This object sets the number of seconds the RADIUS client waits for a response from a RADIUS server before considering the request unanswered, and its value must survive a device reboot. Administrators tune it to match network latency to the RADIUS server — too short a value triggers unnecessary retries and login delays for users authenticating via 802.1X or MAC authentication, while too long a value stalls failover to a backup server. For example, an admin might raise this toward 10 seconds if the RADIUS server sits across a slow WAN link and clients are seeing spurious authentication timeouts.
