Can I Add Interfaces with Different Bandwidths to an Eth-Trunk?

For S switches:

In earlier versions of V200R011C10, interfaces with different rates cannot join the same Eth-Trunk. In V200R011C10 and later versions, interfaces with different rates can join the same Eth-Trunk by running mixed-rate link enable.

However, when an Eth-Trunk performs load balancing calculation, the interface rate cannot be used as the calculation weight. When interfaces with different rates are added to the same Eth-Trunk, traffic is evenly load-balanced on all the links. Therefore, the bandwidth of member interfaces is calculated by the minimum rate of the member interfaces in the Eth-Trunk. For example, when a GE interface and a 10GE interface are added to the same Eth-Trunk, the rate of the GE interface is used in the calculation and the bandwidth of the Eth-Trunk is 2G.

For CE switches:

In earlier versions of V200R002C50, interfaces with different rates cannot join the same Eth-Trunk.

In V200R011C10 and later versions, interfaces with different rates can join the same Eth-Trunk in LACP mode.

To enable interfaces operating at different rates to forward traffic after they are added to an Eth-Trunk in LACP mode, run the lacp mixed-rate link enable command.

And the distribute-weight command can be used to configure the weight of load balancing for a member interface.

For AR routers:

The member interfaces in an Eth-Trunk interface must be an interface with the same Ethernet type and rate.
