VLAN Statistics represents the information as a horizontal bar chart. Using this tool in conjunction with Port Statistics and Switch Statistics makes it straightforward to discover the cause of a problem.

You could then use Port Statistics to help indicate from which port the problem originates.

Alarms and Events Overview

The Alarms and Events tool reports when a specified counter on selected ports, or on a device, cross user defined thresholds. The Alarm Wizard provides a simple method for defining upper and lower thresholds of a counter on selected ports or on the device. This definition of the thresholds is an Alarm.

An Event is the crossing of a defined threshold in the direction it was defined. For example, a Rising Event is when the rate of a specified counter on a selected port rises above the defined Rising (upper) Threshold. A Falling Event is when the rate of a specified counter on a selected port falls below the defined Falling (lower) Threshold.

The following figure shows the scheme used to generate Events.
