Figure 10 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.
When you aggregate interfaces in dynamic mode, follow these guidelines:
A dynamic link aggregation group preferably sets full-duplex ports as the Selected ports. The group
•
will set only one half-duplex port as a Selected port when either of the following conditions exist:
None of the full-duplex ports can be selected.
Only half-duplex ports exist in the group.
• To ensure stable aggregation and service continuity, do not change the operational key or attribute
configurations on any member port.
When the aggregation state of a local port changes in a dynamic aggregation group, the
•
aggregation state of the peer port also changes.
