Not if you want to interoperate!

If you look at http://www.iana.org/assignments/port-numbers you will see that IANA has
allocated port 701.

lmp             701/tcp    Link Management Protocol (LMP)
lmp             701/udp    Link Management Protocol (LMP)
#                          RFC-ietf-ccamp-lmp-10.txt

First, note that link property correlation is a core (mandatory) function, but link
connectivity verification is an optional procedure.
Second, the link connectivity verification procedure can be run at any time to verify the
physical connectivity.

However, if you do run the link connectivity verification procedure at start of day in
order to determine and exchange the Interface IDs, you would be wise to run the procedure
before link property correlation because that way you will know which links are being
bundled or described in the link property correlation phase.

Perhaps someone with some running code would care to comment?
