View all Configured I-SIDs

Perform this procedure to view all the configured I-SIDs including their types, ports, and MLTs.

About this task

View all configured I-SIDs (both CVLAN and T-UNI). View also the I-SID types and the ports or MLTs that are assigned to each I-SID.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. View all configured I-SIDs. This command displays both CVLAN and T-UNI based I-SIDs.

    show i-sid

  3. View all T-UNI (Elan-Transparent) I-SIDs.

    show i-sid [elan-transparent]

  4. View information for a particular T-UNI I-SID.

    show i-sid [<1–16777215>]

  5. View all IS-IS SPBM I-SID information by I-SID ID:

    show isis spbm i-sid {all|config|discover} [vlan <2-4059>] [id <1–16777215>] [nick-name <x.xx.xx>]

Example
