Displaying IS-IS interface parameters

Use the following procedure to display the IS-IS interface parameters.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display IS-IS interface configuration and status parameters (including adjacencies):

    show isis interface [l1|l2|l12]

  3. Display IS-IS interface authentication configuration:

    show isis int-auth

  4. Display IS-IS interface timers:

    show isis int-timers

  5. Display IS-IS circuit level parameters:

    show isis int-ckt-level

Variable definitions

The following table defines parameters for the show isis interface command.

Variable

Value

[l1, l2, l12]

Displays the interface information for the specified level: l1, l2, or l12.

Job aid

The following sections describe the fields in the outputs for the IS-IS interface show commands.

show isis interface

The following table describes the fields in the output for the show isis interface command.

Parameter

Description

IFIDX

Indicates the interface index for the Ethernet or MLT interface.

TYPE

Indicates the type of interface configured (only pt-pt is supported).

LEVEL

Indicates the level of the IS-IS interface (Level 1 [default] or Level 2).

OP-STATE

Shows the physical connection state of the interface.

ADM-STATE

Shows the configured state of the interface.

ADJ

Shows how many adjacencies are learned through the interface.

UP-ADJ

Shows how many adjacencies are active through the interface.

SPBM-L1–METRIC

Indicates the SPBM instance Level 1 metric on the IS-IS interface.

show isis int-auth

The following table describes the fields in the output for the show isis int-auth command.

Parameter

Description

IFIDX

Shows the interface index for the Ethernet or MLT interface.

AUTH-TYPE

Shows the type of authentication configured for the interface. Types include:
