dot3adAggLinkUpNotification
Module: IEEE8023-LAG-MIB
OID (symbolic): IEEE8023-LAG-MIB::dot3adAggLinkUpNotification
OID (numeric): 1.2.840.10006.300.43.0.1
Node type: NOTIFICATION-TYPE
Description:
When aAggLinkUpDownNotificationEnable is set to 'enabled,' a Link Up notification is generated when the Operational State of the Aggregator changes from 'down' to 'up.' When aAggLinkUpDownNotificationEnable is set to 'disabled,' no Link Up notifications are generated. The notification carries the identifier of the Aggregator whose state has changed.
What is dot3adAggLinkUpNotification?
This notification is sent when a Link Aggregation Group transitions from down to up status, provided that link-up notifications are enabled. The notification includes the identifier of the aggregator that changed state, allowing management systems to track high-availability link recovery. An operator uses this to monitor failover events and confirm that redundant link groups are coming online after maintenance or failure.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' IEEE8023-LAG-MIB::dot3adAggLinkUpNotification snmptrap -v2c -c public <manager> '' 1.2.840.10006.300.43.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
