Setting the Link Aggregation Mode to LACP

Context

In LACP mode, you must manually create an Eth-Trunk and add interfaces to the Eth-Trunk. However, active interfaces are selected through LACP negotiation, which is flexible.

Procedure

Run system-view
The system view is displayed.
Run interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
Run mode lacp
The Eth-Trunk is configured to work in LACP mode.

By default, an Eth-Trunk works in manual mode.

Before configuring an Eth-Trunk, ensure that both devices use the same working mode.

If an Eth-Trunk interface has member interfaces, you can switch the Eth-Trunk interface's working mode between manual mode and LACP mode. However, if the Eth-Trunk interface is added to an E-Trunk, you cannot change its working mode.

Configuration Tips

To delete existing member interfaces, run the undo eth-trunk command in the interface view or the undo trunkport interface-type interface-number command in the Eth-Trunk interface view.
