Creating the Ethernet line descriptions

Use this procedure to configure new Ethernet line descriptions to support virtual Ethernet.

1. At the command line on logical partition A, type WRKHDWRSC *CMN, and press Enter.

2. From the Work with Communication Resources display, select Option 7 (Display resource detail) next to the appropriate virtual Ethernet port.

   The Ethernet port identified as 268C is the virtual Ethernet resource. There will be one for each virtual Ethernet that is connected to the logical partition.

3. From the Display Resource Detail display, scroll down to find the port address.

   The port address corresponds to the virtual Ethernet you selected during the configuration of the logical partition.

4. From the Work with Communication Resources display, select Option 5 (Work with configuration descriptions) next to the appropriate virtual Ethernet port, and press Enter.

5. From the Work with Configuration Descriptions display, select Option 1 (Create), and press Enter to see the Create Line Description Ethernet (CRTLINETH) display.

   1. For the Line description prompt, type VETH0. The name VETH0, although arbitrary, corresponds to the numbered column on the Virtual Ethernet page in which you enabled the logical partitions to communicate. If you use the same names for the line descriptions and their associated virtual Ethernet, you can easily keep track of your virtual Ethernet configurations.

   2. For the Line speed prompt, type 1G.

   3. For the Duplex prompt, type *FULL, and press Enter.

   4. For the Maximum frame size prompt, type 8996, and press Enter.

      By changing the frame size to 8996, the transfer of data across the virtual Ethernet is improved.

      You will see a message stating the line description has been created.

6. Vary on the line description. Type WRKCFGSTS *LIN and select Option 1 (Vary on) for VETH0.

7. Repeat steps 1 through 6, but perform the steps from the command lines on logical partitions B, C, and D to create an Ethernet line description for each logical partition.

   Although the names of your line descriptions are arbitrary, it is helpful to use the same names for all of the line descriptions associated with the virtual Ethernet. In this scenario, all the line descriptions are named VETH0.
