swL2DevAlarmTopologyChange
Module: DGS3224-L2MGMT-MIB
OID (symbolic): DGS3224-L2MGMT-MIB::swL2DevAlarmTopologyChange
OID (numeric): 1.3.6.1.4.1.171.11.101.3.2.1.3.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determines whether or not to send a trap message when the switch topology changes. If the object is enabled(3), the topologyChange trap is sent by the device when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. For the same port transition, the device does not send the trap if this object value is disabled or other.
What is swL2DevAlarmTopologyChange?
Controls whether the switch sends a topologyChange trap whenever a configured port transitions between Spanning Tree states (e.g. Learning to Forwarding, or Forwarding to Blocking). An admin enables this to get notified of STP topology churn that could indicate a flapping link or a loop.
