For rate calculations, these feature only include the frame length between the destination MAC address (DMAC) and the CRC field. You can optionally include the following overhead fields in rate calculations by enabling rate adjustment: • Preamble-7 bytes • Start frame delimiter-1 byte • Destination MAC address-6 bytes • Source MAC address-6 bytes • Ethernet type/length-2 bytes Quality of service 977
