Use the License Configuration screen to manage your AirDefense licenses.
The License Configuration screen, in the new user interface, combines the activities performed from the and screens (from the legacy interface) into it.
The Auto-Licensing screen in the legacy user interface enables you to assign licenses automatically when a device is discovered. Similarly, the Appliance Licensing screen enables you to assign licenses to individual devices within your network tree.
The License Configuration screen is accessed from the menu path. The following screen displays.
The screen displays two panes. The Structure & Tags pane displays the tree of your AirDefense managed network. Use this pane to drill down to the particular device of interest when applying licenses. For more information about this pane, see View And Manage Your Network Tree
The License Configuration pane displays the list of all licenses available for this AirDefense instance. The License Configuration pane displays the following information.
| Field | Description |
|---|---|
| Appliance ID/Key | The unique key or ID assigned to this AirDefense appliance. This ID cannot be
modified or removed. This key is required to
generate any license that you purchase for use with
this AirDefense appliance. Select the
icon to copy this Appliance ID/Key to
your PC's clipboard. Select the 
icon to download the Appliance ID/Key to
a text file. |
| Licensed Feature | The number of licensed featured installed in this AirDefense instance. This field also shows the total number of available AirDefense features. |
| Total Licenses Used | The count of licenses used by this AirDefense instance. |
The list of licenses that are available for this AirDefense instance is also displayed.
For each license, a colored dot indicates the state of the license.
The small 
icon located
to the right of the License Configuration
label displays a brief explanation of all
the icons displayed on this screen. When you hover over this
icon, the following popup displays.
You can order a feature's license multiple times to meet your deployment's requirements. Each time you purchase a license for a particular feature, it is recorded separately under that feature's license.
To view a feature's license orders, click on its label. The label expands and displays all the orders for the selected feature. When expanded, this area displays the details of each license ordered. This area also displays a color dot indicating the current state of validity of each license order.
The following information is shown for each order.
A colored dot indicates the validity state of the order. The following is a list of the various states of the order.
The Enable Configuration switch is only available when the top most node of the Structure & Tags pane is selected. Auto Licenses can only be applied when this switch is set to ON and remains ON. The top most node is always named ADSP and you must use this switch to enable Auto Licensing through out the AirDefense system.
By default, any level in the Structure & Tags pane always inherits the licenses 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 licenses from the top node. However, you can override the inherited licenses at any level in the hierarchy.
To override the inherited licenses, in the Structure & Tags
pane, select the node where you want to override the inherited licenses. Then from
the 
control, select the Override option. Note
that the Inherited from
: control always displays the name of the level from which the
licenses are inherited from. Use this information to orient your self on how the
licenses are inherited.
Change the licenses for the selected level as required and then use the APPLY button to implement the modified license settings. These licenses will now be inherited by all levels below the selected level unless a sub-level has been explicitly overridden.
License Auto Reassignment enables you to manage your license reassignments without manual intervention. Generally, licenses are manually reassigned from any online, offline, or orphan device within your network to those devices that are added to your network. When reassigning a license manually, you would remove the license from an existing device and move it to the new device. This feature does this action automatically if you have enabled it and have adequate number of reassignment licenses that you can use.
Important
License Auto Reassignment works for those licenses that have enabled Auto License. For more information, see Auto License Management.
When you purchase a feature license, you are also provided with a few reassignment licenses which you can use as required. Reassignments of license is generally done when a device is being replaced with a newer model or when you are reallocating assets between various sites that you manage.
Important
Please note that, at present, we support license reassignment for the following tri-radio access points: AP 410i, AP 410e, AP 460i, and AP 460e.
For automatic reassignment of licenses, the following rules apply:
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.
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.
If no licenses are available for assignment, then the following logic is used to select a license for reassignment.
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.
When there are no orphaned devices within the network, Extreme AirDefense scans for and collects a list of all sensors that are considered offline. For Extreme AirDefense, an offline sensor is one that has not reported back to it for a duration of at least six (6) hours.
From this list of offline sensors, Extreme AirDefense releases the license of the sensor that has been offline 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.
