Creating Ethernet line descriptions on systems other than models 270 and 8xx

 

Use these steps to create an Ethernet line description on models other than 270 and 8xx so that the system can use virtual Ethernet.

To configure new Ethernet line descriptions to support virtual Ethernet, follow these steps:

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

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

    The Ethernet ports identified as 268C are the virtual Ethernet resources. There is one for each virtual Ethernet adapter. Each port identified as 268C has an associated location code that is created when you create the virtual Ethernet adapter using the HMC (Step 1).

  3. From the Display Resource Detail panel, scroll down to find the 268C resource that is associated to the specific location code created for this virtual Ethernet.

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

  5. From the Work with Configuration Descriptions panel, select Option 1 (Create), and then press Enter to see the Create Line Description Ethernet (CRTLINETH) panel.
    1. At the Line description prompt, type VETH0. If you use the same names for the line descriptions and their associated virtual Ethernet, such as VETH0, you can easily keep track of your virtual Ethernet configurations.
    2. At the Line speed prompt, type 1G.
    3. At the Duplex prompt, type *FULL, and then press Enter.
    4. At the Maximum frame size prompt, type 8996, and then 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 then select Option 1 (Vary on) for VETH0.

  7. Repeat steps 1 through 6, but perform the steps from the command line on partition B to create an Ethernet line description for partition B.

    Although the names of the 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.
