How to set up TCP/IP on AIX

Use commands to set up TCP/IP on most UNIX systems, such as ifconfig and route, and then make the configuration permanent by editing the initialization file. This can also be done in AIX, but it is best to use SMIT for all configurations, which will ensure that the information in the/etc/rc.net and ODM is updated.

1. Configure IP address and host name

Like other operating system support for TCP/IP, AIX first configures IP addresses and host names for communication and resource sharing between hosts. Using Smit is a convenient and reliable way to do the following: Use the Smit shortcut command:

# Smit Mktcpip

First, in the available network Interfaces screen, select the appropriate network interface. These network interfaces are recognized by the cfgmgr when the system is bootup and set to the ODM database.

Then the Minimum Configuration & Startup menu appears, at least to fill in the hostname and Internet address domains, or you can specify whether you want to start TCP now or at bootup when you are in the Start field. /IP.

Other parameters such as netmask, Name service, gateway, and cable type can also be set on this screen. If you leave network MASK domain blank, AIX provides default values based on the system's IP address class. Cabletype the meaning of optional parameters: BNC fine cable, dix thick cable, TP twisted-pair line.

The host name can also be set or modified using a private command, as follows

# smit hostname

Select Set the Hostname menu item on the Hostname screen.

Fill in the new host name in the HOSTNAME domain.

2. Routing Management

For today's LAN, the connection with the outside world is essential, so routing and routing management is also necessary.

(1) Increase routing.

To increase the routing for the host, operate as follows:

# Smit Mkroute

Fill in the destination address destination and default gateway address defaults, destination type target types can choose NET or host,metric domain defaults of 1.
