1.5.2 Using the IFCONFIG command Using the IFCONFIG command, you can display the TCP/IP configuration, and temporarily change the configuration without restarting the TCP/IP user.

Changes made to the TCP/IP configuration using the IFCONFIG command may be altered by subsequent OBEYFILE commands or when TCP/IP is restarted. For details on the IFCONFIG command, see z/VM: TCP/IP Planning and Customization, SC24-6019. To display the status of all configured network interfaces, execute the IFCONFIG command from the TCPMAINT user as shown in Figure 1-26.
