Changing IPv4 interfaces

You can change the properties of the existing IPv4 interfaces using either IBM Navigator for i or the character-based interface.

Changing an IPv4 interface using IBM Navigator for i

To change an existing IPv4 interface 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. Click IPv4 Interfaces to see a list of IPv4 interfaces displayed in the right pane.
  3. Right-click the IPv4 interface that you want to change, and select Properties.
  4. In the IPv4 properties window, specify the values of the properties that you want to change.

    You can change some properties of an IPv4 interface when it is in active status.

Changing an IPv4 interface using the character-based interface

Note: To run the CHGTCPIFC command, you must have *IOSYSCFG special authority.

To change an existing IPv4 interface 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 IPv4 address of the interface that you want to change, and press Enter to see a list of optional parameters.
    Note: For DHCP client interfaces, only the interface with the IP address *IP4DHCP can be changed. Interfaces automatically created by the DHCP client support cannot be changed.
  3. Specify any of the optional parameters that you want to change, and keep the default value *SAME for any parameters that you are not changing.
  4. Ensure that you specify all the parameters correctly, and then press Enter.
