is chosen. If two ports have the same aggregation priority, the system compares their port numbers.
The port with the smaller port number and the same attribute configurations as the aggregate
interface becomes the reference port.
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 as shown in Figure 3.

e of a member port in a dynamic aggregation group
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.
When you aggregate interfaces in dynamic mode, follow these guidelines:
• A dynamic link aggregation group preferably sets full-duplex ports as the Selected ports. The group
will set only one half-duplex port as a Selected port when either of the following conditions exist:
