... but what's the point of using VLAN unless the mainframe tcpip stacks are supporting vlans and the physical switches are aware of the VLANS, and on trunk ports? If he just connects on two access ports on the same subnet at least he'll get cable pull recovery - even if his z series tcpip stacks are vlan ignorant. David

That should work, until they can give you a port on another switch to eliminate the single point of failure. Mark Post
