Configuring cut-through Layer 2 forwarding
About this task
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.
Restrictions and guidelines
With cut-through forwarding, the device forwards CRC-error frames because it starts forwarding frames before their CRC field is received.
Procedure
1. Enter system view.
system-view
2. Enable cut-through forwarding.
cut-through enable
By default, cut-through forwarding is disabled.
