Overriding Configuration Settings
The Enable Configuration switch is only available at the top most node of the Structure & Tags pane.
Configurations can only be applied when this switch is set to ON. The top most node is always named
ADSP and you must use this switch to apply the selected configuration through out the Extreme
AirDefense system.
By default, any level in the Structure & Tags pane always inherits configuration from the level above it
unless explicitly overridden.
Since Extreme AirDefense manages its devices using a hierarchy that is configured using the Structure
& Tags pane, all the nodes under the top ADSP node inherit the configurations set at that node.
However, you can override the inherited configuration at any level in the hierarchy.
To override the inherited settings, in the Structure & Tags pane, select the node where you want to
override the inherited configuration. Then from the
control, select the
Override option. Note that the Inherited from : control always displays the name of the level from
which the configuration settings are inherited from. Use this information to orient your self on how the
configurations are inherited.
Change the configuration for the selected level as required and then use the APPLY button to
implement the modified configuration settings. These settings will now be inherited by all levels below
the selected level unless a sub-level has been explicitly overridden.
Operation Tab
The following operations can be performed from the Operation tab of the Sensor Manager screen.
• Scan Mode - Use this control to set the channels to scan for unsanctioned devices. AirDefense
provides a comprehensive list of scan modes that you can apply to your AirDefense managed
network.
• Scan Settings - Use this control to set the various parameters associated with scanning and other
security related settings.
• Spectrum Settings - Use this control to set the threshold values for Advance Spectrum Analysis In-

Scan Mode Settings
Use the Scan Mode control to choose the channels to monitor for rogue devices. AirDefense provides a
set of preconfigured list of channels to scan.
The following pre-configured scan modes are available for use:
• Default Scan - This is list of channels that are scanned by default. This list consists of all the standard
channels in both the 2.4 GHz and 5.0 GHz bands. This list cannot be edited.
• Extended Channel Scan - This list consists of all the standard channels in the 2.4 GHz and 5.0 GHz
bands and also includes the extended channels in these bands. This list cannot be edited.
• Extended and Emergency Channel Scan - This list consists of all standard, extended, and emergency
channels in both the 2.4 GHz and 5.0 GHz bands. This is most comprehensive of all the pre-
configured scans. This list cannot be edited.
