Selecting a reference port
The local system (the actor) and the remote system (the partner) negotiate a reference port using the
following workflow:
1. Compare the system ID (comprising the system LACP priority and the system MAC address). The
system with the lower LACP priority value wins out. If they are the same, compare the system MAC
addresses. The system with the lower MAC address wins.
2. The system with the smaller system ID selects 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 wins out. If two ports have the same aggregation priority, the system
compares their port numbers. The port with the smaller port number wins.
Setting the aggregation state of each member port
After the reference port is selected, the system with the lower system ID sets the state of each member port
in the dynamic aggregation group on its side as shown in Figure 6 .

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.
