This object reports how many seconds a listed wireless client has been idle, i.e. not sending or receiving traffic through the access point. Admins use it to identify stale client associations that may need to be aged out, or to distinguish active users from ones who have wandered out of range but not yet disassociated. A high clientInfoTableIdletime value, such as 300 seconds, suggests that client session is likely to be dropped soon due to inactivity.
