Field | Description |
---|---|
Area address | ISIS-SPB area address of the device. |
System ID | System ID of the device in the ISIS-SPB area. |
System control address | Multicast destination for ISIS-SPB protocol packets. |
System name | Hostname configured with the is-name command. |
Bridge priority | SPBM bridge priority of the device. In conjunction with the system ID, the SPBM bridge priority forms the SPBM bridge ID. The SPBM bridge ID is a tie-breaker used in the ECT algorithms for choosing shortest paths. |
SPSource ID | Shortest path source identifier uniquely identifies the device as a multicast source in an SPBM VSI. In conjunction with the I-SID, the SPSource ID forms the multicast address of the device in an SPBM VSI. |
SPSource mode | SPSource ID creation method:
|
Agreement mode | AP mode:
|
B-VLANs | B-VLANs configured on the device. |
MCID information | Local 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. |
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. |
