If you're looking for this via the GUI, follow:
Managed Network folder > Config > System > Profiles > AP > AP Group > select the relevant group and scroll down to see the ports

But you need to make a wired port profile first to apply to the ports, follow:
Managed Network folder > Config > System > Profiles > AP > AP Wired Port > create a new profile and away you go.
