A check in a box indicates the port is a member of the trunk. No check
means the port is not a member. A port trunk can contain up to eight
ports.
5. Change the Trunk Status from Disable to another setting. The choice
in the status field are the following:
Active - The specific aggregator will broadcast and respond to
LACPDU (LACP Data Unit) packets. This setting enables
the LACP feature for the trunk.

packets, but it will respond to them. This setting disables the LACP
feature for the trunk.
Manual - Enables static port trunking and disables the LACP
feature for the trunk.
Disable - Disables the static port trunk and disables the LACP
feature for the trunk.
