4383.0. "VNswitch 900EA down problem" by DEKITG::JUNGYOUNGNAM (Angelo Nam - hidden village!) Wed Apr 30 1997 01:45

    I have a customer with a baby GIGAswitch/ATM and two VNswitch 900EA.
    Refer following,

                   AlphaServer 1000A             AlphaServer 4100
                    (ATMworks 350)                 (ATMworks 350)
                          |                               |
                          |       4 155Mbps ATM ports     |
                +---------+-------------------------------+---------+
                |          Baby GIGAswitch/ATM (LANemulation)       |
                +--------------+----------------------+-------------+
                               |                      |
                               |                      |
                             DVNEA                  DVNEA
                           DEChub900              DEChub900
    
    From GIGAswitch to AlphaServer always works fine, it means no problem
    within the GIGAswitch box. But the problem is in the VNswitch 900EA.
    When we reset (power cycle) the DVNEAs, they runs ok. Pinging from any 
    direction works ok. But two or three hours later DVNEAs goes to hang.
    Sometimes the all the green LED which are used to monitor 10BaseT traffic
    turn on with hang. Current firmware version is V1.5. DEChub900 firmware
    is V5.0.
    
    Any one got any ideas on what is the problem? 
    Firmware? This is the third firmware ever I have applied. 
    Any comment greatly appreciated.
    
    Thanks,
    Angelo
