show isis interface

Display Intermediate-System-to-Intermediate-System (IS-IS) interface configuration and status parameters (including adjacencies).

Syntax

show isis interface
show isis interface [l1|l2|l12] [home|remote]

Command Parameters

home: Displays the IS-IS interface information that the system configures in the home area.
[ l1 | l2 | l12 ]: Displays the interface information for the specified level: l1 (Level 1), l2 (Level 2), l12 (Level 1 and 2). The switch is a Level 1 router, which means it has only Level 1 links and can route within only one area. Level 1 routers route only within their assigned area and cannot route outside that area. Level 2 routers route between areas and toward other domains. Level 1/Level 2 routers route within an assigned area and between areas. Level 1/Level 2 routers maintain both a Level 1 Link State Database and a Level 2 Link State Database.
remote: Displays the IS-IS interface information that the system configures in the remote area.

Default

None

Command Mode

User EXEC

Command Output

The show isis interface command displays the following information:


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 IS-IS interface Level 1 metric.
ORIGIN	Indicates the origin of the IS-IS circuit configuration on the port, either manually configured through CLI or EDM, or dynamically configured through Auto-sense.
AREA	Indicates the type of area as home or remote.
AREA-NAME	Indicates the name of the area.
