This is used to enable creating, deleting, and modifying this row. It is the standard RowStatus control for provisioning or tearing down an individual Ethernet-over-pseudowire VC entry, and until it is set to active none of the VLAN-handling or port-association values configured in the same row actually take effect on live traffic. For example, a provisioning workflow sets cpwVcEnetVlanMode, cpwVcEnetPortVlan, and cpwVcEnetPortIfIndex together in one SNMP SET along with setting this to createAndGo, atomically bringing up a fully configured Ethernet pseudowire in a single transaction.
