On an IPv4 deployment of vSphere 6.5 that consists of an installed or upgraded vCenter Server and upgraded ESXi, configure ESXi and vCenter Server for pure IPv6 management connection by enabling IPv6 on the deployed nodes and reconnecting them.

Before you begin

  • Verify that the network infrastructure provides IPv6 connectivity for the ESXi hosts, vCenter Server and external database if used.

  • Verify that the IPv6 addresses for vCenter Server, the ESXi hosts and an external database, if used, are mapped to fully qualified domain names (FQDNs) on the DNS server.

  • Verify that you have version 6.5 of vCenter Server installed or upgraded. See the vSphere Installation and Setup and vSphere Upgrade documentation.

  • Verify that all hosts are upgraded to version 6.5ESXi. See the vSphere Upgrade documentation.

Procedure

  1. In the vSphere Web Client, disconnect the hosts from vCenter Server.
  2. In the Direct Console User Interface (DCUI), configure each ESXi host as a pure IPv6 node.
    1. In the DCUI, press F2 and log in to the host.
    2. From the Configure Management Network menu, select IPv6 Configuration and press Enter.
    3. Assign an IPv6 address to the host.

    4. From the Configure Management Network menu, select IPv4 Configuration and press Enter.
    5. Select Disable IPv4 configuration for management network and press Enter.
  3. If vCenter Server uses an external database, configure the database as an IPv6 node.
  4. Configure vCenter Server as a pure IPv6 node and restart it.
  5. Disable IPv4 on the database server.
  6. In the vSphere Web Client, add the hosts to the inventory.
  7. Disable IPv4 in the network infrastructure.
