This object enables creating, deleting, and modifying a row in the MPLS priority mapping table using the standard RowStatus mechanism; the associated priority bitmap can be changed while the row is active, provided the new value doesn't overlap other rows for the same service. Admins use it to provision or remove a priority-to-pseudowire mapping entry. For example, an admin would set this to createAndGo(4) to add a new priority mapping row for a pseudowire requiring differentiated class-of-service treatment.
