Ethernet frame type

Ethertype: Ethernet Type field and Value
Ethertype is a field in an ethereframe. It is used to specify the Protocol applied to the frame data field. According to 802.3, the length/ethertype field is a field of two eight character segments. The meaning of the two is one, depending on the value. In quantitative evaluation, the first eight-byte field is the most important. When the field value is greater than or equal to the decimal value 1536 (that is, the hexadecimal value is 0600), The ethertype field represents the type of the Mac client protocol (ethertype interpretation. The length of this field is mutually exclusive with the ethertype.
This field value is taken from the IEEE ethertype field register. The ethertype field is a limit space, so its allocation is limited. Only those who develop new data transmission protocols need to use the ethertype field, regardless of whether they actually produce any device. The authority for the authorization of the ieee rac ethertype field is responsible for checking and approving the ethertype field.
The ethertype value has been assigned to the well-known protocol. The following table lists the common values in the ethertype field and their corresponding protocols:
