Parameters

statistics: Displays IS-IS neighbor statistics.

verbose: Displays detailed IS-IS neighbor information. If you do not specify this keyword, the command displays brief IS-IS neighbor information.

process-id: Displays IS-IS neighbor information for an IS-IS process specified by its ID in the range of 1 to 65535. If you do not specify this argument, the command displays neighbor information for all IS-IS processes.

Table 73: Command output

Field	Description
System Id	System ID of the neighbor.
Interface	Interface connecting to the neighbor.
Circuit Id	Circuit ID.
State	Circuit state.
HoldTime	Within the holdtime, if no hellos are received from the neighbor, the neighbor is considered down. If a hello is received, the holdtime is reset to the initial value.
Type	Circuit type: L1—Means the circuit type is Level-1 and the neighbor is a Level-1 router. L2—Means the circuit type is Level-2 and the neighbor is a Level-2 router. L1(L1L2)—Means the circuit type is Level-1 and the neighbor is a Level-1-2 router. L2(L1L2)—Means the circuit type is Level-2 and the neighbor is a Level-1-2 router.
PRI	DIS priority of the neighbor.
Area Address(es)	Area address of the neighbor.
Peer IP Address(es)	IP address of the neighbor.
Uptime	Time elapsed since the neighbor relationship was formed.
Adj Protocol	Adjacency protocol: IPv4 or IPv6.
Peer local circuit ID	Circuit ID of the neighbor.
Peer circuit SNPA address	SNPA address of the neighbor.
Adj P2P three-way handshake	Indicates whether the neighbor supports P2P three-way handshake.
Peer extended circuit ID	Extended circuit ID of the neighbor interface. This field is available when the neighbor supports three-way handshake.
Graceful Restart capable	The neighbor has the GR helper capability.
Restarting signal	RR flag.
Suppress adjacency advertisement	SA flag.
Local topology	List of topologies supported by the local interface.
Remote topology	List of topologies supported by the neighbor interface.
