Configuring the
LACP Port
Priority
LACP port priority determines which port is the backup port to another port
when the link to that port is down. The port with the lowest value has the
highest value, and is selected to join the link aggregation group first.
To configure the LACP port priority, perform the following procedure:
1. From the Advanced Config menu, select Trunk Config > Port Priority
Config.
The LACP Port Priority page opens, as shown in Figure 78.

3. Click Apply.
