The process of designating a device for central management by BIG-IQ Web Application Security is known as discovery.

Once a BIG-IP device is discovered, all security policies and virtual servers on the device come under management by the BIG-IQ system.

For each device discovered, the system creates an extra virtual server to hold all policies not related to any virtual server in the discovered device.

After discovery, BIG-IQ Web Application Security enables a view of devices and properties, policies, and virtual servers associated with those devices and a way to perform device-specific and policy-specific actions.

To view all devices managed by BIG-IQ Web Application Security, navigate to the Devices panel.

1. To begin the discovery process, navigate to the Devices panel. At first login, this panel is empty because there are no discovered devices.
2. Hover over the Devices header and click the + icon to display the property fields for a new device.
3. Edit the property fields as required.

   Option	Description
   Device Address	Enter the internal self IP for the BIG-IP device. Note: Each managed device must be configured with a communication route from its internal self IP or management IP address to a BIG-IQ system internal self IP address on a configured BIG-IP VLAN. Otherwise, discovery will fail. F5 recommends that you use a self IP address (on the BIG-IP device) in order to gain access to additional functionality that is not provided through the management port.
   User Name	Enter the user's login name. For example: admin.
   Password	Enter the password for this user.
   Auto Update Framework	Select this check box to force an update of the REST framework on the BIG-IP device. Certain BIG-IQ system components should be installed and kept up-to-date on all BIG-IP devices brought under central management. These components provide a REST framework that supports the required Java-based management services.
   Check box	Clear this check box (the default setting) to ensure that the discovery process does not overwrite the source of imported policies already on the BIG-IQ system.

4. Click Add.

1. Navigate to the Devices panel.
2. Hover over the banner of the device you want to monitor and when the gear icon appears, click it to expand the panel.
3. In the expanded panel, view health data under device properties.

1. To display properties for an individual device, hover over the header for that device (in the Devices panel).
2. Click the gear icon to display and expand the panel containing device properties.

Once configurations are in sync between BIG-IP devices and the BIG-IQ Web Application Security system, there is seldom a need to rediscover a BIG-IP device.

However, some scenarios that might require rediscovery include:

• Additions, deletions, or changes made to self IPs or virtual servers on the BIG-IP device.
• Changes to security policies made locally on the BIG-IP device.
• Updates made to the BIG-IP device's software that need to be recognized by BIG-IQ Web Application Security.

If any of these scenarios occur, you must rediscover to reconcile any changes with the configuration maintained on BIG-IQ Web Application Security. If you do not reconcile changes, a subsequent deployment process will overwrite any changes made locally.

The rediscovery process is modal. This means that once rediscovery starts, the process blocks you from performing any other tasks or interacting with BIG-IQ Web Application Security in any way until the process completes or is canceled.

1. To begin the removal process, navigate to the Devices panel.
2. Hover in the Devices header and click the gear icon to display the expanded Properties panel.
3. In the expanded Properties panel, click Remove.
