840.0. "LAT over ATM" by MUNICH::WOERLE () Mon Feb 24 1997 04:36

		hello,

a customer wants to setup LAT over ATM on a Digital-UNIX.
But he doesn't fail.
When he does a  #latcp -e elan0 he gets the error 
"Invalid network adapter elan0 specified"

The configuration:
Digital Unix V4.0B
Alphaserver 2100 Modell 4/233 (firmware V3.8)
ATM-Adapter : ATMWORKS 350
ATM-Switch : FORE

The customer has LANEmulation und IP is working properly with ATM.
Only LAT makes trouble.

Can someone give me some hints about setting up LAT over ATM ?
And is this supported ?
(Sorry, but I'm a novice in ATM)


In the following are further details of the customers configuration.

Many thanks in advance

Norbert Woerle, CSC Munich

    Hi
    
    I don't think that LAT (and DECnet, ...) over LANE is supported
    (see below). However, on OpenVMS it works.
    
    Gruss Walter.

Subj:	Digital Unix 4.O? and MULTICAST/ MULTIPROTOCOL SUPPORT

Hi 


      Digital Unix Engineering is attempting to deliver Multicast support
  for support of Decnet,Lat,IPX etc.. using Lane on Digital Unix. However
  they need to identify real customers that have been requesting this 
  need.

  Ranjeet we are asking that you send this out to all SE'S, WIZARDS etc..
  
  If they have a customer with this requirement please ask them to send
  me mail with the customer name address and contact. And a brief writeup
  of there requirements:

  They can send the reply to [email protected]
                          or mts$::"lkg::jim snay"
                          or NPSS::SNAY

  ThankYou
  Jim Snay
    
840.2Not officially supportedSMURF::GREBUSDTN 381-1426 - Digital UnixWed Feb 26 1997 11:448
    Digital UNIX has never claimed support for LAT over LANE.  It has never
    been formally qualified by the group responsible for the LAT code.  In
    some informal testing here, it appeared to work and got further than
    this latcp command error.  I'm not sure what might be different in this
    case.

840.4not really an ATM problem pre seSMURF::MENNERit&#039;s just a box of Pax..Thu Feb 27 1997 20:093
    Found this problem to be caused by a new version of the DLB (Data Link
    Bridge) which was merged into V4.0B very late in the game.  Hope to
    have a patch availible soon.

    So just to clarify, LAT is still officially/unofficially

    LAT still is unsupported over ATM but since this is not a LAT (or 
    even an ATM) problem per se, the DLB will be fixed.  Ofcourse the fix
    will go into  a development pool.  To get a patch will require an
    IPMT.  The IPMT should state something to the effect that the V4.0B
    DLB does not support dynamic interfaces.  
    
    i have tried to get the owner engineering groups to verify their
    products over LANE but have had NO success.

    		hello,
    many thanks for all your replies.
    
    The customer now wants a patch.
    If I have understood the last reply correctly I must open an IPMT
    
    .-1"Ofcourse the fix will go into  a development pool.  To get a
    patch will require an IPMT."
    
    Okay but to whom should I send the IPMT ? To ATM Engineering or to
    Digital UNIX ?
    
    
    The customer wants to do LAT over LANE.
    If I have the last replies understood correctly the LAT over LANE is
    *NOT* supported. 
    When the customer wants this functionality should he send mail like
    described in .1 :
    "			      [email protected]
                              or mts$::"lkg::jim snay"
                              or NPSS::SNAY  "
    
    Many thanks in advance
    
    Norbert

    IPMT cases for problems with Digital UNIX software should go through
    the Digital UNIX support process.
    
    LAT over LANE is not officially supported.  Since this is a request for
    a new supported feature, it should go to Digital UNIX product
    management.  I believe Steve LeBlanc is the product manager responsible
    for the network area.

    But if you enter an IPMT which states that the Data Link Bridge (the
    DLB), does not support dynamicly added interfaces - then a patch
    could be generated which will allow LAT to work (offical support
    is another issue...)
