Module: DGS-3700-12-L2MGMT-MIB
OID (symbolic): DGS-3700-12-L2MGMT-MIB::swL2DevAlarmLinkChange

Node type: OBJECT-TYPE
Type: INTEGER

Description: This object determines whether or not to send a trap message when the link was changed. If the object is enabled(3), the Link Change trap is sent by the device when any of its ports link change. The device does not send the trap if this object value is disabled or other.
What is swL2DevAlarmLinkChange?
When set to enabled(3), the switch sends a trap whenever any port's link state changes up or down, so a monitoring system can alert on cable pulls or NIC failures without polling every port.
