This topic explains the steps to configure the Controller Cluster IP.

To configure the Controller cluster IP:

Procedure

  1. Navigate to Administration > Controller > Nodes > Edit.
  2. Specify the name of the cluster in the Name field.
  3. Specify either the Controller Cluster IPv4 address or the Controller Cluster IPv6 address. The IP address entered will be dynamically reconfigured to the IP of the cluster Leader.

  4. To form a Controller Cluster of three Controller nodes, you should add additional two nodes to the cluster. Click ADD to add cluster nodes. In the ADD CLUSTER NODE screen, ensure that all cluster nodes are added using one of the following methods:

    • SelectIP Address and enter either the IPv4 or the IPv6 Address of the node.

    • Select FQDN and enter the v4 IP address of the Controller virtual machine.

      Note:

      The FQDN option is valid only to create IPv4 Controller cluster.

  5. Enter the Hostname and Password.
  6. Enter the Public IP Address which is valid only for v4 cluster. IPv6 address is not supported for public address.

  7. Click Save.

Results

The Controller Cluster IP gets programmed as a sub-interface on the leader node's primary NIC, and must be in the same subnet as the controller nodes. Whenever there is a failover, this IP is reprogrammed on the new leader's primary NIC.

Example

10.146.3.2 is the Controller cluster IP programmed on a leader in a three-node cluster.
