2CP tunneling on the interface.

5

Repeat this procedure for each node/port in the network that will carry the tunneled traffic.
