Starting a specific TCP/IP interface

You must start a specific IPv4 or IPv6 interface whichever is needed for your sockets-enabled application.

After you start TCP/IP in restricted state, you can manually configure IPv4 and IPv6 interfaces, or perform an IPv6 stateless address autoconfiguration in a normal way. Alternatively, you can use existing IPv4 or IPv6 interfaces that you have configured before.
Complete the following steps to start a specific IPv4 or IPv6 interface:
  1. Verify that the interface you want to start either specifies a virtual IP address, or uses a line description of *ELAN.
    1. On the command line, type CFGTCP (Configure TCP/IP command) and then press F4 (Prompt) to access the Configure TCP/IP menu.
    2. Specify Option 1 (Work with TCP/IP interfaces) and then press Enter.
    3. Verify the Line Description and the Line Type columns:
      • For the IPv4 interface that you want to start, verify that the Line Description column is *VIRTUALIP, or that the Line Type column is *ELAN.
      • For the IPv6 interface that you want to start, verify that the Line Description column is *VIRTUALIP, or that the Line Type column is *ELAN.
  2. Verify that the interface you want to start is not attached to an NWSD.
    1. On the command line, type DSPLIND (Display Line Description command) and press F4 (Prompt) to access the Display Line Description menu.
    2. At the Line description prompt, specify the line name of the interface and then press Enter.
    3. On the Display Line Description menu, verify that the Resource name is not *NWSD.
    If the interface is attached to an NWSD, it is recommended that you select a different interface.
  3. Start the interface.
    1. On the command line, type STRTCPIFC (Start TCP/IP Interface command) and press F4 (Prompt) to access the Start TCP/IP Interface menu.
    2. At the Internet address prompt, type the IPv4 or IPv6 address of the interface, and then press Enter.
      Note: Verify that the *AUTOSTART is not specified for Internet address.
