RADIUS Server High Availability?

Unanswered Question
Jan 18th, 2010

Hi,

I have two RADIUS servers in my network (one to be the failover serv) and one of them has been having problems, the server is not getting down but the radius service is getting crashed. Don't know why the failover server doesn't respond the authentication for the users if the books said that this is something automatic.

Is there one command to allow the switch to recognize if the service is down in one of the radius servers and automatically use the other one to authenticate the users?.

tks

I have this problem too.
