This chapter describes how to view the current operating status of the
Switch, how to display information in the Switch log, and how to take
advantage of the RMON capabilities available in the Switch.
Viewing statistics on a regular basis allows you to:
■
Monitor how well your network is performing
■
Monitor emerging trends and notice problems arising before they
cause major network faults
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.
