Description: The Bridge Identifier for the CIST.
What is ieee8021MstpCistBridgeIdentifier?
The Bridge Identifier (priority plus MAC address) this bridge uses for the Common and Internal Spanning Tree (CIST), the baseline spanning tree instance that always exists in an MSTP region — compare this across switches to see which one wins root election for the CIST.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.1.1.2 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistBridgeIdentifier
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.1.1.2.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistBridgeIdentifier.1
