4669.0. "DEMFA (FDDI) Support ?" by MFRNW1::SCHUSTER (Karl Schuster @MFR Network Services) Thu Mar 11 1993 08:50

    A customer has connected his 8 VAX6000 to FDDI via DEMFAs.
    
    For the LINE MFA-0 I can get COUNTERS and CHARACTERISTICS, but no
    STATISTICS. The following error is returned:
    
    ... cannot locate services required information for computing statistics
    
    ( I have set the line speed to 100000000 )
    
    Does that mean, that the DEMFA is not yet supported fully with MCC V1.2
    ?
    
    Will it be supported with V1.3 ?
    ( This absolutely important !!! )

4669.1another DEMFA user...GIDDAY::DRANSFIELDMike Dransfield, Sydney RSSGTue Apr 06 1993 06:0911
    I also have problems with a DEMFA at a customer site.
    This is with MCC 1.2.3
    I get a couple of errors.
    on SHOW CHAR  get no corresponding entity instance exists
    and som messages extra info returned code 63, 62 and similar
    message with SHOW COUNT but different codes.
    IMPM and FCL behave differently.
    
    What is the story?
    thanks,
    Mike

    Put a short log (example) of the request showing the problem,
    preferably against a node on the enet so that I can get to it
    as a reply here.

Hi,


This is a customers system, but it seems like the problem exists in 1.3 as weel.

4669.4When is the demfa going to be supported?GIDDAY::DRANSFIELDMike Dransfield, Sydney RSSGTue May 18 1993 02:2511
    
    What is the story with the DEMFA?
    Is it supposed to be supported or what?
    I was just out at the customer site again today and they are now using
    V1.3 MCC and when you try to show characteristics on the mfa-0 circuit
    it returns a few error messages about extra information returned and
    a couple of other errors I didn't keep.
    
    I need support for the demfa please!
    thanks,
    Mike
4669.5looking into itTOOK::PURRETTATue May 18 1993 18:429
    You're right.  It looks like FDDI protocol is not fully supported
    by the AM.  I'll spend some time figuring out what it would take
    to get it supported and bring it to management.  There may be something
    we can do cheaply in the meantime to get things working better than
    they do now which could be field installed rather than waiting for
    a new release.  Please also be aware that we don't have many resources
    back here (I work mainly on phaseV and common agent but jump in to
    help with phaseIV issues when they arise).  We're trying to do the best
    we can.
4669.6What next?GIDDAY::DRANSFIELDMike Dransfield, Sydney RSSGWed May 19 1993 06:2713
    re: .5
    thanks for the reply.
    So what do I have to do to get it supported?
    We are talking about one of our major customers here!
    They are spending about US$4M in the next twelve months if we look
    good....
    Do you want me to raise a CLD for this problem... I already have two
    open, so another one isn't a problem for me :-)
    
    I know its tough, but it's also tough trying to explain to customers
    why things don't work the way they want them to.....
    cheers,
    Mike
4669.7TOOK::MINTZErik Pavlik MintzWed May 19 1993 11:146
Engineering is examining what workarrounds may be possible in the short term.
However, to get "full support" I suggest that you contact product management.
They are the people who prioritize the requirements for implementation
changes.  In this case, try Laura (MOLAR::) Sargent.

    >Engineering is examining what workarrounds may be possible in the
    >short term
    
    	Is a work around available yet ?
    	Another customer has reported the same problem with decnet phase4
    	AM over FDDI. Show line and circ counters from the iconic map
    	produced many many pop up boxes with warning messages about extra
    	information being returned. 
    
    	I will send mail to Laura (MOLAR::) Sargent as suggested in .-1
    	but would be nice to have a temporary workaround. 
    
    Regards,
    Andrew
4669.9WorkaroundTOOK::PURRETTAWed Jul 14 1993 13:1410
    I've provided Mike Dransfield two new .COM procedures to
    replace the dictionary definitions of DNA4 Circuit and Line
    with something which won't give you all those pop-up windows.
    MCC will display those attributes returned which overlap with
    ethernet attributes.  Attributes which are specific to FDDI (new)
    will require development support in the AM and Dictionary.
    
    It looks like Mike is in the same area as you are so you might
    try getting the new procedures and instructions from him.
    Otherwise send me mail - TOOK::PURRETTA
