That depends on the switch. Even on the same switch, might vary depending on whether it might change how it forwards frames, e.g. cut-through vs. store-and-forward. Also depends on port speeds and, for store-and-forward, frame size. Rough ball park might be 10 to 40 microseconds.



"Cut-through switches can reduce switch-to-switch latency from 15 to 50 microseconds to 2 to 4, he says. "
