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
