3 Click OK to save the test.
To confirm that the test is running, click Link Test to return to the Link Test table. Scroll the table
columns to the right to view the Status column. When the test begins, the column displays the
message: Link Test Active. Continue to refresh the display until you see the message: Link
Test Completed Successfully.
Other recommendations for running a link test:
• Set the test duration to be greater than five minutes (or equivalent number of packets, for
example five minutes = 1200 packets), and set the averaging interval greater than 30 seconds.
This compensates for any momentary glitches in the wireless link.
• Generate traffic (such as ping traffic) to the station when performing the link test. If rate
adaptation is active, this helps the uplink and downlink data rates settle at the maximum
sustainable rates for that link.
A maximum of 10 link tests can be active on an AP at one time. The collected link test data is
retained even after the link test is finished, until manually deleted.
To graph the results of a link test, select the test on the Link Test tab, and click Graph. The Graph
panel (Figure 68) opens. Only one graph can be displayed at a time.
Field Description
Interface Select the AP radio.
Station MAC Select the MAC address of the station included in the link test.

Average Interval Enter the interval over which link test data such as signal strength or signal
quality is averaged.
NOTE: When the link test is first invoked, the Java Applet will post a standard Java
security warning. Accept the warning to continue. A single link test graph can be
