Description: In an MSTP Bridge, the CIST Regional Root Identifier parameter, i.e., the Bridge Identifier of the current CIST Regional Root.
What is ieee8021MstpCistRegionalRootIdentifier?
The Bridge Identifier of the current CIST Regional Root — the bridge acting as root for this whole MSTP region — letting you confirm which switch this bridge currently considers the top of its region's spanning tree.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.1.1.4 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistRegionalRootIdentifier
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.1.1.4.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistRegionalRootIdentifier.1
