Description
Opens the window for an existing graph. You can change the back-
ground image or graph scale. To change the name of the graph, you
must create a new graph.
Deletes the active graph. When you select this item, a dialogue box
appears to confirm that you want to delete the graph.
Lists the available background images and allows you to delete any
available image.
Allows you to change the view of the ungraphed components in the
panel on the left:
• Tab View—Shows one type of component at a time, organized
by tabs.
• List View—Shows all three types of components in the left
panel.
Figure 75 on page 166 shows the difference between the tab view
and list view.
Select the power range image to display for a managed AP:
• Disable Power Display—The power range image is not
displayed
• Show 802.11 a—Shows the transmit power for all managed
APs that have a radio operating in 802.11a mode.
• Show 802.11 b/g—Shows the transmit power for all managed
APs that have a radio operating in 802.11 b/g mode.
The size of the power range image is based on the transmit power
for the radio, which can be low, medium, or high. The size of the
power range image also depends on the actual scale factor of the
current background image.
If the AP has two radios that are configured in the same mode, two
power range images are displayed.
NOTE: The color of the power range image is based on the assigned
channel of the associated radio.
If two APs use the same channel (or channels that are close together)
and are within each other's transmission range, the APs will
interfere with each other and wireless clients will experience poor
WLAN performance. To reduce interference, you can take one of
the following steps:
• Reduce the transmit power on the APs.
• Physically place the APs further apart.
• Use the automatic channel adjustment algorithm on the APs or
statically set the channels so they are non-interfering channels.
CAUTION: Power ranges are for illustrative purposes only. The
actual power distribution varies based on factors such as office wall
propagation and background RF noise.
