cisco's documentation is just plain wrong in some files (some fields are
reversed, some field sizes are twice as long as they really are).

two documents that as far as i can tell don't contain flaws are:

http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/nfc/nfc_3_6/iug/format.pdf
http://www.caida.org/tools/measurement/cflowd/configuration/configuration-9.html

i've filed bug reports with both cisco and juniper for flaws in
documentation & implementation that i found writing the dissector. as a
general rule, cisco doesn't retroactively fix documentation - so always
use the latest version of the nfc software's documentation.
