When a switch configuration includes a user-defined error threshold on a per-port basis, to which switching method will the switch revert when the error threshold is reached?
When the error threshold on a per-port basis is reached in a switch configuration that includes a user-defined error threshold, the switch will revert to store-and-forward switching method.
Store-and-forward switching is a method where the switch waits for the entire frame to be received before forwarding it to the destination. It checks the integrity of the frame by examining the frame’s header and CRC (Cyclic Redundancy Check) before forwarding it.
If the error threshold on a specific port is exceeded, it means that there is a high likelihood of data corruption or errors occurring on that port. In such a scenario, the switch will switch to store-and-forward mode in order to ensure that all frames are checked for errors before forwarding them, reducing the possibility of propagating corrupted data.
Store-and-forward mode has the advantage of providing error checking and reducing the chances of transmitting faulty frames. However, it introduces additional latency due to the need to wait for the entire frame to be received and checked before forwarding it.
