If I'm not mistaken, 9000bytes is the max.
I don't understand how ethernets, at the MAC layer, can support frames greater than 1500 bytes. Looking at the MAC frame format, we have: ethernet DIX V2 DA(16 bits), SA(16 bits), type (16 bits), data IEEE 802.3 DA(16 bits), SA(16 bits), length (16 bits), LPDU (802.2) The traditional way to distinguish between the 2 formats depends on the length value (in 802.3) being no greater than 1500, and on the type value (in DIX) being greater than 0x05dc (1500 decimal). Assuming you're still going to allow both formats on the same lan, how does it work if the length is greater than 1500? Tony Rall
