Table 30 describes the various monitoring modes available from the Port
Mirroring Configuration screen.
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 ).

Unit/Port X Indicates one of the ports (of the specified unit) that will be monitored by the
designated port monitor when one of the port-based monitoring modes is selected.
This port will be monitored according to the value of Port X in the Monitoring Mode
field (see
Table 30 ).
