Hi Jack ,
     Try
http://www-lor.int-evry.fr/~pascal/NetInfos/cisco-lsap.html
This was originally from Cisco's web site by the looks of it.
As far as your other question goes, the document above calls the single
byte values LSAP's. I think it's a more generic term than DSAP and SSAP
(which are destination and source subnetwork access points). However I have
another document stuck to the wall here which is about Novell frame types.
It calls the whole two byte value (eg. AAAA in the case of ethernet SNAP)
an LSAP, so there does seem to be some confusion.
Hope this helps
Regards,
     Lachlan

I have recently been studying DLSW, but I am having a difficult time
understanding the concepy of an LSAP and LSAP filtering and I can't seem to

find a succint explanation. If I am understanding this correctly, LSAP is
simply the term for the two byte value in a frame header that is a
combination of the DSAP and SSAP. If this is incorrect, could someone
please set me straight. Also, does anyony have a good reference that lists

common LSAP values? I cna't seem to find one on the CD or Cisco's web
site.
  Any help would be greatly appreciated.
