5.7.4 bridge forward-mode

Function
The device supports two types of frame forwarding, store-and-forward and cut-through.
Store-and-forward
After a full frame is received, an error check is performed before forwarding.
Cut-through
After reading the first 64 bytes of a received frame, forwarding is immediately performed.
Basically, FSC errors are not checked, allowing low latency forwarding.
Use the no form to return to store-and-forward.
Prompt
xg(config)#
Command syntax
bridge forward-mode { cut-through | store-and-forward }
no bridge forward-mode
Parameter
forward-mode { cut-through | store-and-forward }
Specifies the switching method.
