Table 22: Command output

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.
SPSource ID	Shortest path source identifier uniquely identifies the device as a multicast source in an SPBM VSI.
SPSource mode	SPSource ID creation method: Static—The SPSource ID is manually configured. Dynamic—The SPSource ID is dynamically assigned by ISIS-SPB.
Agreement mode	AP mode: Both—AP is enabled for both unicast and multicast FDB entries. The device issues a unicast or multicast FDB entry to the FIB for forwarding traffic only if it has reached an agreement with the neighbor. Multicast—AP is enabled only for multicast. The node forwards multicast traffic only after the two ends reach a strict agreement. However, the node forwards unicast traffic unconditionally. Off—AP is disabled. Digests are exchanged but a match is not required.
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.
B-VLANs	B-VLANs configured on the device.
