Viewing Port Utilization

Port utilization measures the amount of traffic passing through a port over a period of time. For example, if an initiator is transmitting data to a target, the initiator port displays a port utilization value (%) while the target port does not. If the same initiator is receiving data from the target, the target port displays a port utilization value (%) while the initiator port displays does not.

The Port Utilization page displays each port’s utilization percentage based on high, average, and low utilization.

Value	Description

High	The highest percentage of data communication through a port over a period
	of time (measured in seconds).

Average	The average percentage of data communication through a port over a
	period of time (measured in seconds).

Low	The lowest percentage of data communication through a port over a period
	of time (measured in seconds).

To change the port utilization interval:

Click Advanced Functions > Thresholds > Switch. See “Adjusting the Switch Thresholds” on page 28 for additional information.

To view port utilization:

Click Port > Utilization.

The Port Utilization page appears.
