1637.0. "FDDI Utiliztion info via DECBridge 900MX" by NCMAIL::SCHEID () Mon Oct 31 1994 12:16

    My customer has several DECbridge 900mx's and is essentially running 
    dedicated personal ethernet out the front ports. He currently has
    about 14 workstations attached to DECbridge 900MX on a ring. When 
    using HUBwatch for VAX v3.0, through the DECbridge 900mx summary page
    and the FDDI summary info. ... it says he is running @ 27-34%. Customer 
    was very concerned at that utilization for only 14 workstations. So 
    he put a analyzer on net and saw only 2-5% utilization. 
    
    
    Is this FDDI info different than what the customer is looking for ...
    which is ring utiliztion...

    My guess is that you have Ring Purger enabled on at least one DEC FDDI
    station - this could be a concentrator or bridge or end station.  With
    Ring Purger enabled, void frames get figured into the utilization
    calculation.  Find out which station it is, and disable it.  Also,
    you could use the analyzer to confirm that there is indeed a
    large amount of void activity on the ring.
