I have a network with a cisco 4500 switch with phone and data vlan. If I hook my pc up directly to the switch I get a link light and an ip address. If I hook my cisco ip phone up to the wall jack, I get an ip address. When I hook my pc up to the phone when the phone is hooked up to the wall jack, my pc gets an ip address. But if I hook my pc directly to the wall jack, my pc does not even show it is connected. I have tested this on 3 different computers and I get the same result with this 1 wall jack.
Anyone have an suggestions?
