I was wondering how does a switch proceed to detect when one or several radius server is down.
If I leave only one radius server in a C3560-24PS (running with the lastest software version) and shut all services associated with my ACS4.2 through the web interface, I receive the following error logs:
13:55:31:%RADIUS-4-RADIUS_DEAD: RADIUS server x.x.x.x:1645,1646 is not responding.
13:55:31:%RADIUS-4-RADIUS_ALIVE: RADIUS server x.x.x.x:1645,1646 is being marked alive.
Anyone can explain me why a such ouput?
Thank you for your help!
