[comp.dcom.lans] Type Filed Codes

hamish@waikato.ac.nz (12/18/90)

Here is the address as given in RFC1060 for obtaining an Ethernet type code

Xerox Corporation,
Xerox Systems Institute,
475 Oakmead Parkway,
Sunnyvale
California, CA94086
Attn: Ms. Fonda Pallone (408)737-4652

This might induce those who thing not having a valid type field is OK, to clean
up their act. You wouldn't believe the trouble you could get into without
having one.

BTW An IEE 802.3 length field can be told apart from a type field, because its
value will always be in the range 0x0000 - 0x05dc. This is given in RFC1060
"Assigned Numbers"
 
The next lowest type field is 0x0101 - 0x01ff which is Experimental.

(RFC's can be downloaded from nic.ddn.mil in rfc:)

Hope this helps.
