About device discovery

You use the BIG-IQ Cloud to centrally manage cloud resources for tenants. Resources can be located on F5 devices in a private cloud on devices in your local network, in a public cloud like Amazon EC2, or in a combination of both.

To provide access to cloud resources, you must make the BIG-IQ system aware of the devices on which the resources reside. You do this by discovering devices. To discover a device, you specify the IP address for the devices. Alternately, for those devices located in the Amazon EC2 public cloud space, BIG-IQ Cloud automatically detects them when BIG-IQ Cloud system connects to the Amazon EC2 cloud.

Discovering devices

After you license and perform the initial configuration for BIG-IQ Cloud, you can discover devices on which cloud resources exist. For successful device discovery, you must configure each F5 device you want to manage with a route to the BIG-IQ Cloud system. For devices located in a public Amazon EC2 cloud, you must configure BIG-IQ Cloud with DNS so it can resolve the endpoint by name.

You can discover only BIG-IP devices running version 11.3 or later. BIG-IQ™ Cloud includes both an application delivery controller (ADC) component and an enterprise management component. The ADC component includes support for cloud management and is installed by running a script from BIG-IQ Cloud.

The self-service resources that you provide for your tenants can be located on F5 devices in your local network, or in a public cloud. To provide access to a device's resources, you must make BIG-IQ Cloud aware of the device's existence through the discovery process. To discover F5 devices in your local network, you provide BIG-IQ Cloud with the device's internal self IP address. For devices located in a public cloud, you provide the device's external self IP address.

  1. Log in to the BIG-IQ system with the administrator user name and password.
  2. At the top of the screen, click Cloud.
  3. Hover on the Devices header, and click the + icon when it appears. The New Device panel opens.
  4. In the IP Address field, type the IP address of the managed device that you want to discover. For devices in your local network or an VMware vShield Manager cloud, use the device's internal self IP address. For devices located in an Amazon EC2 cloud, use the device's external self IP address. You cannot discover a BIG-IP Cloud using its management IP address.
  5. In the User Name and Password fields, type the administrator user name and password for the managed device.
  6. Click the Add button.
BIG-IQ system populates the properties of the device that you added, and displays the device information in the Devices panel.

About installing required BIG-IQ system components on managed BIG-IP systems

You must install specific components required by the BIG-IQ system on each BIG-IP device you want to manage. To install these components, you run a series commands from the command line.

Installing required BIG-IQ components on BIG-IP systems

You can perform this task only after you have licensed and installed the BIG-IQ system and at least one BIG-IP device running version 11.3 or later.
This task installs, onto your managed BIG-IP devices, a REST framework that supports the required Java-based management services. You must perform this installation task each time you discover a new device.
Important: When you run this installation script, the traffic management interface (TMM) on each BIG-IP device restarts. It is important that, before you run this script, you verify that no critical network traffic is targeted to the BIG-IP devices.
  1. Log in to the BIG-IQ system terminal as the root user.
  2. Establish SSH trust between the BIG-IQ system and the managed BIG-IP device. ssh-copy-id root@<BIG-IP Management IP Address> This step is optional. If you do not establish trust, you will be required to provide the BIG-IP system's root password multiple times.
  3. Navigate to the folder in which the files reside. cd /usr/lib/dco/packages/upd-adc
  4. Run the installation script.
    • For devices installed in an Amazon EC2 environment: ./update_bigip.sh -a admin -p <password> -i /<path_to_PEM_file> <BIG-IP Management IP Address>
    • For devices installed in any other environment: ./update_bigip.sh –a admin –p <password> <BIG-IP Management IP Address>
    Where <password> is the administrator password for the BIG-IP device.
  5. Revoke SSH trust between the BIG-IQ system and the managed BIG-IP device. ssh-keygen –R <BIG-IP Management IP address> This step is not required if you did not establish trust in step 2.
