Table 30 describes the various monitoring modes available from the Port
Mirroring Configuration screen.
Port Statistics screen
The Port Statistics screen ( Figure 71 ) allows you to view detailed information
about any switch or port in a 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 108 ).
To open the Port Statistics screen:
Port X Indicates one of the ports 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 ).
Default Value Zero-length string
