[comp.dcom.lans] Token Ring NAUN?

jim@cdp.UUCP (08/31/89)

Does anyone know how to request the address of a Token Ring adapter's
NAUN (Nearest Active Upstream Neighbor)?  Ideally, the request would
be a Netbios request (like a remote status request).  I would like to
write a simple program to check the status of all the adapters on the
network periodically, without having to keep updating a list of
adapter addresses.  I've read (parts of) Schwaderer's Netbios book
and Haugdahl's Token Ring and Netbios books and I still don't know
how to do it.  The NAUN is (optionally?) part of the subvector ID in
a MAC frame (it says) but how do you elicit it and how do you receive
it?

Thanks for any help or pointers,
