4800G and 802.1x

[fierrann]

Hi guys.

i have a little problem for config my 802.1x and dynamic assignement vlan

i have a radius (acs cisco) and a 4800G

i do this :

#

domain default enable X

#

dot1x

dot1x timer supp-timeout 10

dot1x authentication-method eap

#

hwtacacs scheme Y

primary authentication IP

secondary authentication IP

primary authorization IP

secondary authorization IP

primary accounting IP

secondary accounting IP

key authentication xxxx

key authorization xxxx

key accounting xxxx

user-name-format without-domain

#

radius scheme Y

primary authentication IP

primary accounting IP

secondary authentication IP

secondary accounting IP

key authentication xxxx

key accounting xxxx

timer realtime-accouting 15

timer responses-timeout 5

user-name-format without-domain

retry 5

#

domain X

authentication default radius-scheme Y

authorization default radius-scheme Y

accounting default radius-scheme Y

authentication login hwtacacs-scheme Y

authorization login hwtacacs-scheme Y

accounting login hwtacacs-scheme Y

authentication lan-acces hwtacacs-scheme Y

authorization lan-acces hwtacacs-scheme Y

accounting lan-acces hwtacacs-scheme Y

acces-limit disable

idle-cut disable

self-service-url disable

accounting optional

i also config the guest vlan

i config interface :

#

interface GigabitEthernet1/0/1

undo jumboframe enable

stp edged-port enable

dot1x guest-vlan 10

undo dot1x handshake

dot1x port-method portbased

dot1x

when i plug on this interface, port go to forwarding state and few seconds later i have a "authentification failed" message...

what's wrong with my conf ?

thx !
