Configurations made in Layer 2 aggregate interface view can take effect only on the aggregate

interface; configurations made on an aggregation member port can take effect only after the port is

removed from the aggregation group. For detailed information about link aggregation, refer to Link

Aggregation Configuration in this manual.

After you enable MSTP on a Layer 2 aggregate interface, the system performs MSTP calculation

on the Layer 2 aggregate interface but not on the aggregation member ports. The MSTP enable

state and forwarding state of each selected port in an aggregation group is consistent with those of

the corresponding Layer 2 aggregate interface.

Though the member port of an aggregation group does not participate in MSTP calculation, the

port still reserves its MSTP configurations for participating MSTP calculation after leaving the

aggregation group.
