Citrix ADC licensing overview 编辑

The process of allocating your Citrix ADC licenses has been greatly simplified. The new licensing framework allows you to focus on getting maximum value from Citrix products.

In the Citrix ADC 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.

Note: Purchase separate licenses for each appliance in a high availability pair. Ensure that the same types of licenses are installed on both the appliances. For example, if you purchase a Premium license for one appliance, you must purchase another Premium license for the other appliance.

Prerequisites

To use the hardware serial number or license access code to allocate your licenses:

• You must be able to access public domains through the appliance. For example, the appliance should be able to access www.citrix.com. The license allocation software internally accesses the Citrix licensing portal for your license. To access a public domain:

  • Use a proxy server or set up a DNS server.
  • Configure a Citrix ADC IP (NSIP) address or a subnet IP (SNIP) address on your Citrix ADC appliance.

• Your license must be linked to your hardware, or you must have a valid license access code. Citrix sends your license access code by email when you purchase a license.

Allocate a license by using the GUI

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.

To allocate your license

1. In a web browser, type the IP address of the Citrix ADC appliance (for example, http://192.168.100.1).

2. In User Name and Password, type the administrator credentials.

3. On the Configuration tab, navigate to System > Licenses.

4. In the details pane, click Manage Licenses, click Add New License, and then select one of the following options:

   • Use Serial Number. The software internally fetches the serial number of your appliance and uses this number to display your licenses.

   • Use license access code. Citrix emails the license access code for the license that you purchased. Enter the license access code in the text box.

     If you do not want to configure internet connectivity on the Citrix ADC 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.

5. Click Get Licenses. Depending on the option that you selected, one of the following dialog boxes appears.

   • The following dialog box appears if you selected Hardware Serial Number.

     

   • The following dialog box appears if you selected license access code.

     

6. Select the license file that you want to use to allocate your licenses.

7. In the Allocate column, enter the number of licenses to be allocated. Then click Get.

   • If you selected Hardware Serial Number, enter the number of licenses, as shown in the following screenshot.

     

   • If you selected license access code, enter the number of licenses, as shown in the following screenshot.

     

8. Click restart for the license to take effect.

9. In the restart dialog box, click OK to proceed with the changes, or click Close to cancel the changes.

   

Install a license

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 a license file by using the GUI

1. In a web browser, type the IP address of the Citrix ADC appliance (for example, http://192.168.100.1).
2. In User Name and Password, type the administrator credentials.
3. On the Configuration tab, navigate to System Licenses.
4. In the details pane, click Manage Licenses.
5. Click Add New License, then select Upload license files from a local computer.
6. Click Browse. Navigate to the location of the license files, select the license file, and then click Open.
7. Click restart to apply the license.
8. In the restart dialog box, click OK to proceed with the changes, or click Close to cancel the changes.

To install the licenses by using the CLI:

1. Open an SSH connection to the ADC appliance by using an SSH client, such as PuTTY.

2. Log on to the ADC appliance by using the administrator credentials.

3. Switch to the shell prompt, create a license subdirectory in the nsconfig directory, if it does not exist, and copy one or more new license files to this directory.

   Example

   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/license
