swL2DevAlarmLinkChange
Module: DGS-3420-26SC-L2MGMT-MIB
OID (symbolic): DGS-3420-26SC-L2MGMT-MIB::swL2DevAlarmLinkChange
OID (numeric): 1.3.6.1.4.1.171.11.119.6.2.1.3.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determines whether or not to send a trap message when the link changes. If the object is enabled (3), the Link Change trap is sent by the device when any of its port links change. The device does not send the trap if this object value is disabled or in another state.
What is swL2DevAlarmLinkChange?
This INTEGER, when enabled(3), makes the switch send a trap whenever any port's link state changes, letting an admin get near-real-time alerts on cable pulls or link flaps instead of relying on polling.
