Figure 10 Setting the state of a member port in a dynamic aggregation group
The system with the higher system ID is aware of the aggregation state changes on the remote system. The
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 chooses full-duplex ports as the Selected ports. The
group chooses only one half-duplex port as a Selected port when either of the following conditions
exist:
{
None of the full-duplex ports can become Selected ports.
{
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.
