Does an Eth-Trunk support LACP priority preemption

An Eth-Trunk supports LACP priority preemption only in LACP mode. You can run the lacp preempt enable command to enable LACP priority preemption.

In LACP mode, when an active link fails, the system selects the link with the highest priority from backup links to replace the faulty one. After the faulty link recovers and the priority of the link is higher than that of the backup one, if LACP priority preemption is enabled, the link with a high priority replaces the link with a low priority and switches to active.

LACP priority preemption configuration at both ends of an Eth-Trunk must be the same.
