Troubleshooting
Problem
This document discusses how to change a TCP/IP address, or interface, on the IBM iSeries family of servers system.
Resolving The Problem
The following are steps to change a TCP/IP address on IBM OS/400 or IBM i5/OS:
|
1. | On an operating system command line, type the following: CFGTCP Press the Enter key, and select Option 1. |
| 2. | Select Option 10 to end the Interface. |
| 3. | Press F12 to get back to the Configure TCP menu. |
| 4. | Select Option 2 to work with routes. |
| 5. | If there is a route that is associated with the interface, it will need to be removed. Otherwise, you will get an error later when trying to remove the old TCP/IP address. (Press F6 to print this screen. It will go to your spooled file so you can have a record of it.) |
| 6. | Once the route is removed, press F12 to return to the configure TCP screen. |
| 7. | Select Option 1 to work with TCP interfaces. |
| 8. | Select Option 1 to add the new TCP/IP address. |
| 9. | Select Option 9 to start the new TCP/IP address. |
| 10. | Select Option 4 to remove the old TCP/IP address. |
| 11. | Press F11 and the new TCP/IP address should be in an active status. |
| 12. | Press F12 to get to the Configure TCP/IP menu. |
| 13 | Select Option 2 to work with TCP/IP routes. |
| 14. | Select Option 1 to add a route if needed. |
| 15. | Press F12 to get to the Configure TCP/IP menu. |
| 16. | Select Option 10 to work with the Host Table. If you have the old TCP/IP address associated with the Host Name of the iSeries family system, you must remove the old address, then add a Host Name with the new TCP/IP address. If you do not have anything there, then you do not have to do anything. |
| 17. | Press F12 to get to the Configure TCP/IP menu again. |
| 18. | Select Option 12 to change TCP/IP Domain. If the TCP/IP address of a Domain name server changes too, you will change it here. If you do not have an external Domain name server, then you will not need to make any changes. |
| 19. | Your PCs should now be able to connect to the new TCP/IP address on OS/400 or i5/OS. |
