This value sets, in seconds, how long the client waits for a response from the RADIUS accounting server before considering the request timed out. Tuning it balances responsiveness against false timeouts on slower or congested links to the accounting server. For example, the default of 5 seconds is usually sufficient on a LAN, but an admin might raise it toward the 10-second maximum for a RADIUS server reached over a high-latency WAN link.
