NetScaler VPX check-in and check-out licensing

You can allocate VPX licenses to NetScaler VPX instances on demand from NetScaler MAS. The Licenses are stored and managed by NetScaler MAS, which has a licensing framework that provides scalable and automated license provisioning. A NetScaler VPX instance can check out the license from the NetScaler MAS when a NetScaler VPX instance is provisioned, or check back in its license to NetScaler MAS when an instance is removed or destroyed.

Prerequisites

Make sure that the following prerequisites are met:

  • You are using a NetScaler VPX image running software version 12.0.
    For example: NSVPX-ESX-12.0-xx.xx_nc.zip
  • You have installed NetScaler MAS running version 12.0.
    For example: MAS-ESX-12.0-xx.xx.zip

Note

To manage existing VPX licenses by NetScaler MAS, you need to rehost the licenses to NetScaler MAS.

Installing Licenses in NetScaler MAS

Note: Before installing licenses, restart the NetScaler MAS virtual appliance if you have changed the software edition or bandwidth.

To install license files on the NetScaler Management and Analytics System:

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

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

  3. Navigate to Networks > Licenses.

  4. In the License Files section, select one of the following options:

    • Upload license files from a local computer - If a license file is already present on your local computer, you can upload it to the NetScaler MAS.
      To add license files, click Browse and select the license file (.lic) that you want add. Then click Finish.

    • Use license access code - Citrix emails the License Access Code (LAC) for the licenses that you purchase.
      To add license files, enter the LAC in the text box and then click Get Licenses.

    Note: Make sure you are connected to internet before using LAC code for installing the licenses.

Configure Expiry Checks for NetScaler VPX Check-In/ Check-Out Licenses

You can now configure license expiry threshold for NetScaler VPX licenses. By setting thresholds, NetScaler MAS sends notifications via email or SMS when a license is due to expire. An SNMP trap and a notification is also sent when the license has expired on NetScaler MAS.

An event is generated when a license expiry notification is sent and this event can be viewed on NetScaler MAS.

To configure license expiry checks:

  1. Navigate to Networks > Licenses.

  2. In the License Settings page, under the License Expiry Information section, you can find the details of the licenses that are going to expire:

    • Feature: Type of license that is going to expire.

    • Count: Number of virtual servers or instances that will be affected.

    • Days to expiry: Number of days before license expiry.

  3. In the Notification Settings section, click the Edit icon and specify the alert threshold. You can set a percentage of pooled licenses capacity to be used to notify administrators.

  4. Choose the type of notification you want to send by selecting the appropriate check box. The notification types are as follows:

    1. Email Profile: Specify a mail server and profile details. An email is triggered when your licenses are about to expire.
