Module: FOUNDRY-SN-SWITCH-GROUP-MIB
OID (symbolic): FOUNDRY-SN-SWITCH-GROUP-MIB::snVLanByPortCfgStpTimeSinceTopologyChange
OID (numeric): 1.3.6.1.4.1.1991.1.1.3.2.7.1.15
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: The time (in hundredths of a second) since the last time a topology change was detected by the bridge entity.
What is snVLanByPortCfgStpTimeSinceTopologyChange?
This OID holds the elapsed time since the last spanning tree protocol detected a network topology change on a VLAN port. The spanning tree prevents network loops by selectively disabling ports. An operator would check this to understand when the network structure last changed and how long ago loop prevention was triggered.
