Interfaces

You might want to verify interfaces on the server.

Verify that the appropriate IPv4 or IPv6 interfaces are configured on your server, and make sure they are active.

IPv4 interfaces

To display information about the IPv4 interfaces on your server:

  1. Type NETSTAT or WRKTCPSTS on the command line to display the Work with Network Status menu, and then select option 1 on this menu.
  2. You should have at least two active interfaces. Verify that these interfaces are active:
    • Loopback (127.0.0.1).
    • i5/OS™ IP address interface. This is the interface on your local server.
  3. If these interfaces are not active, select option 9 (Start) to start the interfaces.

You might want to check the status of other interfaces. For example, if you are trying to Ping interfaces on other hosts on the network, you should verify that those interfaces are active.

IPv6 interfaces

To display information about the IPv6 interfaces on your server:

  1. Type NETSTAT or WRKTCPSTS on the command line to display the Work with Network Status menu, and then select option 4 on this menu.
  2. You should have at least one active interface. Verify that this interface is active:
    • Loopback (::1)
  3. If this interface is not active, select option 9 (Start) to start the interface.

You might want to check the status of other interfaces. For example, if you are trying to Ping interfaces on other hosts on the network, you should verify that those interfaces are active.
