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).
