Description: The MST Identifier MCID. The MCID is a digest of the VID to MSTID configuration table which determines the Base VIDs enabled for SPBV and SPBM.

What is ieee8021SpbTopIxDynamicEntryMCID?

The MST Configuration Identifier digest of the VID-to-MSTID mapping table, which determines which Base VIDs are enabled for SPBV/SPBM on this topology; two bridges must have matching MCIDs to form an SPB adjacency, so this is a key value to check when adjacencies won't come up.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.26.1.3.1.3
snmpwalk -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbTopIxDynamicEntryMCID

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.26.1.3.1.3.1
snmpget -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbTopIxDynamicEntryMCID.1
