Configure a network adapter

As a system administrator, you can modify the network adapter settings, such as IP Mode and type, address, gateway, and MTU by using the management interface of the VMware Cloud Director Availability appliance.

Note: Applying any network changes can lead to temporary network outages. For example, the browser connectivity to the management interface is interrupted when being accessed through the network adapter that was just reconfigured.

Prerequisites

Verify that VMware Cloud Director Availability is successfully deployed.

Procedure

1. Log in to the management interface of the VMware Cloud Director Availability appliance.
   1. In a Web browser, go to https://Appliance-IP-Address/ui/admin.
   2. Under Appliance login, enter the root user password.
   3. Click Login.
2. In the left pane under Configuration, click Settings.
3. Under Appliance settings, expand the Network section.
   You can see all the network adapters that are added to the appliance.
4. Next to the adapter name click Edit.
5. In the Settings window, configure the network settings and click Apply.
   1. To select an IP mode, click IPv4, IPv6, or Unconfigured.

      By selecting Unconfigured, you turn off the adapter and delete all its settings, including static routes. Use this cleanup procedure, in case there are configuration leftovers that are causing unexpected network behavior.

   2. Click Type and select how to provide the network configuration.

      Option	Description
      DHCP	If you select DHCP to provide the network configuration, all manually configured network settings, such as DNS servers, search domains, static routes, and MTU size are removed.
      SLAAC	If you select SLAAC to provide the network configuration, all manually configured network settings, such as DNS servers, search domains, static routes, and MTU size are removed.
      Static	Enter the static configuration. In the Address/Prefix text box, enter a CIDR address - IP address, followed by a forward slash and a network mask or a prefix length. In the Gateway text box, enter a gateway that is in the same network as the provided IP address. For each IP mode, you can use only one default gateway. If you are configuring a second adapter in the same IP mode, you must not enter a default gateway. In the MTU (bytes) text box, enter the maximum transmission unit size in bytes. The default is 1500 bytes.

   The selected network adapter of the VMware Cloud Director Availability appliance is configured with the provided settings.

What to do next

• You can configure the DNS, the appliance host name, and the Domain Search Path. For more information, see Configure the network settings of the appliance.

• You can add additional network adapters to configure. For more information, see Add an additional network adapter.

• You can use the local domain as a top-level domain in VMware Cloud Director Availability appliances. For more information, see VMware KB 79088.
