List of codes used on 802.3 and EtherNet networks

List of codes used on 802.3 and EtherNet networks.


Last update: 8-Apr-93



This file contains collected information on the various codes used on
IEEE 802.3 and EtherNet.  There are three "pages", type codes, vendor
codes, and the uses of multicast (including broadcast) addresses.  I
wish to thank the contributors, some are listed below and there are
almost certainly others that I have missed.  A complete up-to-date
copy of this file may always be obtained with anonymous FTP from
FTP.LCS.MIT.Edu with the name pub/map/EtherNet-codes.  Since this
information is from collected wisdom, there are certainly omissions.
I welcome any further additions which can be sent to me at

�"Type" Fields


The 13th and 14th octets of an Ethernet or IEEE802.3 packet (after
the preamble) consist of the "Ethernet Type" or "IEEE802.3 Length"
field. The "Ethernet Type" values are managed by XEROX.  Some
assignments are public (see + below), others private.  Current
information includes:  Xerox Public Ethernet Packet Type
documentation(Xerox Courier Vol. 3 Issue 4 October 1988); IEEE802.3
Std; NIC RFC1010; contributions from network managers and vendors.

% BBN Private Protocols, not registered
+ These protocols are mentioned by Xerox in their October 1988 issue of
  COURIER (page 8-9) as the publicly assigned numbers.  Only vendors are
  listed by Xerox, not what protocols.  For more information about type field
  assignments, contact: Pam DuPuy, Xerox Systems Instuture, (408)737-4652.
@ According to the October 1988 issue of COURIER (page 8), "if it is less
  than 600H, the packet is assumed to be an 802.3 packet; if it is greater
  than 600H, the packet is flagged as an Ethernet packet."
�Vendor Addresses

Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits
(0-9, plus A-F, capitalized). These 12 hex digits consist of
the first/left 6 digits (which should match the vendor of the Ethernet interface
within the station) and the last/right 6 digits which specify the interface
serial number for that interface vendor.

Ethernet addresses might be written unhyphenated (e.g. 123456789ABC),
or with one hyphen (e.g. 123456-789ABC), but should be written hyphenated
by octets (e.g. 12-34-56-78-9A-BC).

These addresses are physical station addresses, not multicast nor
broadcast, so the second hex digit (reading from the left)
will be even, not odd.

At present, it is not clear how the IEEE assigns Ethernet block addresses.
Whether in blocks of 2**24 or 2**25, and whether multicasts are assigned
with that block or separately. A portion of the vendor block address
is reportedly assigned serially, with the other portion intentionally
assigned randomly. If there is a global algorithm for which addresses
are designated to be physical (in a chipset) versus logical
(assigned in software), or globally-assigned versus locally-assigned addresses,
some of the known addresses do not follow the scheme (e.g AA0003; 02xxxx).
