5.6.4 bridge forward-mode
Function
For the switching method of frame forwarding, the XG700 supports two types of 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 data up to the beginning 64 bytes of a received frame, forwarding is immediately performed. Basically,
FSC errors are not checked, which allows low latency forwarding.
Use the no form return to the default setup.
