Table 30-83. show isis neighbors Command Example Fields
Field Description
System Id The value that identifies 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 valid values are Up and Init.
Type This value displays the adjacency type (Layer 2, Layer 2 or both), and.
Priority IS-IS priority advertised by the neighbor. The neighbor with highest priority becomes the
designated router for the interface.
Uptime Displays the interfaces uptime.
Circuit Id The neighbor’s interpretation of the designated router for the interface.
