I'm trying to test mac based authentication with my 2930f and clearpass and I simply cannot get the switch to authenticate via radius.
In the event viewer, I have lots of "RADIUS authentication attempt from unknown NAD x.x.x.x:1812 (where x.x.x.x is the ip address of the switch) as soon I plug a phone into port 1.
I have double checked the key on the switch, as well as the radius shared-secret on the device and they are _identical_.
snippet from switch;
aaa server-group radius "Clearpass" host 1.1.1.3
aaa accounting update periodic 5
aaa accounting network start-stop radius server-group "Clearpass"
aaa authentication port-access eap-radius server-group "Clearpass"
aaa authentication mac-based chap-radius server-group "Clearpass"
aaa port-access authenticator 1
aaa port-access authenticator 1 tx-period 10
aaa port-access authenticator 1 supplicant-timeout 10
aaa port-access authenticator 1 client-limit 3
aaa port-access authenticator active
aaa port-access mac-based 1
aaa port-access mac-based 1 addr-limit 2
The clearpass service i'm testing against is type radius, mac authentication template - authentication methos all MAC AUTH.
