reference port?
Meanwhile, the system with the higher system ID, which has identified the aggregation state changes on
the remote system, sets the aggregation state of local member ports as the same as their peer ports.
NOTE:
To ensure stable aggregation state and service continuity, do not change port attributes or class-two
configurations on any member port.
In a dynamic aggregation group, when the aggregation state of a local port changes, the aggregation state of
the peer port changes.
A port that joins a dynamic aggregation group after the Selected port limit has been reached will be placed in
the Selected state if it is more eligible for being selected than a current member port.
