Before adding an existing LoadMaster to LoadMaster 360, you must first ensure the Application Programming Interface (API) is enabled on the LoadMaster (Certificates & Security > Remote Access > Enable API Interface) so that LoadMaster 360 can successfully communicate with it.

Note: LoadMaster basic authentication is not supported with LoadMaster 360. Ensure that Require Basic Authentication is disabled in Certificates & Security > Admin WUI Access. If basic authentication is enabled on the LoadMaster, LoadMaster 360 will not be able to communicate with the LoadMaster.

You can add existing LoadMasters in your network to LoadMaster 360 by following these steps:

  1. In LoadMaster 360, go to Infrastructure > Device Inventory.
  2. Click Add Device and select LoadMaster.
  3. Click Add existing LoadMaster.
  4. Select the relevant Connector and click Next.
  5. Enter a name for the LoadMaster.
    Note: The only accepted characters for the LoadMaster name field are alphanumeric characters, dashes, underscores, and spaces.
  6. Enter the IPv4 address of the LoadMaster.
    Note: Enter either the local interface IP address or the NAT-translated IP address for your LoadMaster.
  7. You can optionally specify a Port.
    Note: If you do not specify a port number, the default of port 443 is assumed. If you are adding a LoadMaster that is deployed in Azure to LoadMaster 360, ensure to specify the port number, for example, 8443.
    Note: If you are adding a High Availability (HA) pair - specify the shared IPv4 address (there is no need to add each LoadMaster individually).
  8. Enter the LoadMaster admin username.
    Note: The only accepted characters for the Admin user field are alphanumeric characters and =~^._+#,@/-.
    Note: The default administrator user on all LoadMasters is bal.
  9. Enter the Password for the administrator user specified.
    Note: The password must be at least 8 characters long.
  10. Use the Schedule enabled toggle to enable or disable backup scheduling for this LoadMaster.
  11. If backup scheduling is enabled, select either Every day or Custom schedule (for example, weekdays only), and set the backup execution time.
  12. Click Next.
  13. A number of setting changes are required on the LoadMaster to ensure it can communicate successfully with LoadMaster 360. You can click the changes link to review what changes will be made. Select the I agree to make the following changes to the LoadMaster check box to proceed with the addition.
    Note: Do not undo these changes on the LoadMasters you want to manage through LoadMaster 360. Do not perform the following acts:
    • Remove the Connector from the list of syslog hosts (IP address)
      • Change the port or settings in the Syslog Options (UDP on port 514 is required)
    • Remove the local LoadMaster 360 user (for example, lm360_7e72f82b)
    • Remove the API key/password/client certificate generated by LoadMaster 360
    • Remove or disable the Web Application Firewall (WAF) rule for log sampling (lm-traffic-sampling.conf)
    • Undo any of the Prerequisites.
  14. Review that the information is correct and click Finish.

The LoadMaster initially displays a Status of Unknown in LoadMaster 360. Within five minutes (at most) the status of the LoadMaster should change to Healthy (if the connection was successful and the LoadMaster is in a healthy state).
