My computer running xp is connecting to an ip phone and is falling into a dot-1-x guest vlan instead of the vlan
assigned by the acs server. computer functions properly when directly connected to the switch with 802.1x

this is a 3750g device.

 config for port

 PC should be assigned vlan 1 by ACS

I TRIED different phones 79XX adn saw the same problem. sniffer traces showed no EAP messages on the phone traces.
