Current Ethernet and IEEE802.3 "Type" Fields 5/5/88

|
|
The 13th and 14th octets of an Ethernet or IEEE802.3 packet (after the preamble)
|
|||
|
|
consist of the "Type" or "Length" field. These are formerly assigned by
|
|||
|
|
Xerox, currently assigned by IEEE. Some assignments are public, others private.
|
|||
|
|
Information currently available includes: Xerox Public Ethernet Packet

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.
|
|||
|
|
|
|||
|
|
Currently we have noted the following vendor addresses, on the
|
|||
|
|
BBN Corporate Ethernet.

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), I am unaware of the algorithm.
