Display IS-IS Logical Interfaces

Use the following procedure to display the Intermediate-System-to-Intermediate-System (IS-IS) logical interfaces configured on the switch.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display the IS-IS logical interfaces:

    show isis logical-interface [name | ipsec | shaper | mtu]
