Hammer, You are not way off, just that the same behavior is seen even if I add "sw mode access" and "sw noneg" on the Cat port. And no... it does not form a trunk with the router port either way, nothin in the "show int trunk". So it seems this access + voice vlan trick mentioned in the DSG does not work on the IOS version used in ProctorLabs.
