Step 6: Creating a preferred interface list

You can now create a preferred interface list to control which adapters and IP addresses are the preferred interface for virtual Ethernet proxy Address Resolution Protocol (ARP) agent selection.

Creating a preferred interface list using IBM® Navigator for i

To create a preferred interface list by using IBM Navigator for i, follow these steps:
  1. In IBM Navigator for i, expand IBM i Management > Network > TCP/IP Configuration > IPv4.
  2. Select IPv4 Interfaces to see a list of interfaces displayed in the right pane.
  3. In the interfaces list, right-click the virtual Ethernet interface for which you want to create the preferred interface list, and then click Properties.
  4. Click the Advanced tab, and complete the following steps:
    1. Select the Preferred interfaces option in the ARP Proxy drop-down list.
    2. Select the interface addresses from the Available interfaces list, and click Add.

      You can also remove an interface from the Preferred interface list in the right pane by clicking Remove, or move an interface up and down in the list to change the order by clicking Move up and Move down.

    3. Click OK to save the preferred interface list that you have created.

Creating a preferred interface list using the character-based interface

To create a preferred interface list by using the character-based interface, follow these steps:

  1. On the command line, type CHGTCPIFC (Change TCP/IP Interface command) and press F4 (Prompt) to access the Change TCP/IP Interface menu.
  2. At the Internet address prompt, specify the virtual Ethernet IPv4 interface for which you want to create the preferred interface list, and then press Enter to see a list of optional parameters.
  3. At the Preferred interfaces prompt, type a plus sign (+) by + for more values, and then press Enter.
  4. Specify up to 10 preferred IPv4 interfaces in order of preference. The first interface is the most preferred.
  5. Press Enter twice.
Notes:
  1. Only 10 interfaces are supported for the preferred interface list. If you configure more than 10, the list is truncated to the first 10.
  2. The interface for which you want to create the preferred interface list must be inactive for the list to be configured. Interfaces listed in the preferred interface list do not need to be inactive at the time the list is configured.
