Changing your line description

To make changes to an existing line description, follow these steps.

   1. Type WRKLIND and press Enter.
   2. Locate your line description, and place your cursor in its Opt field.
   3. Type 8 (Work with status) and press Enter.
   4. Type 2 (Vary off) and press Enter. If your line description does not vary off, place your cursor on the error message and press F1 (Help) to view more information about the error. If you need help with the error, see Troubleshooting.
   5. Press Enter.
2. Type CHGLINETH description_name (where description_name is the line description being changed) and press F4 (Prompt).
3. Specify the correct values for the Line speed field and the Duplex field. If you are not familiar with the input/output adapter (IOA), see Hardware requirements for Ethernet.
4. Specify the serviceability option. The default value for this parameter is *NONE. If you need to specify another character value, do it under the guidance of your service provider.
5. If you are using this line description with TCP/IP, ensure that source service access point (SSAP) X'AA' and its associated information are in the SSAP list field.
6. If you want to use the larger frame sizes of Gigabit or 10 Gigabit Ethernet, ensure that all the nodes along the communications path can support the frame sizes.
7. Press Enter to save your changes.
