This section describes how to configure an Eth-Trunk interface, which can load-balance traffic between devices, increase bandwidth, and improve link reliability.
This section describes how to configure Layer-3 Eth-Trunk interfaces, Layer-2 Eth-Trunk interfaces, Eth-Trunk sub-interfaces, and Eth-Trunk interfaces in static LACP mode.
After creating an Eth-Trunk interface, add physical interfaces to the Eth-Trunk interface to increase link bandwidth, improve reliability, and carry out load balancing.
If an Eth-Trunk interface works in static LACP mode, you need to configure static LACP parameters. An Eth-Trunk interface in static LACP mode allows its members to implement M:N backup, which improves fault tolerance performance and reliability of the Eth-Trunk interface.
When the number of Up member links falls below the lower limit, the Eth-Trunk interface goes Down. Setting the lower limit ensures the minimum bandwidth of the Eth-Trunk interface.
To implement load balancing on an Eth-Trunk interface, configure a load balancing mode for the Eth-Trunk interface and assign load balancing weights to its member interfaces.
