22.214.171.124 FC_MR-4 Statistics Window
The statistics window lists parameters at the line level. The Statistics window provides buttons to change
the statistical values shown. The Baseline button resets the displayed statistics values to zero. The
Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic
refresh occurs. The Statistics window also has a Clear button. The Clear button sets the values on the
card to zero. All counters on the card are cleared.
