This read-write value sets the minimum time, in seconds, between refreshes of this MIB's cached data; a request within that window returns cached data instead of re-polling the switch. Admins raise it to reduce polling load on the ServerNet fabric during heavy monitoring, or lower it (down to the 5-second minimum) when they need fresher data at the cost of more polling overhead. It defaults to 60 seconds; setting it too low can hurt performance, while setting it too high risks stale data.
