User Guide: AT-RADGate for VST-APL/VST-VRT version 1.1.1

# Installing Licenses

## Basic operation of Licenses

You have to install proper licenses before you start using AT-RADgate.

- The RADIUS Authentication feature does not work until the license is installed.
- A license bundles the right to register a certain number of User or Endpoint policies. The number of User and Endpoint policies that can be registered cannot exceed this number.

The license controls the number of RADIUS Authentication functions and Authentication policies, User policies, and Endpoint policies that can be registered. If at least one valid license is installed, the RADIUS Authentication feature is enabled. In addition, each license has a set number of units, and you can register User policies and Endpoint policies up to the total number of valid license units installed. (The total number of User policies and Endpoint policies must not exceed the total number of units.)

> Note

> > If you do not have a license file, contact our sales engineer.
> > To obtain the license file, you need the AT-RADgate Serial Number displayed on the System Management > About page.

> Note

> > For the license, also refer to References > System Management > License.

##### Trial License

If you have not received the official license yet or if you want to try out AT-RADgate, you can use the trial license. The usage rights granted to the trial license are as follows:

Table 1: Trial License
Expiry Date | 90 days
Number of Units | 200,000

> Note

> > When you install a regular license, any trial licenses that you have installed as well as any trial licenses that you have not installed are deactivated. Therefore, you cannot install an unused trial license after your regular license has expired. To continue using AT-RADgate, purchase an update license.

## About the validity period of the License

The license for this product has a valid period.
License expiration date checks are performed between 00:00:00 and 00:05:59 of AT-RADgate system time and when AT-RADgate is started.
As a result of the check, expiration warning messages is displayed in the log 28 days, 21 days, 14 days, 7 days, and 1 day before the license expiration date.

> Note

> > You can also send deadline warning messages via email. Configure the following settings.
> > - Set the SMTP Server (Email Settings page)
> > - Register an Email Address to your account (Account Management page)
> > - Grant the account the permission to "Allow to configure system settings" (Account Management page)

If any of the following conditions occur, the RADIUS Authentication function stops and a message is displayed at the top of the settings page notifying you that the license is invalid.

- When some licenses have expired and the number of registered policies exceeds the permitted number granted by the license.
- If all licenses have expired

If you install a valid license and the abnormal license condition is resolved, the disabled function is enabled and the message disappears.

## About reissue of license

The issued license is tied to the AT-RADgate Serial Number.
In the following cases, the AT-RADgate Serial Number has changed and the issued license cannot be used and must be reissued. Make a note of the Serial Number displayed on the System Management > About page and contact our sales engineer.

- Remove the AT-RADgate application on the VST-APL or VST-VRT and reinstall it.
- Restore (migrate) the AT-RADgate application to VST-APL in another chassis
- Restore (migrate) the AT-RADgate application to VST-VRT on another virtual machine

However, if you have a file backed up using "System Backup" on the System Management > About page, you can use "System Restore" on the System Management > About page to completely restore the system before migration, including license information.
Note that the Windows Active Directory settings configured on the RADIUS Management > Active Directory Settings page are not included in the backup file, so you need to reconfigure them after performing a system restore.
