I am configuring RADIUS authentication on my switches but it does not work and I don't know why.
My configuration is pretty straightforward :
aaa new-model aaa group server radius RADIUS-ACTIF server x.x.x.x auth-port 1812 acct-port 1813 server y.y.y.y auth-port 1812 acct-port 1813 ip radius source-interface Vlan10 deadtime 1 aaa authentication attempts login 5 aaa authentication password-prompt Secured-Password: aaa authentication username-prompt Secured-Username: aaa authentication login default local aaa authentication login RADIUS-ACTIF group RADIUS-ACTIF local aaa authentication enable default enable aaa authorization exec default group RADIUS-ACTIF local aaa session-id common line vty 0 4 login authentication RADIUS-ACTIF
The thing is : I can't see anything happening on the "Failed Attempts" on my ACS Server. There are no logs of my attempts at authentication.
ACS server is reachable via ping from my switches. I have tried to test the RADIUS access with the test command : I get the User rejected feedback after less than 2/3 seconds, so I am thinking that I can access the RADIUS but I get blocked even before submitting my credentials. It's a very strange behavior.
Does anybody has an idea as to why this would happen?
I should also say that the exact same configuration is working on one switch (on a different IP plan though.
