Resetting the Statistics Counters
You reset statistics counters because:
The counters no longer reflect the current information.
For example, disabling a port to fix a problem does not reset its
counters. After the error clears and you manually re-enable the
port, you may want its statistics to accumulate from a fresh start.
Otherwise, the counters and graphs will reflect information
associated with the error condition and the counters will continue
to increment from the wrong baseline.
As each frame type reaches the maximum of 2
32
(over 4 billion),
the statistics for that frame type resets to zero. Once this happens,
the counters and graph become inaccurately skewed.
To reset switch (system) counters, perform the following procedure:
1. From the Main Menu, select the switch whose counters are to be reset
to 0 (zero).
2. From the Main Menu, select Ethernet Statistics.
3. Select Zero all statistics on the entire system.
Both the receive and transmit counters and graphs are reset to 0 (zero).
