> # Configuring the Summary View in Device Manager

> ## DETAILED STEPS

> 1. Click the Summary tab on the main display.

> You see all of the active ports on the switch, as well as the configuration options available from the Summary view .

> 2. Choose a value from the Poll Interval drop-down list.
> 3. Decide how you want your data to be interpreted by looking at the Show Rx/Tx drop-down menu. The table updates each polling interval to show an overview of the receive and transmit data for each active port on the switch.
> 4. Select a value from the Show Rx/Tx drop-down list. If you select Util%, you need to also select values from the two Show Rx/Tx > %Util/sec drop-down lists. The first value is the warning level and the second value is the critical threshold level for event reporting.

> Note that you can also display percent utilization for a single port by selecting the port and clicking the Monitor Selected Interface Traffic Util % icon.
