Warning: VMware Enterprise PKS v1.6 is no longer supported because it has reached the End of General Support (EOGS) phase as defined by the Support Lifecycle Policy. To stay up to date with the latest software and security updates, upgrade to a supported version.

This topic describes how to configure a Virtual IP address (VIP) for the NSX-T Management Cluster for VMware Enterprise PKS.

Prerequisites

Make sure you have completed all preceding NSX-T installation tasks.

About the NSX Management Cluster VIP

The NSX-T Management Cluster comprises three NSX-T Manager nodes. To support a single access point for the NSX Manager web interface and API, assign a virtual IP address (VIP) to the NSX-T Management Cluster. Once the VIP is assigned, any UI and API requests to NSX-T are redirected to the VIP address, which is owned by the leader node. The leader node then routes the request to the other cluster nodes.

Using a VIP makes the NSX Management Cluster highly available. If you need to scale, you can provision a load balancer for the NSX-T Management Cluster. Provisioning a load balancer requires that NSX-T be fully installed and configured. It is recommended that you configure the VIP now, then if needed, install a load balancer after NSX-T is installed and configured. For more information about configuring a load balancer for the NSX-T Management Cluster, see Provisioning a Load Balancer for the NSX-T Management Cluster.

Configure a VIP Address for the NSX-T Management Cluster

Complete the following instructions to create a VIP for the NSX Management Cluster. The IP address you use for the VIP must be part of the same subnet as the NSX-T Management nodes.

  1. From your browser, log in with admin privileges to NSX Manager at https://NSX-MANAGER-IP-ADDRESS.

  2. Go to System > Overview.

  3. Click Edit next to the Virtual IP field.

  4. Enter a VIP for the cluster, such as 172.16.11.81. Ensure that the VIP is part of the same subnet as the other NSX Management nodes.

  5. Click Save.

  6. When prompted, click Refresh. In the Virtual IP field, you should see the VIP address in use as well as the NSX Manager leader node that the VIP is associated with.

After the VIP is configured, you use it to connect to the NSX-T Manager. The VIP is associated with a single NSX-T Manager. If that node goes down, the VIP attaches to another node. If necessary, you can still connect to any NSX-T manager directly using its own IP address.

Verify the VIP Address

To verify the VIP and troubleshoot issues, complete the following steps:

  1. From your browser, log in with admin privileges to the NSX-T Management Cluster using the VIP address https://NSX-MANAGER-VIP-ADDRESS.

  2. To check the API leader of the management cluster, enter the get cluster status verbose command in the NSX Manager CLI.

  3. To troubleshoot VIP issues, verify the following logs:

    • Reverse Proxy logs at /var/log/proxy/reverse-proxy.log
    • Cluster manager logs at /var/log/cbm/cbm.log
