It is useful to be able to clear all counters and statistics without rebooting the switch when troubleshooting network issues. The clear statistics global command clears all counters and statistics for all interfaces except SNMP.
You can also clear the counters and statistics for an individual port using the clear statistics <port-list> command.
clear statistics <<port-list> | global >
When executed with the <port-list> option, clears the counters and statistics for an individual port.When executed with the global option, clears all counters and statistics for all interfaces except SNMP. The show interfaces [<port-list>] command displays the totals accumulated since the last boot or the last clear statistics command was executed. The menu and web pages also display these totals.
SNMP displays the counter and statistics totals accumulated since the last reboot; it is not affected by the clear statistics global command or the clear statistics <port-list> command. An SNMP trap is sent whenever the statistics are cleared.
Note
The clearing of statistics cannot be uncleared.

Great tip. Only issue I have, is that the stat-reset isn’t reflected in the web interface on the switch.
Is there any way to clear the stats there too?
Thank you for your article! I really liked seen this.

Very good written post. It will be valuable to everyone who employess it, including yours truly
. Keep up the good work – i will definitely read more posts.
The clear statistics command only doesn’t truly clear the statistics of the port. It only clears the statistics from being displayed during the current session. Once you log out and back in, the statistics since reboot are still there. So a reboot is still required for a true clearing of port statistics.
