Cut-Through Switching, aka fast-forward switching, is a kind of #switching mode that immediately forwards the frame received after the check on destination 202206151451#. Latency is not a problem, but in this mode, frames errors will be easily transmitted to other network segments.

Switch
It has three primary frame switching modes: Cut-Through Switching#, Store-And-Forward Switching# and Fragment-Free Switching#. All of them will check the destination and source Media Access Control Address (MAC), then check against the table, which contains entries that map Switch port to a particular MAC, maintained by Switch. It will place an entry for the source MAC corresponds to the switch port where the frame came (if it hasn’t done so before), and check whether there is an entry for the destination MAC. If there is not, it will flood (send frames to all other ports) the frames, and waits for the response. If there is such a response coming from one of the switch’s port, it will map that port to the destination MAC and immediately forward the packet to the port. Otherwise, depending on whether the destination MAC is in the same network segment, it either doesn’t forward the packet or forward the packet to the port specified in the table (filtering).

Fragment-Free Switching
Fragment-Free Switching is a kind of #202207051907 which forwards the frame after reading the first 64 bytes of it. It is basically a modified 202207061210.
