Ethernet statistics> Zero all statistics
on the entire system
You reset the 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 the graph not only still
reflect information associated with the error condition; the
counters 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.
