Showing Port Statistics

You can display statistics on network traffic from the ports. These statistics can be

used to identify potential problems with the switch (such as a faulty port or unusually

heavy loading). All values displayed have been accumulated since the last system

reboot, but can be reset to zero by clicking the CLEAR button. The current statistics

are not displayed until you click the REFRESH button.
