Field
Description
Tag
Name that identifies the IS-IS area.
VRF
VRF name.
System Id
Uniquely identifies a system within an area.
Interface
Interface from which the system was learned.
SNPA
SubNetwork Point of Attachment (SNPA): MAC address of the next-hop.
State
Adjacency state:
Init: Router is an IS and is waiting for an IS-IS hello message. IS-IS regards the neighbor as not adjacent.
Up: ES or IS is considered reachable
Holdtime
Number of seconds before this adjacency entry times out.
Type
Type of adjacency:
L1: Router adjacency for level 1 routing only
L2: Router adjacency for level 2 only
L1L2: Router adjacency for level 1 and level 2 routing
Protocol
Protocol through which the adjacency was learned.
Adjacency ID
Adjacency identifier.
Uptime
How long the adjacency has existed.
Area Addresses
Area addresses associated with the intermediate-system adjacencies.
IPv4/IPv6 address(es)
IP addresses of the ES or IS.
Topology
IPv4 and/or IPv6.
Protocols Supported
IPv4 and/or IPv6.
Adjacency advertisement
Restart: Suppress or Advertise.
