swDevAlarmTopologyChange
Module: DES3225G-MIB
OID (symbolic): DES3225G-MIB::swDevAlarmTopologyChange
OID (numeric): 1.3.6.1.4.1.171.11.24.1.3.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determine to send a trap or not when the switch topology was changed. 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 tranition, the device doesn't send the trap if this object value is disabled or other.
What is swDevAlarmTopologyChange?
Enables or disables sending a trap whenever the STP topology changes, i.e. when a configured port transitions between Learning/Forwarding/Blocking states. Enabling it lets an admin get notified of network topology instability without polling.
