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.
