WebThis 2-byte field identifies the upper layer protocol encapsulated in the Ethernet frame. Common values are, in hexadecimal, 0x800 for IPv4, 0x86DD for IPv6 and 0x806 for ARP. Data Field This field (46 - 1500 bytes) contains the encapsulated data from a higher layer, which is a generic Layer 3 PDU, or more commonly, an IPv4 packet. WebIEEE 802.3 defines the polynomial M (x) as the destination address, source address,length/type, and data of a frame, with the first 32-bits complemented. The result of CRC is complemented, and the result is the IEEE 802.3 32-bit CRC,referred to as the Frame Check Sequence (FCS) field. The FCS is appended to the end of the Ethernet …
