SRX - Want to configure L3 dot1q trunk port + access ports into trunked vlans.

My current setup has an SRX with a link into an aggregation switch via a single trunk port. I would like to configure and use the other interfaces on the SRX as layer2 access ports that can be in the same vlan(s) as the ones on the trunk.
