Port Statistics screen

The Port Statistics screen (Figure 66) allows you to view detailed information about any switch or port in a stacked or standalone configuration. The screen is divided into two sections (Received and Transmitted) so that you can compare and evaluate throughput or other port parameters. All screen data is updated approximately every 2 seconds.

You can use the Port Statistics screen to clear (reset to zero) port counters for a specific switch or port. Alternatively, you can use the Clear All Port Statistics option to clear port counters for all switches or ports (see “Switch Configuration Menu screen” on page 103).
