For automatic reassignment of licenses, the following rules apply:
1. Auto License must be enabled for each feature license that you want to reassign automatically.
Feature licenses that do not have Auto License enabled, cannot be reassigned automatically.
2. If licenses for a feature are available for use, a license from these free licenses is assigned to the new
tri-radio sensor added to your Extreme AirDefense managed network.
3. If no licenses are available for assignment, then the following logic is used to select a license for
reassignment.
a. Extreme AirDefense searches for orphaned devices within your network. If an orphan device is
found, its license is released and added as a re-assignable license. This license is then used for the
newly added tri-radio access point.
Orphans are those devices that are no longer managed/monitored by Extreme AirDefense.
However, licenses on these devices are not immediately remove but retained for future use. At a
later date, when these devices are brought back online, these retained licenses are considered
valid by Extreme AirDefense and the devices are joined to the network without consuming
additional licenses. For more information on how to manually remove licenses from such
orphaned devices, see Manage License Manually on page 307.
b. When there are no orphaned devices within the network, Extreme AirDefense scans for and
collects a list of all sensors that are considered oine. For Extreme AirDefense, an oine sensor
is one that has not reported back to it for a duration of at least six (6) hours.
From this list of oine sensors, Extreme AirDefense releases the license of the sensor that has
been oine for the maximum duration. This license is then reassigned to the newly added tri-
radio access point.
The Auto Reassignment switch is only enabled when you set the Enable Configuration to the ON
position. By default, the Auto Reassignment switch is OFF. You must manually set this switch to the ON
position to use Auto License Reassignment.
Auto License Management
Auto-Licensing allows you to select licenses to be assigned to devices upon discovery.
You may define Auto-Licensing at the appliance network level all the way down to the floor network
level, but the best practice is to always define Auto-Licensing at the appliance level. Any network level
below the appliance level will inherit the configuration. If you need to have a dierent configuration
below the appliance level, use the Override settings option for the selected level.
The Override settings option is available when you select (highlight) a network level below the
Appliance level. Use the Expand icon in the Structure & Tags pane to reveal the other levels. By
default, the licenses settings are inherited from the level above the current level.
When applying Auto Licensing the following rules apply:
• Only selected licenses, those explicitly selected by using the option control next to that license, are
assigned automatically
• You can narrow the scope of the license by selecting the network level from the Structure & Tags
pane.
