Apply Environment Monitoring Configuration
If you need to apply a dierent set of Environment Monitoring configurations at a specific level in your
Extreme AirDefense hierarchy, navigate to the level in Structure & Tags pane and select it. Use the
control's Override option to apply the alternate configuration at
that level.
For more information see the section Overriding Configuration Settings in this document.
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.
