• Choosing a reference port

• Setting the aggregation state of each member port

Choosing a reference port

The local system (the actor) and the remote system (the partner) negotiate a reference port by using the

following workflow:

1. The systems compare the system ID (which comprises the system LACP priority and the system MAC

address). The system with the lower LACP priority value is chosen. If they are the same, the systems

compare the system MAC addresses. The system with the lower MAC address is chosen.

2. The system with the smaller system ID chooses the port with the smallest port ID as the reference

port. A port ID comprises a port aggregation priority and a port number. The port with the lower

aggregation priority value is chosen. If two ports have the same aggregation priority, the system

compares their port numbers. The port with the smaller port number is chosen.

Setting the aggregation state of each member port

After the reference port is chosen, the system with the lower system ID sets the state of each member port

in the dynamic aggregation group on its side.
