What is mstpRootInformationRootAddress?
This read-only string reports the MAC address of the bridge elected as root for a specific MST instance, which can differ from the overall CIST root reported at instance 0. An admin compares root addresses across instances to see whether load is genuinely being split across different root switches. For example, seeing a different MAC address at instance 1 than at instance 0 confirms that a separate switch was elected root specifically for the VLANs mapped into instance 1.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2882.2.1.1.4.8.1.1.2 snmpwalk -v2c -c public <target> COMTROL-ES8510-MIB::mstpRootInformationRootAddress
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2882.2.1.1.4.8.1.1.2.1 snmpget -v2c -c public <target> COMTROL-ES8510-MIB::mstpRootInformationRootAddress.1
