WebNov 17, 2024 · Store-and-forward switches store the entire frame in internal memory and check the frame for errors before forwarding the frame to its destination. Store-and-forward switch operation ensures a high level of error-free network traffic, because bad data frames are discarded rather than forwarded across the network, as illustrated in Figure 6-9. WebThe FIB is a memory construct used by Ethernet switch to map a station's MAC address to the switch port the station is connected to. This allows switches to facilitate communications between connected stations at high speed.
