WebNov 9, 2024 · The data in an ethernet frame is the payload of an ethernet frame. Your Question 1 assumes that every layer-3 protocol is IPv4, and every layer-4 protocol is TCP, which are bad assumptions. Ethernet doesn't know or care which layer-3 protocol it carries (IPv4, IPX, IPv6, AppleTalk, etc.), so the data of the frame is the payload. WebAs you can see from below image (not including the preamble and SFD), the minimum size of an Ethernet Frame must be 64 bytes (6+6+2+46+4) and maximum size of an Ethernet Frame 1,518 bytes (6+6+2+1500+4). …
