You can set the combination of static and DHCP, IPv4 and IPv6 addresses, edit the DNS settings, and define the proxy settings for vCenter Server.

Prerequisites

  • To change the IP address of the appliance, verify that the system name of the appliance is an FQDN. The system name is used as a primary network identifier. If you set an IP address as a system name during the deployment of the appliance, you can later change the PNID to an FQDN.
    Note: You can set only IPv4 IP address as system name. The IPv4 IP address must be enabled before this setting.
  • To restore a dual stack VC, the base VC after stage 1 deployment should be configured as:
    • If PNID of backed up VC resolves to IPv4 and IPv4 is configured static, the base VC during stage1 should have static or DHCP IPv4 configured.
    • If PNID of backed up VC resolves to IPv4 and IPv4 is configured DHCP, the base VC during stage1 should have DHCP IPv4 configured.
    • If PNID of backed up VC resolves to IPv6 and IPv6 is configured static, the base VC during stage1 should have static or DHCP IPv6 configured.
    • If PNID of backed up VC resolves to IPv6 and IPv6 is configured DHCP, the base VC during stage1 should have DHCP IPv6 configured.

  • Log in to the vCenter Server Management Interface as root.

Procedure

  1. In the vCenter Server Management Interface, click Networking.
  2. From the Network Settings page, click Edit.
  3. Expand the Hostname and DNS section to configure the DNS settings.
    Note: Valid value for Hostname is either FQDN resolving to enabled IP address or IPv4 IP address.
    Option Description
    Obtain DNS settings automatically Obtains the DNS settings automatically from the network.
    Enter DNS settings manually Lets you set the DNS address settings manually. If you select this option, you must provide the following information:
    • The IP address of the preferred DNS server.
    • (Optional) The IP address of the alternate DNS server.
  4. From the Network Settings page, click Edit.
  5. Expand the NIC 0 section to configure the gateway settings.
    Note: PNID and network APIs support only NIC 0 as primary NIC.
    Recommended steps to configure network other than NIC 0, when vCenter has multiple NICs configured are:
    • NIC 1 is reserved for VCHA and should not be used in multi-NIC configurations.
    • As mentioned in the UI specifications, DGW should be set to NIC 0.
    • As access to vSphere Client is redirected to PNID, only access to NIC 0 is supported or recommended even in multi-NIC configurations.
  6. Edit the IPv4 address settings.
    Option Description
    Enable or Disable IPv4 settings Enables or Disables the IPv4 address based on the toggle switch option.
    Obtain IPv4 settings automatically Obtains the IPv4 address for the appliance automatically from the network.
    Enter IPv4 settings manually Uses an IPv4 address that you set manually. You must enter the IP address, subnet prefix length, and the default gateway.
    Note: For static IPv4 or IPv6 addresses, DNS server must be set manually.
    Note: Second and third party solutions need to re-register, when there is a change in the IPv4 and IPv6 IP addressess.
  7. Edit the IPv6 address settings.
    Option Description
    Enable or Disable IPv6 settings Enables or disables the IPv6 address based on the toggle switch option.
    Obtain IPv6 settings automatically through DHCP Assigns IPv6 addresses to the appliance automatically from the network by using DHCP.
    Obtain IPv6 settings automatically through router advertisement Assigns IPv6 addresses to the appliance automatically from the network by using router advertisement.
    Use static IPv6 addresses Uses static IPv6 addresses that you set up manually.
    1. Click the checkbox.
    2. Enter the IPv6 address and the subnet prefix length.
    3. Click Add to enter additional IPv6 addresses.
    4. Click Save.
    Note: For static IPv4 or IPv6 addresses, DNS server must be set manually.

    You can configure the appliance to obtain the IPv6 settings automatically through both DHCP and router advertisement. You can assign static a IPv6 address at the same time.

    Note: Second and third party solutions need to re-register, when there is a change in the IPv4 and IPv6 IP adressess.
  8. To configure a proxy server, in the Proxy Settings section, click Edit.
  9. Select the proxy setting to enable
    Option Description
    HTTPS Enable to configure the HTTPS proxy settings.
    FTP Enable to configure the FTP proxy settings.
    Note: Ensure that the ICMP is enabled on the proxy server.
    HTTP Enable to configure the HTTP proxy settings.
  10. Enter the server hostname or IP address.
  11. Enter the port.
  12. Enter the username (optional).
  13. Enter the password (optional).
  14. Click Save.
