4289.0. "PA with decbridge 620 utilization wrong?" by GIDDAY::DRANSFIELD (Mike Dransfield, Sydney RSSG) Mon Dec 21 1992 00:59

    I have a couple of problems with fddi stuff and MCC.
    
    This is on MCC VMS v1.2.1
    
    1) The performance analyzer seems to be calculating the utilization
    wrong for a decbridge 620 ethernet port. Running a test which involves
    going from an ethernet across a decbridge onto an fddi ring then
    via a concentrator to a second decbridge 620 and finally to a target
    ethernet segment.  The test involves loading the ethernet to about 60%
    utilization and then looking at the utilization on each ethernet from
    the decebridge 620.
    The counters look reasonable, but the utilization on the first ethernet
    is returned as 61% (looks ok) whereas the second bridge returns 5% 
    (instead of 61%).
    Anyone seen this before or can explain it?
    
    2) The concentrator counters don't seem to reflect what is going on the
    fddi ring (ok this is a decconcentrator question)
    
    Thanks
    Mike
