Error Message Information Group rad_acct: Radius server <ip address> is responding
again (previously dead). Error Group acct: No active radius servers found. Id 106
Explanation
This message is seen if the radius-server deadtime 10 command is configured on the
access point.This command is configured to set an interval during which the access point does not
attempt to use servers that do not respond. Thus avoids the time needed to wait for a request to time
out before trying the next configured server. A Radius server marked as dead is skipped by
additional requests for the duration of the minutes unless all servers are marked dead. Configuring
dead time for 10 minutes means that the server cannot be used for 10 minutes.
Recommended Action You can disable this command if you want this log to disappear. Actually this
message is not really a major problem, it is just an informational log.
