LACP preemption is enabled.
By default, LACP preemption is disabled.
NOTE
To ensure normal running of an Eth-Trunk, enable or disable LACP preemption at both ends of the Eth-
Trunk.
Step 4 Run:
lacp preempt delay delay-time
The LACP preemption delay is set.
By default, the LACP preemption delay is 30 seconds.
NOTE
If both devices of an Eth-Trunk use different preemption delays, a longer preemption delay is used.

2.6.2.9 (Optional) Setting the Timeout Interval for Receiving LACPDUs
Context
If the Eth-Trunk on the local device cannot detect a self-loop or fault that occurred on a member
interface in the LAG on the remote device, data on the local device is still load balanced among
original active interfaces. As a result, data traffic on the faulty link is discarded.
After the timeout interval at which LACPDUs are received is set, if a local member interface
does not receive any LACPDUs within the configured timeout interval, the local member
interface becomes Down immediately and no longer forwards data.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
Step 3 Run:
lacp timeout { fast [ user-defined user-defined ] | slow }
The timeout interval at which LACPDUs are received is set.
By default, the timeout interval at which an Eth-Trunk receives LACPDUs is 90 seconds.
