Associate a Port and MLT with an I-SID for ELAN
Shortest Path Bridging MAC (SPBM) supports Layer 2 Virtual Service Network (VSN) functionality where Switched UNIs are bridged over the SPBM core infrastructure.
Switched User Network Interface (S-UNI) allows the association of local endpoints to I-SIDs based on local port and VLAN together. With switched UNI, the same VLAN can be used on one port to create an endpoint to one I-SID, and on another port to create an endpoint to another I-SID.
Use the following procedure to associate a port and MLT with an I-SID.
About this task
You must configure Switched UNI.
Procedure
- In the navigation pane, expand .
 - Select ISID.
 - On the Service tab, select a row with the type configured as elan.
 - Select Switched Uni.
 - Select Insert.
 - Enter the VLAN ID in the Cvid field.
 - Select Port or Mlt to update the interface index in the IfIndex field.
 - Select Insert.
