This chapter provides information on managing virtual interfaces, including virtual-interface failover rules and static routes.
A virtual interface is associated with a network port and is assigned an IP address. A port can be configured with one or more virtual interfaces with IP addresses and additional failover interfaces. Each virtual interface can reference one or more physical network interfaces for failover. If one physical interface fails, a second one takes over. Virtual interfaces can also be configured with static routes, which can help network traffic move more efficiently.
Each virtual interface is associated with, at most, one virtual server to provide client access to it. See “Virtual Server Concepts” for more information.
A virtual interface in Data ONTAP 10.0 differs from a virtual interface in Data ONTAP 7G or earlier. A virtual interface or vif in Data ONTAP 7G or earlier is known as a port aggregate in Data ONTAP 10.0. See “Port Aggregates” for information about port aggregates.
