As far i know you don't configure the port as trunk it
can be access and still support the IP phone and PC.
here is the example:
interface FastEthernet0/11
switchport access vlan 250
switchport mode access
switchport voice vlan dot1p
no ip address
dot1x port-control auto
spanning-tree portfast
!
interface FastEthernet0/12
switchport access vlan 250
switchport mode access
switchport voice vlan 100
no ip address
dot1x port-control auto
spanning-tree portfast
the config on fa0/11 says that voice will use the
native vlan and on fa0/12 it says it will use a
dedicated voice vlan.
you need to have to command switchport mode access
otherwise dot1x will not work, you will get an error
dot1x not supported on dynamic port.
thanks
