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.
Examples

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:
|
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. |
