I am confused about which Ethernet frame type everyone uses with TCP/IP
today. I understand that there are four different types. I see from the
Cisco website that they talk about only two of these four. The two they
discuss are called Ethernet and IEEE 802.3. The one Cisco calls Ethernet has
the following fields
Preamble
Destination Address
Source Address
Type
Data
CRC
The one Cisco calls IEEE 802.3 has
Preamble
Start Frame Delimiter
Destination Address
Source Address
Length
Data and 802.2 Header inside the data area as best I can tell
CRC
Why do they mention these two only? Who uses what?
