3.8.5.1 Receiving a QosCounterLease Frame

On receipt of this request, a responder MUST set the Lease timer to expire after 5 minutes. If the timer is already running, it is restarted. If the Snapshot timer is not already running, it MUST be started as well, and set to expire after 1 second.

If a responder chooses to implement separate instances of the timers and counter history per requesting controller, it has to find the appropriate context based on the controller's MAC address, or create a new context if there is no context yet. The controller's MAC address is specified by the Real Source Address field of the Base header. If this field does not contain a unicast address, and the responder implements per-controller contexts, the frame MUST be ignored.

The Real Destination Address and Sequence Number fields of the Base header are not used in processing the QosCounterLease frame, and MUST be ignored.
