WebMar 1, 2024 · 1-byte DSAP field in the 802.2 LLC header was too small. As a result, the IEEE introduced a new frame format with a Sub-Network Access Protocol (SNAP) header after the 802.2 header, as shown in the third style of header in Figure 1-4. Finally, in 1997, the IEEE added the original DIX V2 framing to the 802.3 standard as well as shown in … WebGitiles.
