When switching data frames, a switch can select different modes to meet network and user needs. Cisco switches provide three switching modes:
Storage forwarding Mode
The Store-and-forward mode means that the switch can complete the entire data frame and perform the forwarding operation only after the CRC verification is passed. If CRC verification fails, that
