The frame padding fixed enable command enables a board to reserve the padding fields in upstream Ethernet packets.
The undo frame padding fixed enable command enables a board to delete the padding fields in upstream Ethernet packets.
By default, a board deletes the padding fields in upstream Ethernet packets.
Usage Scenario
If Huawei devices are connected to non-Huawei devices, non-Huawei devices cannot identify these packets without the padding fields. To enable non-Huawei devices to identify these packets, configure the frame padding fixed enable command on Huawei devices to enable the Ethernet interfaces to reserve the padding fields in upstream packets.
