Common use of Field Description Clause in Contracts

Field Description. 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. display spbm summary‌ Use display spbm summary to display the SPBM digest. Any view network-admin network-operator # Display the SPBM digest. <Sysname> display spbm summary Summary information for SPBM Area address : 00.0000 System ID : 0011.2200.0001 System control address : 0180-c200-002e System name : spb-1 Bridge priority : 32768 SPSource ID : 200 SPSource mode : Static Agreement mode : Both MCID information: Format selector : 0 Region name : spb Revision level : 0 Configuration digest : 0x0253c1480d244e443b21e7c364d6e2a7 B-VLANs : 1-10, 100-200 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. display spbm unicast-fdb‌ Use display spbm unicast-fdb to display SPBM unicast FDB entries. display spbm unicast-fdb [ b-mac mac-address | b-vlan vlan-id | system-id system-id ] [ count ] Any view network-admin network-operator b-mac mac-address: Specifies a B-MAC address in H-H-H format. You can omit the consecutive 0s at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001. If you do not specify a B-MAC, the command displays unicast FDB entries for all B-MACs.
