Figure 62 Setting 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.
NOTE:
• A dynamic link aggregation group preferably sets full-duplex ports as the Selected ports, and will set
one, and only one, half-duplex port as a Selected port when none of the full-duplex ports can be
selected or only half-duplex ports exist in the group.
• To ensure stable aggregation state and service continuity, do not change port attributes or class-two
configurations on any member port.

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.
