Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
Use this command to conrm that the neighbor adjacencies are operating correctly. If you suspect that they are
not, you can verify the specied area addresses of the routers by using the show isis neighbors command.
The following describes the show isis neighbors command shown in the following example.
Field Description
System Id The value that identies a system in an area.
Interface The interface, slot, and port in which the router was discovered.
State The value providing status about the adjacency state. The range is Up and Init.
Type This value displays the adjacency type (Layer 2, Layer 2 or both).
