Configure an SPBM Layer 2 Switched UNI on an MLT

About this task

To configure a Switched UNI on an MLT, you must create a Switched UNI I-SID, and map an MLT to the Switched UNI I-SID.

Note

When you configure Switched UNI, Spanning tree is disabled on all Switched UNI ports.

1. Enter MLT Interface Configuration mode:

   enable

   configure terminal

   interface mlt <1-512>

2. Enable S-UNI on MLT:
   flex-uni enable

   

   Note

   You cannot enable Switched UNI on EAPoL enabled interface.

3. Configure a Switched UNI Service Instance Identifier (I-SID):

   i-sid <1–16777215> [elan]

   This command automatically transitions you to the ELAN I-SID Configuration mode.

4. Add an MLT to a Switched UNI I-SID:

   c-vid <1-4094> mlt <1–512>

   

   Note

   You can run this command again to map a Switched UNI MLT to multiple I-SIDs.

5. Add untagged traffic to a Switched UNI I-SID:

   untagged—traffic mlt <1–512> [bpdu enable]

6. Display the Switched UNI information:

   show mlt i-sid

Example

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#mlt 10
Switch:1(config)#interface mlt 10
Switch:1(config-mlt)#flex-uni enable
Switch:1(config-mlt)#i-sid 100
Switch:1(elan:100)#c-vid 20 mlt 10
Switch:1(elan:100)#untagged-traffic mlt 10 bpdu enable

Switch:1(elan:100)#show mlt i-sid
