Procedure 13-2.4: Configure service-multiplexed UNI to UNI mapping

- Overview

Use this procedure to configure communication between a service-multiplexed UNI and another UNI. See Figure 13-4, Service-multiplexing UNI-UNI.

The required UNI and NNI ports must have been previously configured using the procedures in this section.

Frames with CVLANs, or untagged frames, from all ingress UNIs, whether service-multiplexed or not, must be properly mapped at the service-multiplexed UNI port in order to egress the port. Users must use the map <cvlan> <svlan> command at the egress port to include the mapped CVLANs.

In order for L2 switching to occur properly in the UNI-to-UNI case, the service-multiplexed egress UNI’s VLAN include list must also include the port default VLAN (pvid [DVLAN]) of the ingress port. Users must use the vlan participation include <vlanid> command at the egress port to include the DVLAN.

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

From the Privileged EXEC mode, enter vlan database to enter the VLAN Config mode.


3

From your work instructions, determine the CVLANs and SVLANs required for this service.

For this example, CVLANs 10, 20, and 30; SVLANs 100, 200.

From the VLAN Config mode, use the vlan <vlanid> command to create any new CVLANs and SVLANs and assign an ID (Range: 2-3965). Example: (ALU Switching) (Vlan) # vlan 20.


4

Enter exit, then enter configure to enter the Global Config mode.


5

VLAN ID 1 is the port default VLAN ID (pvid [DVLAN]) and cannot be deleted, but can be changed using the vlan pvid <vlanid> command.

If you need to change the default port VLAN ID (pvid [DVLAN]) of a port, perform the following:

  1. Enter interface <port>, where <port> is the AID of the port having the pvid changed. Example: (ALU switching) (Config) # interface a-42.

  2. From the Interface Config mode, enter vlan pvid <vlanid>, where <vlanid> is the new default VLAN ID (DVLAN) for the interface port. Range: 1-3965, default is 1.

    Example: (ALU switching) (interface a-42) # vlan pvid 2.

  3. From the Interface Config mode for the port having the pvid changed, enter vlan participation exclude <vlanid>, where <vlanid> is the old pvid (DVLAN) (default 1).

    Example: (ALU switching) (interface a-41) # vlan participation exclude 1.


6

If not already performed, for each service-multiplexed UNI port, use the map <cvlan> <svlan> command to specify the outer SVLAN tag to use, based on an ingress packet’s CVLAN tag.

From the Interface Config mode, enter map <cvlan> <svlan> to specify the outer (SVLAN) tag to use, based on an ingress packet’s CVLAN tag.

Example: (ALU switching) (interface a-41) # map 10 100.

Note:

All mapped cvlan and svlan tags are automatically added to the interface’s vlan participation include list. All unmapped tags are filtered in both directions. Both the cvlan and the svlan must first have been created using the vlan <vlanid> command, except for the special case for cvlan=0 for mapping untagged or pritority-tagged packets.


7

When a port has service-multiplexing turned on, level 2 switching will occur based on the port's pvid (DVLAN), so a packet will only egress the destination port if that port's VLAN participation include list contains the ingress port's pvid (DVLAN).

As required, configure each egress UNI interface for participation in the specified DVLAN.

From the Interface Config mode for the UNI port, enter vlan participation include <vlanid>, where <vlanid> is the specified DVLAN.

Example: (ALU switching) (interface a-41) # vlan participation include 1.
