What is swMSTPInstLastTopologyChange?
This OID reports how long ago, in hundredths of a second, this instance last detected a spanning tree topology change. Operators watch this to gauge network stability; a value that keeps resetting to near zero indicates a flapping link or a loop somewhere in the topology.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.10.120.100.2.2.2.3.1.21 snmpwalk -v2c -c public <target> DGS-6600-STP-EXT-MIB::swMSTPInstLastTopologyChange
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.10.120.100.2.2.2.3.1.21.1 snmpget -v2c -c public <target> DGS-6600-STP-EXT-MIB::swMSTPInstLastTopologyChange.1
