Ethernet frame types. There are several types of Ethernet frames. The different frame types have different formats and MTU values, but can coexist on the same physical medium. The Ethernet Version 2 [note 3] or Ethernet II frame or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol.

Language: English Location: United States Restricted Mode: Off Identifying the Data Inside an Ethernet Frame Each data-link header has a field in its header with a code that defines the type of protocol header that follows. For example, the Destination Service Access Point (DSAP) field has a value of E0, which means that the next header is a Novell IPX header. Mar 27, 2014 · Ethernet Version 2 and IEEE 802.3 Frame Formats ----- The Ethernet Version 2 frame format was designed before the IEEE specifications, but is almost identical to the 802.3 frame type. With the Ethernet Version 2 frame type, a two-byte Type field follows the source station's six-byte MAC address. Jan 22, 2019 · Length is a 2-Byte field, which indicates the length of entire Ethernet frame. This 16-bit field can hold the length value between 0 to 65534, but length can not be larger than 1500 because of some own limitations of Ethernet. For a more detailed discussion of this, which mentions a third possibility used by NetWare, and mentions the SNAP header that can follow the 802.2 header, see Ethernet Frame Types: Provan's Definitive Answer, by Don Provan. (XXX - we should mentioned that the 802.2/802.3 terminology used by Netware at that time is simply confusing)

An Ethernet frame starts with a header, which contains the source and destination MAC addresses, among other data. The middle part of the frame is the actual data. The frame ends with a field called Frame Check Sequence (FCS). The Ethernet frame structure is defined in the IEEE 802.3 standard. Here is a graphical representation of an Ethernet Whichever frame type the response comes back on is the frame format that the iSeries will use to communicate to that piece of equipment. For the Ethernet Version 2 frame, the EtherType field is set to '0806'. For an IEEE 802.3 Ethernet frame, the EtherType field in the SNAP header is set to '0806'. Length – Length is a 2-Byte field, which indicates the length of entire Ethernet frame. This 16-bit field can hold the length value between 0 to 65534, but length cannot be larger than 1500 because of some own limitations of Ethernet. An Ethernet frame works in a similar way. It is a container for data with a source and destination address to deliver information, called the payload, between two locations on the same network.
The original Ethernet IEEE 802.3 standard defined the minimum Ethernet frame size as 64 bytes and the maximum as 1518 bytes. The maximum was later increased to 1522 bytes to allow for VLAN tagging. The minimum size of an Ethernet frame that carries an ICMP packet is 74 bytes.
