LACP/3/LAG_DOWN_REASON_EVENT

Message

LACP/3/LAG_DOWN_REASON_EVENT: The member of the LACP mode Eth-Trunk interface went down. (TrunkName=[STRING], PortName=[STRING], Reason=[STRING])

The member interface of an Eth-Trunk interface in static LACP mode went Down.

Parameter Name	Parameter Meaning
TrunkName	Name of an Eth-Trunk interface in static LACP mode
PortName	Name of the member interface of an Eth-Trunk interface in static LACP mode
Reason	Reason why the member interface of an Eth-Trunk interface in static LACP mode went Down

Operations on the local end or external events caused the member interface of an Eth-Trunk interface in static LACP mode to go Down.

Cause 1: The lower limit on the number of Eth-Trunk member links was not met.
Cause 2: The upper limit on the number of Eth-Trunk member links was not met.
Cause 3: The local member or Eth-Trunk interface was shut down.
Cause 4: The local member interface's rate changed.
Cause 5: The local member interface's simplex/duplex mode was changed.
Cause 6: Bit errors were detected on the local member interface.
Cause 7: The preemption delay timed out.
Cause 8: The receive timer expired.
Cause 9: The local Eth-Trunk interface's aggregation flag was set to false.
Cause 10: The E-Trunk went to the slave state.
Cause 11: The E-Trunk's IP address changed.
Cause 12: The remote and local system IDs were set to the same value.
Cause 13: The lower limit on the bandwidth of Eth-Trunk member links was not met.

Troubleshoot the fault based on the reasons listed in the log, as well as the LACP state and parameters of the local Eth-Trunk interface's member interfaces. For details, see the section "Checking the Configurations" in Configuration Guide - Configuring an Eth-Trunk Interface to Work in Static LACP Mode of the product document.
