RFC 3827 Additional Snoop Datalink Types June 2004
3. IANA Considerations
This document created a new IANA registry named "Snoop Datalink
Types" to hold the various possible 32-bit (4 octet) snoop datalink
types. This new registry holds the values previously defined in
[RFC 1761] and tabulated below:
Datalink Type Code
------------- ----
IEEE 802.3 0
IEEE 802.4 Token Bus 1
IEEE 802.5 Token Ring 2
IEEE 802.6 Metro Net 3
Ethernet 4
HDLC 5
Character Synchronous 6
IBM Channel-to-Channel 7
FDDI 8
Other 9
Additionally, the new registry also holds the values defined above in
section 2 of this document.
All new allocations and assignments to this registry starting from
code 27 will follow the First Come First Served policy outlined in
[BCP0026]. Type codes up to 26 not defined by this section of the
document (10-15 and 19-25) are considered reserved.
4. Security Considerations
The addition of new datalink type codes to the existing file format
poses no known security risks.
5. Acknowledgements

Strahm for meticulously reviewing this document.
