328.0. "FDDI SMT version?" by CSC32::D_KOFOL (Dave Kofol CSC/CS Network Support) Thu Aug 22 1991 02:14

	I've spoken to a customer that has a DECbridge 500 in a network
with 2 FDDI Cisco routers, 2 Sun file servers, and 2 DECstation 5000s.
The customer claims he's experiencing problems with loosing IP packets,
and with DECnet/Ultrix routing.  The customer claims that his symptoms
don't exist with the DECbridge 500s out of the network.  The customer
has spoken to Sun about his IP problems, and Sun states that we need
to find out what version of SMT is being run on the DECbridge 500s so 
it can be compared to the SMT version of the Sun FDDI controllers.
The customer dosen't have ELMS, so I don't know what version of 
microcode the DECbridge 500s are running, but I looked at the SMT
version of a couple of DECbridge 500s that we are using.  The SMT
version is a "1", and the version of microcode is V3.0.1.  What does
a "1" for the SMT version represent?  The SMT version should be
something like 5.1

328.1It is SMT frame's version ID, not Document Rev.EWBV06::IDOThu Aug 22 1991 05:3612
    V5.1 or V6.2 are the revision number for ANSI draft SMT document. So,
    I think this document number dosn't exsist in any SMT frames. 
    
    A value "1" you are seeing specifies the SMT Frame's version which
    identifies the structure of SMT frame header and information field. 
    I recall this number was "00 00" in SMT Document Rev 5.1., but now
    it is "00 01" in V6.2.  For more detail information, please see
    at part of SMT header in ANSI SMT document.

    Sun is confused.  SMT version mismatches might possibly cause some
    problems, but frame loss of user data frames is NOT one of them!
    
    Please get more details on the symptoms, and let it be known that the
    folks at Sun are way off base.
