Viewing statistics on a regular basis allows you to see how well your network is performing. If you
keep simple daily records, you can see trends emerging and notice problems arising before they cause
major network faults. In this way, statistics can help you get the best out of your network.

Status Monitoring

The status monitoring facility provides information about the switch. This information may be useful
for your technical support representative if you have a problem. ExtremeWare XOS includes many
command line interface (CLI)
and facilities.
NOTE
For more information about show commands for a specific ExtremeWare XOS feature, see the appropriate chapter in
this guide.

Viewing Port Statistics

ExtremeWare XOS provides a facility for viewing port statistical information. The summary information
lists values for the current counter for each port on each operational module in the system; and the
display is refreshed approximately every two seconds. Values are displayed to nine digits of accuracy.
To view port statistics, use the following command:
show ports <port_list> statistics
