Configuring Radius Health Check
The RADIUS health-check mechanism allows a WLAN controller to determine if a RADIUS
server is available for authentication process. If the server is not available, a new server is
selected and incoming user authentication requests are forwarded to this server. This
enhances the efficiency of user authentication. RADIUS server health-check is enabled by
default and starts the health check when the first server (IP) is configured in a radius profile.
There are two parameters to be used in the radius server health-check — duration and
retries.
• The duration is the time the health-check feature waits for a reply from a RADIUS
server. It is also the time when the check on the next server happens. The default duration
is 3 seconds.
• The retries specifies the maximum number of health-check messages sent to check
the health status of a RADIUS server before marking a server as dead.
Health check interval value is configured during Radius servers configuration. RADIUS servers
are grouped into a profile, called the radius-profile. For more informaiton, see
RADIUS server
