swL2DevAlarmLinkChange
Module: SW-DES3x50-L2MGMT-MIB
OID (symbolic): SW-DES3x50-L2MGMT-MIB::swL2DevAlarmLinkChange
OID (numeric): 1.3.6.1.4.1.171.11.2.1.3.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determine 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?
Controls whether the switch sends a trap whenever any port's link state changes up or down; admins enable(3) this so a management station gets immediate notification of a cable pull or link flap instead of relying on periodic polling.
