VOIP Trunk port with 802.1x

I am currently researching 802.1x port authenication. Our currently access layer switches are 3750 with PoE. The port are currently configured with 802.1q trunking (a voice and data vlan) and QOS enabled. IOS level of 12.1.19. When setting up 802.1x port it is requiring the port to be set to switchport mode access, removing the trunking and QOS settings. Is there a way to have 802.1q and 802.1x configured together and maint. QOS for voice on a 3750 PoE switch?

Re: VOIP Trunk port with 802.1x

Yes, you do set the port to swithport mode access, but you also specify the voice vlan for the phone to use and it shouldn't be affected by the dot1x authentication. You can also setup layer 2 QOS to trust the packets tagged by the phone using a built in auto qos macro, or you can define your own.
