Procedure 13-2.5: Configure a new NNI to participate with existing service-multiplexed mappings

- Overview

Use this procedure to configure a new NNI port on the VLNC4x for participation with existing service-multiplexed mappings. If no mappings currently exist and you just want to create an NNI, refer to Procedure 13-2.1: Configure an NNI on the VLNC40/42.

When double VLAN tagging is enabled on an interface it becomes a service provider NNI port. Ports without double VLAN tagging enabled become customer UNI ports. Double VLAN Tunneling may not be enabled on a port where service-multiplexing is enabled. When service-multiplexing is enabled on any port on the circuit pack, then only d-group ports may have double VLAN tagging enabled.

This procedure assumes that the existing mappings will be used for the newly created NNI.

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

Step
 
1

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


2

Enter configure to enter the Global Config mode.


3

From your work instructions, determine which ports are NNI ports.


4

From the Global Config mode, enter interface <interface-number> to enter the Interface Config Mode, where “interface-number” is the address for the port (NNI) on which you will enable double VLAN tagging.

Example: (ALU Switching)(Config)# interface d2-3.


5

From the Interface Config mode, enter mode dvlan-tunnel on the selected NNI port. Example: (ALU Switching)(interface d2-4) # mode dvlan-tunnel.


6

For correct egress behavior of the NNI, vlan tagging of the UNI PVID and SVLAN(s) is required at the NNI. In addition to vlan tagging, vlan participation include of the UNI PVID and SVLAN(s) is required at the NNI.

In order for ingress filtering at the NNI to occur properly, the NNI’s vlan participation include list must include all SVLANs that can ingress into the NNI.

Perform the following:

  • Configure vlan tagging to enabled for each NNI interface in the default pvid (DVLAN) and SVLANs.

    From the Interface Config mode for the NNI port, enter vlan tagging <vlanid>, where <vlanid> is the specified DVLAN or SVLAN. Repeat for each <vlanid> being included.

    Example: (ALU switching) (interface d2-3) # vlan tagging 100.

  • Configure each NNI interface for vlan participation in the specified DVLAN and SVLAN.

    From the Interface Config mode for the NNI port, enter vlan participation include <vlanid>, where <vlanid> is the specified DVLAN or SVLAN. Repeat for each <vlanid> being included.

    Example: (ALU switching) (interface d2-3) # vlan participation include 100.
