This document details 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 virtual IP address in the Controller Cluster IP field.
  3. Under Cluster Nodes, enter the Node IP, Hostname, Password, and the Public IP Address or hostname of the Controller virtual machine.

    The Edit Controller Configuration screen appears.

    Note:

    In case of an existing two-node or three-node cluster configuration, to change the Controller cluster IP from the cluster IP configuration screen, delete the existing cluster IP and add a new one.

  4. Starting with NSX Advanced Load Balancer 22.1.3, the following UI is available:
    1. Navigate to Administration > Controller > Nodes.
    2. Click Edit. The EDIT CLUSTER screen is displayed.

    3. Under Cluster Node, click ADD to add the Node IP, Hostname, Password and Public IP Address.

    1. 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.
