Figure 4 Setting the state of a member port in a dynamic aggregation group
The system with the greater system ID can detect the aggregation state changes on the peer system.
The system with the greater system ID 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 chooses only full-duplex ports as the Selected ports.
• For stable aggregation and service continuity, do not change the operational key or attribute
configurations on any member port.
• When a member port changes to the Selected or Unselected state, its peer port changes to the
same aggregation state.
• After the Selected port limit is reached, a newly joining port becomes a Selected port if it is more
eligible than a current Selected port.
