swL2DevAlarmLinkChange
Module: DES3016-L2MGMT-MIB
OID (symbolic): DES3016-L2MGMT-MIB::swL2DevAlarmLinkChange
OID (numeric): 1.3.6.1.4.1.171.11.63.10.2.1.4.3
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?
Controls whether the switch emits an SNMP trap whenever any port's link state changes; setting it to enabled(3) turns the trap on, while disabled(2) or other(1) suppresses it. Operators typically enable this so a NOC gets immediate notification of a flapping uplink or an unplugged cable instead of only discovering it during the next poll.
