Description: This table may be used for MPLS PSNs if there is a need to hold multiple PW, each with different COS, for the same user service (port + PW VLAN). Such a need may arise if the MPLS network is capable of L-LSP or E-LSP without multiple COS capabilities. Each row is indexed by the pwVcIndex and indicate the PRI bits on the packet received from the user port (or VPLS virtual port) that are classified to this PW. Note that the EXP bit value of the PW is configured in the PW MPLS MIB module.
