We are testing currently dot1x auth against FreeRADIUS/AD in the network. The vlans are dynamically assigned by FreeRADIUS on AD-group base. This works, but now the problem comes:
We wanted to add our ip-telephones which doesn't speak dot1x to the network so we created a voice-vlan on the interfaces. This still didn't solve our problems because our ip-telephone came in the guest-vlan.
the interface configuration is the following:
... ! interface ethernet 1/g7 spanning-tree portfast switchport mode general switchport general allowed vlan add 22 tagged dot1x guest-vlan 55 voice vlan 22 voice vlan auth disable ...
dot1x mac-auth-bypass also doesn't work because we have a guest vlan configured.
So my question is the following: How do I configure it on a Dell powerconnect 6248p so that my ip telephones will be on the correct vlan and still have my dot1x auth for users and still having a working guest vlan?
