IP address and MAC address load balancing
IP address and MAC address load balancing are the methods for equalizing traffic on multimode vifs.
These load-balancing methods use a fast hashing algorithm on the source and destination addresses (IP address and MAC address). If the result of the hashing algorithm maps to an interface that is not in the UP link-state, the next active interface is used.
Note: Do not select the MAC address load-balancing method when creating vifs on a storage system that connects directly to a router. In such a setup, for every outgoing IP frame, the destination MAC address is the MAC address of the router. As a result, only one interface of the vif is used.
