Usage
Use this command to confirm that the neighbor adjacencies are operating correctly. If you suspect that
Information
they are not, you can verify the specified area addresses of the routers by using the
command.
(OPTIONAL) Displays detailed information about neighbors.
(OPTIONAL) Identifies the interface type slot/port as one of the following:
•
For a Gigabit Ethernet interface, enter the keyword
the slot/port information.
•
For a Port Channel interface, enter the keyword
number:
C-Series and S-Series Range: 1-128
E-Series Range: 1 to 32 for EtherScale, 1 to 255 for TeraScale and 1 to 512 for
ExaScale.
•
For a SONET interface, enter the keyword
information.
•
For a 10-Gigabit Ethernet interface, enter the keyword
followed by the slot/port information.

Description
The value that identifies a system in an area.
The interface, slot, and port in which the router was discovered.
The value providing status about the adjacency state. The valid values are Up and
Init.
This value displays the adjacency type (Layer 2, Layer 2 or both).
IS-IS priority advertised by the neighbor. The neighbor with highest priority becomes
the designated router for the interface.
Displays the interfaces uptime.
The neighbor's interpretation of the designated router for the interface.
