STATUS MONITORING AND

8 STATISTICS

This chapter describes how to view the current operating status of the switch, how to display information in the log, and how to take advantage of available Remote Monitoring (RMON) capabilities.

Viewing statistics on a regular basis allows you to see how well your network is performing. If you keep simple daily records, you will see trends emerging and notice problems arising before they cause major network faults. 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. The Switch 9100 includes many show commands that display information about different switch functions and facilities.

For more information about show commands for a specific Switch 9100 feature, refer to the appropriate chapter in this guide.
