aggregation priority value wins out. If two ports have the same aggregation priority, the system
compares their port numbers. The port with the smaller port number wins.
Setting the aggregation state of each member port
After the reference port is selected, the system with the lower system ID sets the state of each member port
in the dynamic aggregation group on its side as shown in
Figure 5 Set the state of a member port in a dynamic aggregation group
Meanwhile, the system with the higher system ID, being aware of the aggregation state changes on the
remote system, sets the aggregation state of local member ports the same as their peer ports.
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 also changes.
A port that joins a dynamic aggregation group after the selected port limit has been reached is placed in
the selected state if it is more eligible for being selected than a current member port.
