Preferred interface list
A manual selection mechanism is added to give you control over which adapters and IP addresses will be the preferred interface for virtual Ethernet and virtual IP address (VIPA) proxy Address Resolution Protocol (ARP) agent selection. You can now create a preferred interface list to select the adapters and IP addresses for the ARP proxy agent. The preferred interface list is configurable for both virtual Ethernet and virtual IP address interfaces. To find more detailed information about this new function, see Scenario: Adapter failover using virtual IP and proxy ARP.
