Step1 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 out.
Step2 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 LACP 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 out.
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 3 .
