There are basically four types of modes in which switch can operate:
2) Cut thorugh : Only 14 bytes receive, check destination forward the packet. Faster than Store and Forward.
3) Fragment-free : Checks for first 64 byte, if proper forwards the data.
4) Adaptive : Changes to any of the above modes based on CRC error count and runt count (possible collision)
Eg : Store and forward switched : Dlink DES-1008PA 8-PORT, HP E6600 Cut through : NETGEAR XSM7224S, Cisco Nexus 5010 Fragment free : Cisco catalyst 2100 ( supports all )
