802.1x / dot1x Authentication, including Voice-Vlan and Guest-Vlan
 

Hello,
i have tried to configure a dot1x based Authentication.
With an single host including guest-vlan, everything works fine.

But i want to use an Avaya-IP-Phone (wich is every times authenticated or authenticates itself) and behind the Phone an Client.

Is there a possible solution? And unfortunately Switches are Ciscos. https://supportforums.cisco.com/4.5....ticons/sad.gif

i have just tried so...

interface GigabitEthernet0/4
switchport access vlan 121
switchport mode access
switchport voice vlan 200
authentication event fail action authorize vlan 99
authentication event server dead action authorize vlan 121
authentication event server alive action reinitialize
authentication host-mode multi-host
authentication order dot1x
authentication port-control auto
authentication periodic
authentication violation restrict
dot1x pae authenticator
dot1x timeout quiet-period 10
dot1x timeout tx-period 1
spanning-tree portfast

Thanks, for any possible solution!
