Switch latency is measured from port-to-port on an Ethernet switch. If I also connect them with ethernet cables using 1 or 2 or 3 ports and then add them to the lag of the two fiber abobe, they still work but do you think that this improves the bandwith between the switches? thanks 10-09-2023 07:40 AM. Network latency is any kind of delay it takes for data or a request to go from the source to the destination over a network. Network.
