802.1x authentication failure

[Endwigast]

hi, i'm not sure if i'm posting this in the right category but here goes

i wanna use 802.1x on our network but can't seem to get it to work. i followed all the instruction on the web site. it says authentication failed. i'm pretty sure the radius works because i use that same radius for our vpn authentication.

btw i'm using 48 port 2950-EI

config

aaa new-model

aaa authentication dot1x default group radius

interface FastEthernet0/3

switchport access vlan 52

switchport mode access

no ip address

dot1x port-control auto

dot1x timeout reauth-period 1

dot1x max-req 10

dot1x reauthentication

radius-server host x.x.x.x auth-port 1812 acct-port 1813 key <password>

radius-server retransmit 3

am i missing something? thanks

Hello,

depending on your IOS version, you might have to issue the global command ´dot1x system-auth-control´ (this command is required for IOS versions later than 12.1(14)EA1)...

i forgot to copy that part of the config to my post but it is definitely there. i got 121-19.EA1c code running

Hello,

ok, the config looks all right then. Is there a firewall or some other filter active between the switch and the RADIUS server that might be blocking the ports 1812 and 1813 ?
