Metered Licensing Management

1 Introduction

Metered Enterprise Licensing Agreement (MELA) offers enterprises and service providers a flexible way to license their application delivery resources. MELA meets the demands for flexible application capacity and the requirements of environments such as cloud for multiple Application Delivery Controller (ADC) instances. By using this model, an organization subscribes to a defined monthly capacity that can be distributed across unlimited on-demand ADC instances deployed between multiple cloud and on-premises environments. MELA is a subscription service and enables organizations to pay-as-you-grow with an application delivery infrastructure that is flexible, cost-effective, scalable and always right-sized.

By using the KEMP 360 Central local licensing functionality, you can quickly and easily activate KEMP LoadMaster Virtual Appliances using MELA. This licensing method enables flexible operational and deployment models to be supported instead of the standard single LoadMaster licensing model.

1.1 Document Purpose

The aim of this document is to walk you through a successful deployment of MELA from purchasing a MELA contract from KEMP to activating the LoadMaster using KEMP 360 Central.

1.2 Intended Audience

This document is intended for MELA customers who want to find out how to deploy their KEMP 360 Central and LoadMaster instances.

When we refer to KEMP 360 Central and LoadMasters throughout this document, we are referring to the MELA image.

2 Register for a KEMP ID

A KEMP ID is required for licensing. The first stage in doing a successful deployment of MELA is to register for a KEMP ID (if you do not already have one). To register for a KEMP ID, perform the following steps:

1. Go to the KEMP registration page at https://kemptechnologies.com/kemp-id-registration/

image1.png

2. Complete the form as required.

Ensure you enter a valid email address. The validation email and license information is sent to this email address.

3. Make note of your password because it is required to activate the account.

4. Click Create a KEMP ID. An email is sent from KEMP to the address specified in the form.

5. Open the email and click Confirm to open the validation screen.

If you do not activate the account within 24 hours of registering, the record is deleted and you must register again.

6. Enter the password that you specified on the registration form.

7. Click Activate Now. You then receive a further confirmation email to inform you that your KEMP ID is now active.

8. Contact KEMP to convert your KEMP ID to a MELA KEMP ID.

This KEMP account can now be used to activate products.

2.1 Purchase a MELA Contract from KEMP

Contact your KEMP representative directly to purchase a MELA contract.

This is important because you must have a MELA contract before you can use MELA licensing and functionality.

After you do this, KEMP sends you a contract ID.

2.2 Reset your KEMP ID Password

If you do not know the password for your KEMP ID account, you can reset it. To reset the KEMP ID password, follow the steps below:

1. Go to the reset password page: http://kemptechnologies.com/support/reset-password

2. Enter your KEMP ID.

3. Click the Submit button. An email is sent to the address specified.

4. Click the link in the email.

5. Enter the new password in both the Password and Retype Password fields.

6. Click Reset. A message appears informing you that the password is successfully changed.

2.3 Changing your KEMP ID Email Address

If your email address or any other details associated with your KEMP ID must be changed for any reason, contact KEMP Technologies who can update the record.

3 Deploy a KEMP 360 Central MELA Instance

Refer to the relevant KEMP 360 Central installation guide depending on your environment. You can find all documents at https://kemptechnologies.com/documentation.

4 Activate your KEMP 360 Central License

For instructions on how to license KEMP 360 Central, refer to the KEMP 360 Central Feature Description on the KEMP Documentation Page.

4.1 Licensing Complete

Having successfully licensed your KEMP 360 MELA, the initial configuration is now complete. For further information, including instructions on how to add a network to KEMP 360 Central, refer to the KEMP 360 Central Feature Description

5 Deploy a MELA LoadMaster

Refer to the relevant LoadMaster installation guide depending on your environment. You can find all documents at https://kemptechnologies.com/loadmaster-documentation/.

When you get to the steps for licensing your LoadMaster, refer back to this document because the licensing steps differ when using MELA.

6 License a LoadMaster using KEMP 360 Central

When a locally licensed LoadMaster is initially deployed, a screen appears asking if you want to use Online Licensing or KEMP 360 Central Licensing (this was called Local Activation on pre-7.2.43 LoadMasters). Select KEMP 360 Central Licensing.

When you select KEMP 360 Central Licensing, the screen above appears. If this screen does not appear, you are not using the correct version of the LoadMaster. Contact a KEMP representative if this is the case.

The KEMP 360 Central (with local licensing enabled) details must be configured in the LoadMaster web User Interface (UI) so the LoadMaster can contact KEMP 360 Central. Follow the steps below to activate the LoadMaster:

1. Type the hostname of KEMP 360 Central in the Host text box.

If Network Address Translation (NAT) is being used between your LoadMaster and KEMP 360 Central (for example, your LoadMaster is located in a public cloud), ensure that the IP address in the device settings is the publicly accessible IP address.

2. Type the Port to access KEMP 360 Central on.

If using Azure, change the Port setting to 8443. The internal IP address and host name are found in the Dashboard screen of the KEMP 360 Central instance. The hostname is based on the instance name, which is specified when originally creating the instance. If you are not using Azure, the default hostname is K360Central.

3. Click Activate. The available license types are displayed.

4. Select the relevant license type and click Continue.

5. The LoadMaster is now licensed against the local licensing feature of KEMP 360 Central.

7 Add the LoadMaster to KEMP 360 Central Management

The LoadMaster must be connected to KEMP 360 Central to enable Metered Licensing. To do this, complete the following steps in KEMP 360 Central:

1. Click the cloud icon on the left then click All Networks.

2. Select the relevant LoadMaster.

3. Click the Edit icon in the bottom-left.

4. Enter the Public Access Address for KEMP 360 Central.

5. Enter the Port used to communicate with the LoadMaster.

6. Type a nickname in the Nickname field (if required).

7. Enter the Username and Password used to access the LoadMaster.

8. Type an Alternative WUI Access address in the field provided (this is optional).

9. Click Apply.

Once added for management, the LoadMaster icon turns blue.

KEMP 360 Central keeps track of the activated systems by maintaining a list of activated VLMs and MAC addresses. This list can be accessed by clicking the cog icon and selecting Metered Licensing Management. Ensure the MAC addresses of the VLMs are unique by checking the VLM hardware options through a hypervisor. This enables proper tracking of the VLMs. If the license limit of VLMs is reached, KEMP 360 Central will not activate any more VLMs. If the limit is reached, a warning message appears on screen and an existing active VLM instance must be unlicensed (deregistered) before a new VLM can be licensed.

The LoadMaster periodically checks for the presence of the local license (KEMP 360 Central). If the local license cannot be found, or there are any errors, an error message is displayed and the VLM stops working after a predetermined length of time based on your agreement with KEMP. If an activation check fails, an error message appears on the LoadMaster home screen indicating that activation failed.

8 Troubleshooting

If you try to license and there are issues, a number of checks are performed automatically and the results and associated error message are displayed.

These checks perform the following tasks:

  • Ping Default Gateway
  • Ping DNS Servers
  • Ping Licensing Server
  • Ping Activation Server

You can also manually check the KEMP 360 Central debug log. If there are no entries relating to Activation Server, it means the connection to the Activation Server has failed.
