Well, we keep a copy in all the manuals, but I'll post it anyways,
since some of those are getting dated. Quite a few proprietary
(customer) protocols are supressed in this list, sorry. At least
we'll post most of it, unlike Xerox/ANSI on Ethernet.

Proteon ProNET-10/80 data link types:
1 IP
2 IP with trailing headers
3 Address Resoloution Protocol
4 Proteon HDLC
5 VAX Debugging Protocol (MIT)
10 Novell NetWare
11 Vianetix
12 PUP
13 Watstar protocol (University of Waterloo)
14 XNS
15 Diganostics
16 Echo protocol (link level)
17 Banyon Vines
20 DECnet (DEUNA Emulation)
21 Chaosnet
23 IEEE 802.2 or ISO 8802/2 Data Link
24 Reverse Address Resolution Protocol
29 TokenVIEW-10

Just because a protocol is on this list does not mean that there is
any implementation of it on ProNET.

Of these, protocols 1, 14, and 20 are the only ones that have ever
been seen in ARP packets to my knowledge.

For reference, the header is (one byte/line):

        destination hardware address
        source hardware address
        data link header version (2)
        data link header protocol number
        data link header reserved (0)
        data link header reserved (0)

Some protocols have been known to tuck stuff in the reserved fields.

Those who need a protocol number on ProNET-10/80 should contact me
(jas@proteon.com).
