Configuring TCP/IP when the operating system is in restricted state

If you need to configure TCP/IP while the operating system is in restricted state, perform the steps outlined in this topic. You can use both IPv4 and IPv6 addresses for your system.

As a network administrator, you might encounter some situations that you must prevent users from changing any configuration. This requires that your operating system must be in restricted state. To configure TCP/IP in restricted state, you must first start TCP/IP using special parameters, and then start a specific IPv4 or IPv6 interface to allow access to the system.

The following restrictions apply when the operating system is running in restricted state:

You can only start interfaces that are not attached to a network server description (NWSD).
You cannot start TCP/IP servers (the STRTCPSVR command), because they require active subsystems.

Complete the following tasks to configure TCP/IP while your operating system is in restricted state:
