Hello , Could anyone give me the translation of these ethernet protocols or give a pointer to a site I could FTP an extensive list of protocols along with their translation ,as I might discover new protocols on our network and I wouldn't like to send such a request every week or so ... Thank you all, Joseph. Please email if you have partial answer to my request and I will summarize them unless someone can provide me with a FTP site ( no need to have the job done twice , right ??? ) E-mail : politis@vmsa.technion.ac.il Politis Joseph Network Team at the Technion Institute Haifa ,Israel. /*********************** start of unknown protocols **************************/ x0808 : x0dc0 : x2020 : x2573 : x2e80 : x2e87 : x302c : x3731 : x3ae5 : x3c01 : x3c02 : x3c03 : x3c07 : x3c09 : x3c0a : x3c0b : x3c0d : x4430 : x4500 : x454d : x4920 : x5612 : x6520 : x656c : x6814 : x6c0c : x6d65 : x6e80 : x6f63 : x726f : x7365 : x736d : x7415 : x7420 : x7503 : x75e6 : x7ae5 : x7ee5 : x8787 : x8b50 : x8c1a : x9ad9 : xaaaa : xbf41 : xe0d1 : xe83c : xffff : /********** end of unknown protocols ( until the next one appears !!!)*******/

The list is maintained in the "Assigned Numbers" RFC (RFC 1060, unless it has been republished recently), available from the standard places. But I think that most of the numbers you are seeing are bogus values. Values like 2020, aaaa, and ffff are not legit - aaaa is commonly seen in test packets, often with a source Ethernet address of aa-aa-aa-aa-aa-aa. But I suspect that most of the rest are simply from corrupted packets that happen to have a valid checksum - odds are that 1 in 65,536 corrupted packets will have a good checksum, or maybe more (this would require a detailed electrical analysis to know for sure). If you can count packets of a given type, make sure you're seeing them with a higher frequency than your checksum error rates would account for. Doug Nelson Michigan State University

Just a small correction. The probability of an error getting through the
