This read-write Unsigned32 (0-3932159) sets the local CLI idle timeout, in seconds, the interval the system waits for user input before timing out the session, per the description. Admins tune this to balance security (auto-logging out an idle console session) against convenience for administrators who need longer thinking time between commands. For example, lowering this timeout on a shared console-access device reduces the window an unattended, still-logged-in session remains exposed.
