Most Ethernet interfaces also either don't supply the FCS to Wireshark or other applications, or aren't configured by their driver to do so; therefore, Wireshark will typically only be given the green fields, although on some platforms, with some interfaces, the …
Webb17 nov. 2024 · The Preamble field is not included when describing the size of a frame. Any frame less than 64 bytes in length is considered a collision fragment or runt frame and is automatically discarded by receiving stations.
