swL2DevAlarmLinkChange
Module: SW-COMMON-MIB
OID (symbolic): SW-COMMON-MIB::swL2DevAlarmLinkChange
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.1.2.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determines to send a trap or not 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 doesn't send the trap if this object value is disabled or other.
What is swL2DevAlarmLinkChange?
This object controls whether the switch sends a Link Change trap whenever any of its ports' link state changes. Admins enable it so link up/down events, like a cable being unplugged or an uplink flapping, are reported to the monitoring system as they happen. Setting this to enabled(3) ensures that unplugging a port's cable generates an immediate SNMP trap rather than requiring a manual poll to notice the outage.
