How do I set up a port as a trunk port? Reference materials are greatly appreciated.

The port would be set up as a trunk port so that all the traffic can reach it. After that, traffic for the IP addresses registered to the OSA card by TCP stacks on the mainframe will be delivered to their appropriate TCP stack, thus achieving whatever security access you've set up. You may want to use VLAN's in the network to further increase confidence in the isolation and security. You would need to work with your network folks to set up the VLAN numbers & IP ranges that would correspond to the various access levels you defined.
