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
