l When you apply evaluation license keys on a controller, abnormal tampering of the device’s system clock
(such as setting back the system clock) results in the disabling of software licensed modules and their
supported features. This can affect network services.
l The Advanced Cryptography (ACR) license includes the following caveats:
n On a platform that supports 2048 IPsec tunnels, the maximum number of Suite B IPsec tunnels
supported is 2048, even if a larger capacity license is installed.
n ACR licenses are cumulative. For example, if you want to support 2048 Suite B connections, you can
install two ACR licenses that support 1024 connections each.
n If your controller uses an ACR license that allows fewer IPsec tunnels that is supported by that controller
platform, that controller can still support IPsec tunnels using non-Suite B modes (for example, AES-CBC),
up to the platform maximum.
n The ACR license allows a controller to use both IPsec Suite B and 802.11i Suite B connections
simultaneously. The combined number of these sessions may not exceed the ACR license maximum.
n A single client using both 802.11i Suite B and IPsec Suite B connections will simultaneously consume two
ACR licenses.
ArubaOS provides the ability to move a license from one standalone controller to another, for maximum flexibility in
managing an organization’s network and to minimize an RMA impact. Dell monitors and detects license fraud.
Abnormally high volumes of license transfers for the same license certificate to multiple controllers can indicate a
breach of the Dell end user software license agreement and will be investigated.
Centralized Licensing Overview
In order to configure a license-dependent feature on the local controller, the master controller(s) must be
licensed for each of the features configured on the local controllers. Centralized licensing simplifies licensing
management by distributing licenses installed on one controller to other controllers on the network. One
controller acts as a centralized license database for all other controllers connected to it, allowing all controllers
to share a pool of unused licenses. The primary and backup licensing servers can share a single set of licenses,
eliminating the need for a redundant license set on the backup server. Local licensing client controllers
maintain information sent from the licensing server, even if the licensing client controller and the licensing
server controller can no longer communicate. If an AP fails over from one client controller to another, the AP
will be allowed to come up even if there aren’t sufficient licenses present on the backup controller. the APs
continue to stay active until they reboot. However, if there are not sufficient available licenses to bring up an
AP after it reboots, that AP will not become active.
You can use the centralized licensing feature in a master-local topology with a redundant backup master, or in a
multi-master network where all the masters can communicate with each other (for example, if they are all
connected to a single W-AirWave server). In the master-local topology, the master controller acts as the primary
licensing server, and the redundant backup master acts as the backup licensing server. In a multi-master
network, one controller must be designated as a primary server, and a second controller must be configured as
a backup licensing server.
Centralized licensing can distribute the following license types:
l AP
l PEFNG
l RFProtect
l xSec
l ACR
