Store-and-Forward Switching

Store-and-forward has two primary stages:

Error Checking –

• The switch will check the Frame Check Sequence (FCS) for CRC errors
• Bad frames will be discarded
• Frame size is up to 9,200 bytes

Buffering –

• The ingress interface will buffer the frame while it checks the FCS
• This also allows the switch to adjust to a potential difference in speeds between the ingress and egress ports
