display isis peer

Use display isis peer to display IS-IS neighbor information.

Syntax

In standalone mode:

display isis peer [ statistics | verbose ] [ process-id ] [ standby slot slot-number ]

In IRF mode:

display isis peer [ statistics | verbose ] [ process-id ] [ standby chassis chassis-number slot slot-number ]

Parameters

statistics: Displays IS-IS neighbor statistics.

verbose: Displays detailed IS-IS neighbor information. Without 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. Without this argument, the command displays neighbor information for all IS-IS processes.

standby slot slot-number: Displays backup IS-IS neighbor information for a card. Without this option, the command displays IS-IS neighbor information. (In standalone mode.)

standby chassis chassis-number slot slot-number: Displays backup IS-IS neighbor information for a card on an IRF member device. The chassis-number argument specifies the ID of the IRF member device. The slot-number argument specifies the slot number of the card. Without this option, the command displays IS-IS neighbor information. (In IRF mode.)

Table 57: 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.
Peer local circuit ID	Circuit ID of the neighbor.
Peer circuit SNPA address	SNPA address of the neighbor.
Graceful Restart capable	The neighbor has the GR helper capability.
Restarting signal	RR flag.
Suppress adjacency advertisement	SA flag.
