TRUNK Configuration of LAN Switchports on a 1590

[championc1]

I am trying to use several of the LAN ports on a 1590 for AP's, so I want to configure the ports as TRUNKs

I am working with LAN Ports 5 thru 8

I created a Bridge Group, but I could only create a Vlan against the physical ports for creating Layer3 interfaces.  I then created Vlans which are assigned to another physical port in the bridge, and associated this to the Bridge Group

I this the way to achieve what I am trying to do, or how should I configure it ?

See screenshot attached for what I have created.

Thanks in advance
