List of codes used on 802.3 and Ethernet networks. $Revision: 2.69 $ $Date: 1998/04/19 14:34:40 $ $Author: map $ $Id: Ethernet.txt,v 2.69 1998/04/19 14:34:40 map Exp $ This file contains collected information on the various codes used on IEEE 802.3 and Ethernet. There are three "pages" of data: type codes, vendor codes, and the uses of multicast (including broadcast) addresses. These same codes are also used on some other IEEE 802 networks (e.g. 802.5 is Token Ring), but may be in slightly different form. Specifically 802.5 sends the bits of a byte in the opposite order to Ethernet or 802.3, so the codes listed below may have the bits of each byte reversed (e.g. exchange 01/80, 10/08, 0C/30, etc.), although some monitors may undo the reversal back to the Ethernet order. Be careful using this reference for other IEEE 802 media. There is also this page of general info and a page of acknowledgments. I wish to thank the contributors, many are listed on the acknowledgments page and there are almost certainly others that I have missed. There is also a list of other sources of Ethernet info. Note that these pages are reports of codes seen "in the field" and are thus subject to errors of observation, and are certainly incomplete. They also report the actual vendor of the equipment rather than the original assignment of the code. The IEEE site (see below) has their info which is different. Whenever a question arises, I suggest consulting both lists for useful information. If you are reading this from a stored copy, you may want to get a more up-to-date copy on the net, or you may want to just bookmark the pointer for future reference. The three main URLs for the document are: (HTML in linked pages) (Text via FTP) (Text via Web) My thanks to Karl Auerbach at Cavebear for providing a place to make this available. If you are having problems with the servers, Karl is the one to contact, if you have questions or comments on the content, you can contact Mike Patton. Since this information is from collected wisdom, there are certainly omissions. I welcome any further additions which can be sent to Ethernet-codes@Cavebear.com. I appreciate it if submissions include a preformatted line for the acknowledgments section (mostly because I have trouble figuring out what abbreviations will be acceptable when names are too long), and to format lines as they are here in the main listings. These will ease my use of cut-and-paste to update the list with less effort. We are presently working out a mirroring strategy for these files. If you are interested in participating, please send mail to the address above, include any relevant info, we'll get back to you eventually... ---------------------------------------------------------------- The data on these pages was collected by Michael A. Patton, Internet Consultant, from contributions by the Internet community. Only a globally connected information community can produce collected wisdom like this list, and therefore, in addition to the specific contributors to the list, all those who make the Internet what it is are part of what made this list possible. ---------------------------------------------------------------- Other Ethernet info Other information about Ethernet and related technologies is available from various sites on the network. Charles Spurgeon at U. Texas has collected lots of information on Ethernet with lots of good configuration guidelines. Another site has collected references for Ethernet analyzers. Pointers to other general resources can be sent in for inclusion in future updates. Number assignment More information may be obtained from IEEE which assigns the vendor codes. You can get a full listing by sending E-Mail to info.stds.oui@ieee.org (any mail to that address will be responded to with the full list), you can also obtain the list from . The listing from IEEE contains company addresses as well as names, but is limited to those entries which the companies request be made public, while the list you are reading contains some entries determined from systems in the field. You can read more about this on the IEEE Standards Process Automation (SPA) System at with lookups at . ---------------------------------------------------------------- If you are interested in obtaining an assignemnt from the IEEE, the contact info I have is: IEEE Registration Authority IEEE Standards Department 445 Hoes Lane, P.O. Box 1331 Piscataway NJ 08844-1331 phone: (908)562-3813 Fax: (908)562-1571 Email: i.ringel@ieee.org ---------------------------------------------------------------- Type codes are still managed by Xerox as of 1 Jul 1997, but this is being transferred to IEEE.. The contact info I have for Xerox is: Xerox Systems Institute 3400 Hillview Ave. PO BOX 10034 Palo Alto, CA 94303 Phone: 415-813-7164 Contact: Fonda Lix Pallone The only info I have on the contact at IEEE for this is an E-Mail address: Anita Rickets (a.ricketts@ieee.org).

Only vendors are listed by Xerox, not what protocols. @ 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 codes 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. According to some informal correspondence, when the IEEE assigns an Ethernet address block, a block of 2**25 is reserved. Both a unicast and a multicast (group address) block, in a pair. Thus multicast groups for vendor-specific uses tend to match the non-multicast vendor assignments with "010000" added. This rule seems to be true for most of the addresses in these files. 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). 000001 SuperLAN-2U 000002 BBN (was internal usage only, no longer used) 000009 powerpipes? 00000C Cisco 00000E Fujitsu 00000F NeXT 000010 Hughes LAN Systems (formerly Sytek) 000011 Tektronix 000015 Datapoint Corporation 000018 Webster Computer Corporation Appletalk/Ethernet Gateway 00001A AMD (?) 00001B Novell (now Eagle Technology) 00001C JDR Microdevices generic, NE2000 drivers 00001D Cabletron 00001F Cryptall Communications Corp. 000020 DIAB (Data Intdustrier AB) 000021 SC&C (PAM Soft&Hardware also reported) 000022 Visual Technology 000023 ABB Automation AB, Dept.
