WS-C3550 Radius doesn't authenticate

[jocileiaa]

Hello everyone.

I have a switch that I'm applying authentication with radius, but it doesn't work.
Checking the authentication logs I see the request arriving at high ports and not at 1812.

Please, does anyone have any ideas or parameters that can be adjusted in this configuration?

Follow the configuration:

radius-server host 192.168.120.108 auth-port 1812 acct-port 1813 key 7 XXXXXXXX

aaa authentication login default group radius local
aaa authentication enable default group radius enable
aaa authorization exec default group radius local

ip radius source-interface Vlan98

It is the IOS and model:

Cisco IOS Software, C3550 Software (C3550-IPSERVICESK9-M), Version 12.2(25)SEE2, RELEASE SOFTWARE (fc1)

Thank you.

Hi
Can you try adding this config please? If not working, can you share your authentication log?

aaa group server radius myradius
server 192.168.120.108 auth-port 1812 acct-port 1813
!
aaa authentication login default group myradius local
aaa authentication enable default group myradius enable
aaa authorization exec default group myradius local
