Usage guidelines

A cut-through forwarding-enabled device forwards a frame after it receives the first 64 bytes of the frame. This feature reduces the transmission time of a frame within the device and enhances forwarding performance.

A frame is forwarded before its CRC field is received, and thus CRC-error frames are forwarded instead of being dropped.

Examples

# Enable cut-through forwarding on the device.

<Sysname> system-view

[Sysname] cut-through enable
