Using the "MefSoamDmCurrentStatsEntry" (iso.184.108.40.206.1.15007.1.3.1.3.4.1.) to monitor the values of the CFM statistics.
That are the statistic values that we show with "show cfm segment frame-delay statistics"
t seems that the given value is completely wrong as soon the "iso.220.127.116.11.1.15007.1.3.1.18.104.22.168.22.214.171.124 = mefSoamDmCurrentStatsElapsedTime" has reached the value of 60000. (10 minutes)
From that time only the "mefSoamDmCurrentStatsFrameDelayTwoWayMin" is showing an accurate value.
If you give the command "clear counters cfm segment all" the values will be accurate for the next 10 minutes.
