Citrix ADC SDX

SDX licensing overview

In the Citrix NetScaler SDX Management Service, you can use your hardware serial number (HSN) or your license activation code (LAC) 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.


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

  1. You must be able to access public domains through the appliance. For example, the appliance should be able to access The license allocation software internally accesses the Citrix licensing portal for your license. To access a public domain, you must configure the Management Service IP address and set up a DNS server.
  2. Your license must be linked to your hardware, or you must have a valid license activation code (LAC). Citrix sends your LAC by email when you purchase a license.

Allocate your license by using the Management Service

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 activation code (LAC).

You can partially allocate licenses as required for your deployment. For example, if your license file contains ten licenses, but your current requirement is for only six licenses, you can allocate six licenses now, and allocate additional licenses later. You cannot allocate more than the total number of licenses present in your license file.
