Table 21: Command output
Field | Description |
---|---|
System ID | System ID of the neighbor. |
Port | Interface connected to the neighbor. |
Circuit ID | Circuit ID of the link connected to the neighbor. |
State | State of the adjacency with the neighbor:
|
Holdtime | Adjacency hold time. The adjacency hold time equals the ISIS-SPB hello interval multiplied by the hello multiplier. The device removes the adjacency with the neighbor if it does not receive hello packets from the neighbor within the hold time. The device maintains the adjacency with the neighbor if it receives a hello packet from the neighbor before the hold time expires. |
Peer information | Neighbor information. |
Local information | Information about the local SPBM node. |
Host name | Symbolic hostname of the SPBM node. If the node is not assigned a symbolic hostname, this field displays its system ID. |
Circuit ID | Circuit ID of the link. |
Cost | Link metric value. |
MCID information | Primary MST configuration identifier. It contains a digest of B-VLAN to MSTI mappings on the SPBM node. SPBM nodes must have the same MCID for the same I-SID. |
Aux MCID information | Auxiliary MCID of the SPBM node. |
Format selector | Format selector. It is fixed at 0 for IEEE 802.1aq SPB. |
Region name | MST region name. |
Revision level | MST region revision level. The default level is 0. You can use the revision-level command to change the revision level. |
Configuration digest | The SPBM node's digest of B-VLAN to MSTI mappings. |
AP information | AP information advertised on the adjacency. This field displays N/A if the SPBM node has not advertised AP information. |
AN | Agreement number advertised by the SPBM node. |
DAN | Discarded agreement number advertised by the SPBM node. |
Valid | Validity of the advertised AP digest:
|
Format identifier | Digest format identifier. |
Format capabilities | Digest format options. |
Convention identifier | Loop-free forwarding rules:
|
Convention capabilities | Loop-free forwarding rule conventions supported by the SPBM. |
Edge count | The sum modulo 216 of all edges in the SPB topology. Each point-to-point physical link is counted as two edges. This field provides one component of the agreement digest for detecting topology mismatches. |
Topology digest | Two neighbors must have the same topology digest to reach an agreement. |
