Port Utilization

The Port Utilization screen shows the number of packets transmitted and received per second and calculates the percentage of the total available bandwidth being used on the port (displayed under %Util.).

To view the port utilization:

Highlight Port Utilization on the Network Monitoring Menu and press Enter.

Figure 6-90. Port Utilization screen

	Parameter	Description
	Port	The switch’s port number.
	Interval:<2 sec>	The time between updates received
		from the switch. Suspend stops the
		updates. The default is 2 seconds.
	TX/sec	The rate at which the given port is
		transmitting packets, in packets per
		second.
	RX/sec	The rate at which the given port is
		receiving packets, in packets per
		second.
	%Util	The percentage utilization of the
		given port’s available bandwidth.
