Questions tagged [switching-modes]
For questions about switching modes on network devices, where the switching mode determines whether the switch begins forwarding the frame as soon as the switch has read the destination details in the packet header or waits until the entire frame has been received and checked for cyclic redundancy check (CRC) errors before forwarding them to the network. For instance, you want to change the switching mode from the standard Cut-Through to Store-and-Forward.
