851.0. "GIGAswicth-Omni9 problem" by DAIVC::IVAN () Wed Mar 05 1997 02:58

    Dear all,
    
    Our customer has GIGAswitch/ATM and Xylan OmniSwitch-9.
    They bought OmniSwitch from Xylan reseller here. Now
    they have problems in connecting the OmniSwitch to GIGAswitch.
    
    Xylan's reseller engineer describe the problem as:
    "LANE connection has experienced failure when the LEC on
    Omni-9 can not reestablish link to LES/BUS services in the
    GIGAswitch".
    The engineer has requested us to do one of the following steps
    to solve the problem:
    - set the Do_Keep_Alive flag to zero (0)
    - upgrade the firmware to 2.11a
    
    My questions:
    
    - Do we have the same problem with DECswitch 400?
    - Could someone please explain what is the Do_Keep_Alive flag?
      (I can not find it in manuals)
      ... and how can set its value?
    - I know firmware version 2.11, but never hear 2.11a.
      Is it the same as 2.11?
    
    
    best regards

    Ivan,
    
    Can you give me some more information about this customer? Perhaps
    you could send me email. 2.1.1a was built as a debug version to help
    isolate a problem at one customer site. It has no bug fixes. The steps
    listed above are part of the instructions given to help isolate this 
    problem, but did not seem to affect it. We are still working with the
    original site to isolate this problem. It looks like you have another
    customer seeing similar symptoms, and we would like to get more data.
    Could you contact me so we can discuss?

    The keep-alive flag is a debugging tool, not a customer feature.  So
    I'd expect the manual to say nothing about it.

    To set it, you type

            do_keepa = 1           to  enable UNI/ILMI keepalive polling
                                   and the possibility that if the other
                                   node doesn't respond, the GS/ATM will
                                   be forced to declare the ILMI dead

    or      do_keepa = 0           to disable UNI/ILMI keepalive polling
                                   and pretend that ILMI is just fine

    Note that the setting is NOT preserved in flash and that the new CLI
    will prevent customers from accessing it.
