Configuring TCP/IP using the character-based interface
You can use the character-based interface to configure TCP/IP for your System i™ product if you are unable to use the EZ-Setup wizard.
For example, if you want to use iSeries™ Navigator from a PC that requires basic TCP/IP configuration before iSeries Navigator will run, then you should use the character-based interface to perform the basic configuration.
To perform the configuration steps discussed in this section, you need *IOSYSCFG special authority in your user profile. For more information about this type of authority, see the chapter on user profiles in Security Reference .
To configure TCP/IP using the character-based interface, follow these steps:
- On the command line, type GO TCPADM to display the TCP/IP Administration menu, and then press Enter.
- Specify Option 1 (Configure TCP/IP) to display the Configure TCP/IP menu (CFGTCP), and then press Enter. Use this menu to select configuration tasks. Take a few moments to review the menu before starting to configure your system.
Perform the following steps to configure TCP/IP on your system.
- Configuring a line description (Ethernet)
Use these instructions to configure TCP/IP over an Ethernet communications adapter.- Turning on IP datagram forwarding
You need to turn on IP datagram forwarding so that the packets can be forwarded among different subnets.- Configuring an interface
Now you need to configure a TCP/IP interface for your system.- Configuring a route
To reach remote networks, at least one routing entry is required.- Defining local domain and host names
After specifying the routing entries, you need to define the local domain and host names to allow communication within the network.- Defining a host table
You must define the host table to allow communication with the hosts on the network.- Starting TCP/IP
TCP/IP services are not available until you start TCP/IP.
