About a high availability active-active cluster

You can ensure that you always have access to managed BIG-IP devices by installing two or more BIG-IQ systems in an active-active, high availability (HA) configuration. Any configuration change that occurs on one BIG-IQ system is immediately synchronized with its peer devices. If a BIG-IQ system in an active-active HA configuration fails, a peer BIG-IQ system takes over the device management.

Configuring BIG-IQ System in an active-active high availability cluster

You must activate a license on two or more BIG-IQ systems before you can configure a high availability cluster.
Configuring a high availability cluster ensures that if one BIG-IQ system goes offline, another BIG-IQ system can continue managing your devices without interruption.
  1. Log in to BIG-IQ System with your administrator user name and password.
  2. Hover over the BIG-IQ Systems banner and click the + sign when it appears.
  3. In the Peer IP Address field, type the self IP address (on the internal VLAN) of the peer system. Do not use the management IP address of the peer system.
  4. In the User name and Password fields, type the administrative user name and password for the system.
  5. From the Group list, select the group to which you want to add this BIG-IQ system.

If discovery of the newly configured BIG-IQ system fails, a Delete button displays. Verify the correct self IP address and credentials. Then click the Delete button to remove the incorrect information, and re-type the self IP address, user name, and password.
