This read-only value reports the traffic handling priority class actually negotiated with the UMTS network for this QoS profile. An admin cares because the negotiated priority determines how the carrier schedules this device's packets relative to other traffic during congestion, making it a quick way to confirm the requested priority tier was actually honored. For example, if a router configured for high-priority data traffic later shows a lower negotiated priority here, the admin knows the network downgraded the connection and can expect it to be more affected by congestion during busy periods.
