Configuring cut-through forwarding

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 and enhances forwarding performance.

To configure cut-through forwarding:

 

Step

Command

Remarks

1.     Enter system view.

system-view

N/A

2.     Enable cut-through forwarding.

cut-through enable

By default, cut-through forwarding is disabled.

 

 

NOTE:

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