What is an Ethernet Frame?

The packets on the Ethernet link are called Ethernet frames . The beginning of an Ethernet frame consists of a preamble and a frame start character. Followed by an Ethernet header, the destination address and source address are described by the MAC address. The middle of the frame is a data packet (such as the IP protocol) containing other protocol headers of the frame payload. An Ethernet frame is terminated by a 32-bit redundancy check code. It is used to check whether data transmission has been damaged.

Binary packets from the line are called a frame. The frame seen from the physical line can see, among other things, the preamble and the start of the frame. Any physical hardware will need this information.

The table below shows

There are many types of Ethernet frames. Different types of frames have different formats and MTU values. But they can exist on the same physical media.

• Ethernet version 2 or Ethernet II frames, or DIX frames, are the most common frame types. It is usually used directly by the IP protocol.

• A short frame is an Ethernet frame whose size is less than the minimum length of 64 bytes defined by IEEE 802.3. Possible causes are conflicts in Ethernet communications, insufficient data, network card errors, or software errors. ^[1]
