Subnet mask
Defines which part of an Internet address forms the subnet (subnetwork) field of an Internet address. An example of a
Line description
Contains information describing a communications line that is attached to the iSeries server, as defined previously in “Step
To find the names of the currently defined line descriptions, use the Work with Line Descriptions (WRKLIND) command.
Associated local interface
Allows the network to which this interface is attached appear to be part of the same network that the associated local interface is attached to. This is referred to as transparent subnetting.
Transparent subnetting allows TCP/IP traffic to flow between the two physical networks without defining additional routing. This is only valid for
Automatic start
Refers to whether the TCP/IP interface is started automatically whenever TCP/IP is started. The default setting is *YES. If you choose *NO, you must start the interface yourself by using the STRTCPIFC command or by selecting option 9 (Start) on the Work with TCP/IP Interfaces display, as shown in Figure 4 on page 12.
To add a TCP/IP interface, do the following:
1.Enter GO TCPADM to get the TCP/IP Administration menu.
2.Select option 1 to get to the Configure TCP/IP menu.
3.Select option 1 on the Configure TCP/IP menu.
The Work with TCP/IP Interfaces display is shown in Figure 4 on page 12.
4.Type option 1 (Add) at the
(You can go directly to this display by typing ADDTCPIFC command on any command line and pressing F4.)
iSeries TCP/IP supports multihoming, which allows you to specify multiple interfaces for each line description. See “Multihoming Function” on page 56 for further information.
