The process of allocating your NetScaler licenses has been greatly simplified. The new licensing framework allows you to focus on getting maximum value from Citrix products.
In the NetScaler GUI, you can use your hardware serial number (HSN) or your license access code to allocate your licenses. Alternatively, if a license is already present on your local computer, you can upload it to the appliance.
For all other functionality, such as returning or reallocating your license, you must use the licensing portal. Optionally, you can still use the licensing portal for license allocation. For more information about the licensing portal, see http://support.citrix.com/article/CTX131110.
If your license is already linked to your hardware, the license allocation process can use the hardware serial number. Otherwise, you must type the license access code.
You can partially allocate licenses as required for your deployment. For example, if your license file contains 10 licenses, but your current requirement is for only six licenses, you can allocate six licenses now, and allocate more licenses later. You cannot allocate more than the total number of licenses present in your license file.
If you do not want to configure internet connectivity on the NetScaler appliance, you can use a proxy server. Select the Connect through Proxy Server check box and specify the IP address and port of your proxy server.
If you downloaded your license file to your local computer by accessing the licensing portal, you must upload the license to the appliance.
To install the licenses by using the CLI
login: nsroot Password: nsroot Last login: Mon Aug 4 03:37:27 2008 from 10.102.29.9 Done > shell Last login: Mon Aug 4 03:51:42 from 10.103.25.64 root@ns# mkdir /nsconfig/license root@ns# cd /nsconfig/licenseCopy one or more new license files to this directory.
Before using a feature, ensure that your license supports the feature.
sh ns license License status: Web Logging: YES Surge Protection: YES ....... HTML Injection: YES Done
When you use the NetScaler appliance for the first time, you must enable a feature before you can use its functionality. If you configure a feature before it is enabled, a warning message appears. The configuration is saved but it applies only after the feature is enabled.
