Creating a VNIC Without a VLAN ID for Clustered Controllers (BUI)

This example is for an active-active configuration with half of the network ports on standby. This task creates an IP interface over a device datalink and assigns it to a head. A VNIC is built on top of the same datalink, and an IP interface is configured on top of the VNIC and assigned to the other head. Configuring one instead of multiple VNICs over a given datalink ensures peak performance. Traffic flows over the cable associated with the underlying active port on one head, as well as the underlying standby port on the other head. Thus, the otherwise idle standby port can be used with VNICs.

1. Go to Configuration > Network > Configuration.
2. When the cluster is in state AKCS_CLUSTERED, click the Datalinks add item icon .
3. Optionally, set a name and MTU value.
4. Choose a device from the Devices list and click APPLY.

   The datalink appears in the Datalinks list.

5. Click the Interface add item .
6. Set desired properties, choose the datalink previously created, and click APPLY.

   The interface appears in the Interfaces list.

7. Click the Datalinks add item icon .
8. Select the VNIC checkbox, optionally set name and MTU (equal to or less than the value in step 2), and click APPLY.

   The new VNIC datalink appears in the Datalinks list.

9. Click the Interface add item icon .
10. Set desired properties, choose the VNIC datalink previously created, and click APPLY.

    The interface appears in the Interfaces list.

11. The running appliance network configuration has not yet changed. When you are finished configuring interfaces, click APPLY at the top to commit the configuration.
12. Click the Cluster tab.

    The two newly created interfaces appear in the Resource section with default owners.

13. Use the Owner pull-down list to assign one of the two interfaces to the other head and click APPLY.
