User Guidelines
RADIUS servers configured with a test username and a non-zero deadtime
are tested periodically for liveness. Liveness of a server is determined by
sending an Access-Request to the server using a configurable dummy login. If
an Access-Reject is returned, the server is marked alive and is available for use
for authentication. The radius deadtime configured retries and timeouts are
applied. It is suggested that the configured values be the same as the normal
RADIUS values. If a RADIUS server fails to respond, it is marked dead.
Setting the deadtime to 0 disables liveness checks and configures the switch
to never mark the server dead.
