Hi ,

I am having radius authentication issue. The issue occured after changing ACS Server key. now even i have corrected the key but still authentication issue exist.

I have verified ACS server connectivity with test command which is sucssefull but when i do remotely ssh to switch, it failed with unknow reason and no logs appeared at ACS server...

Here is my configurations...and debug... I would appreciate if you can suggest... the solution...

aaa new-model
aaa group server radius networks
server 192.168.255.101 auth-port 1812 acct-port 1813
!
aaa group server radius SNAC
server 192.168.44.33 auth-port 1812 acct-port 1813
server 192.168.224.14 auth-port 1812 acct-port 1813
!
aaa authentication login default local
aaa authentication login conslog local
aaa authentication login networks group radius local
aaa authentication dot1x default group SNAC
aaa authorization exec default group radius if-authenticated
aaa authorization network default group radius
aaa accounting exec default start-stop group radius

radius-server host 192.168.44.33 auth-port 1812 acct-port 1813 key 7 06222D12424F0A

Hi Nadeem,

do you have any key configured in ACS for network device group in which this device is a entry? If yes, please update that as well.

If still face the same issue, please provide the following:-

1. debug aaa authentication

2. debug radius

thanks,

Vinay
