I have reviewed your attachment. In that attachment there is error message that states
%RADIUS-4-RADIUS_ALIVE: RADIUS server [IP_address]:[int],[int] has returned.
A RADIUS server that previously was not responding has responded to a new request
%RADIUS-4-RADIUS_DEAD: RADIUS server [IP_address]:[int],[int] is not responding.
The server might not be available to serve request. Server has not responded to repeated requests.
Recommended Action: Check for the connectivity to server. Check if the RADIUS server is still active. If not able to debug the issue, copy the message exactly as it appears on the console or in the system log. Enter the show running-config command to gather data that might help identify the nature of the message.
