# Adding and Removing Licenses

As a prerequisite, you must purchase a license key from your CTERA authorized reseller, specifying your portal's DNS suffix, antivirus requirements, and the number of required CTERA Edge Filers, server agents, and workstation agent licenses. You receive one or more license keys.

          **Note**

          

You can view your CTERA Portal's DNS suffix, in the global administration view's **Settings > Control Panel > Global Settings** page. This DNS suffix was set up when you installed the CTERA Portal, as described in the installation guide for your environment. To extend a trial license requires Internet access. If this is a problem, contact [CTERA support](http://ctera.com/support).

## Adding a License

**To add a license:**

1. In the global administration view, select **Settings > License** in the navigation pane.

3. Copy the license key you received from CTERA, and paste it into the text box.  

To add more than one key, paste each key on a new line.  

The system verifies and activates the license keys by contacting the CTERA Activation service. As each license key is activated, it is associated with this installation of CTERA Portal.
4. Optionally add a comment in the **Comment** field. The comment is displayed in the **License** page.
          **Note**

          

You can use this comment to document information such as the purchase order number associated with the license.
5. Click **Save**.

CTERA portal connects to the CTERA license server over HTTPS to activate the key.
