Note that PRI bits transparency is lost in this case. - 'addVlan' indicate that a VLAN field will be added on the PSN bound direction. pwVcEnetPwVlan indicate the value that will be added. - 'removeVlan', 'addVlan' and 'changeVlan' implementation is not required.

It MUST be equal to pwVcEnetPwVlan if 'noChange' mode is used. The value 4096 indicate that no VLAN (i.e. untagged frames) on the port are associated to this PW.
