This read-only value reports outgoing bandwidth currently allocated to active QoS Class 2 connections on this port, the in-use complement to lportOutVAvailbwQoS2. An admin tracks this the same way as the class-1 equivalent but for whatever traffic type is assigned to class 2, watching for growth trends that indicate approaching the class's total reserved capacity. For example, a steady rise in lportOutAllocbwQoS2 as more interactive-video circuits get added to this port signals the admin should plan to increase lportAtmDataRateQoS2 before the class-2 reservation is fully consumed.
