Description: The total number of topology changes detected by this bridge since the management entity was last reset or initialized.
What is bridgeDomainTopologyChanges?
This OID counts the total number of topology changes detected by the spanning tree algorithm since the device was last rebooted or the statistics were last reset. Engineers monitor this counter to identify unstable networks plagued by link flapping or to detect which parts of the network are causing frequent recalculations. A rapidly increasing count is a red flag indicating link or device instability.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.18 snmpwalk -v2c -c public <target> ACMIB::bridgeDomainTopologyChanges
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.18.1 snmpget -v2c -c public <target> ACMIB::bridgeDomainTopologyChanges.1
