This value sets the 802.1p priority tag, from 0 to 7, applied to the transmitted HVPLS OAM ping frames. An admin can raise it to ensure the OAM test frames are treated with the same or higher priority as production traffic on the VPLS instance, avoiding false negatives caused by queuing delay under this test's own low priority. For example, setting rsPingHVplsCtlPriority to 5 would tag the HVPLS OAM ping frames with priority 5 to mirror how voice traffic is normally marked on that service.
