Figure 35 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, changes the aggregation state of its ports accordingly.
When you aggregate interfaces in dynamic mode, follow these guidelines:
•
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.
•
Any member port attribute or class-two configuration change might affect the aggregation state of
link aggregation member ports and ongoing traffic.
•
In a dynamic aggregation group, when the aggregation state of a local port changes, the
aggregation state of the peer port also changes accordingly.
•
A port that joins a dynamic aggregation group after the Selected port limit has been reached is
placed in Selected state if it is more eligible for being selected than a current member port.
