For existing NSX Managers with only an IPv4 address, you can configure an IPv6 address so that the NSX Manager becomes dual stack (both IPv4 and IPv6).

You can configure an IPv6 address for NSX Manager with the CLI. It is not possible to perform this task through the NSX Manager UI or by API.

Note: NSX Managers do not support an IPv6 only configuration.

After configuring NSX Manager with an IPv6 address, the communication between NSX Manager and hosts automatically switches from IPv4 to IPv6 provided that the hosts are configured with IPv6 or dual stack.

Note: For communication between dual stack NSX Managers and dual stack hosts, IPv6 is prioritized.

Prerequisites

  • Ensure that you have NSX Manager configured with an IPv4 address. See NSX Manager Installation Requirements.
  • Ensure that the IPv6 address to be used for the NSX Manager has the same hostname on the DNS server as the existing IPv4 address configured to NSX Manager.

Procedure

  1. SSH or log into the NSX CLI.
  2. Run the command set interface eth0 ipv6 <NSX Manager's IPv6 address> gateway <NSX Manager's gateway IP address> to configure the IPv6 address for the NSX Manager node.
    Example: 
    NSX Manager> set interface eth0 ipv6 2620:124:6020:1045::ad/64 gateway 2620:124:6020:1045::253

    If the IPv6 address is configured successfully, the following confirmation appears:

    IPv6 address successfully updated. Node may take some time for IPv6 migration.
Node restart is required for IPv6 functionality to work properly.
    Attention: After running the command, it may take a few minutes for the communication between the NSX Manager and hosts to switch to IPv6.
  3. Restart the NSX Manager by running the command: 
    nsx-manager> reboot
Are you sure you want to reboot (yes/no): y
  4. (Optional) Run the command get interface eth0 to verify that the IPv6 address has been configured for the NSX Manager node.
  5. Run the command set name-servers <DNS IPv6 address> to configure the IPv6 address for the DNS server.
