Description: The ethernet address of the last bridge from which a Topology Change Notification packet was received.
What is bridgeTopologyChangeAddr?
This object reports the Ethernet address of the last bridge from which a Topology Change Notification packet was received. An admin uses this to identify which bridge in the network most recently triggered a spanning tree topology change, aiding root-cause investigation of instability. For example, repeatedly seeing the same source address here would point to that specific bridge as the source of recurring topology changes.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.19.1.8 snmpwalk -v2c -c public <target> ITOUCH-BRIDGE-MIB::bridgeTopologyChangeAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.33.19.1.8.1 snmpget -v2c -c public <target> ITOUCH-BRIDGE-MIB::bridgeTopologyChangeAddr.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> bridgeTopologyChangeAddr.1
