> # Configuring Per Port Monitoring using Device Manager

> The configurable monitor per port option gives statistics for in and out traffic on that port, errors, class 2 traffic and other data that can be graphed over a period of time to give a real-time view into the performance of the port.

> ## DETAILED STEPS

> 1. Click the Device tab.
> 2. Right-click the port you are interested in and choose Monitor from the drop-down menu.

> You see the port real-time monitor dialog box.

> 3. Select a value from the Interval drop-down list to determine how often data is updated in the table shown here.
> 4. Click a statistical value in the table then click one of the graphing icons to display a running graph of that statistic over time. You see a graph window that contains options to change the graph type.

> Tip You can open multiple graphs for statistics on any of the active ports on the switch.
