Usage Guidelines

The control-word option carries control-word information in each encapsulated packet. The information is used for packet sequence verification, packet fragmentation, and packet reassembling on the forwarding plane.

By default, the control-word is used in packet encapsulation. If a non-huawei device does not support control-word information in the packet structure, the label-type { { label-alert | normal } no-control-word } command can be used on the Huawei device to remove the control-word option from each packet sent to the non-huawei device to facilitate their interworking.

If a non-huawei device supports control-word information in the packet structure, the undo no-control-word command can be used on the Huawei device to restore the Huawei packet structure.

Only PWE3 Ping and PWE3 Trace test instances support the undo no-control-word command.
