Before creating and configuring vifs, you must follow certain guidelines about the type, MTU size, speed, and media of the underlying interfaces.
You can group up to 16 physical Ethernet interfaces on your storage system to obtain a vif.
If you attempt to create or add to a vif and the member interfaces have different MTU sizes, Data ONTAP automatically modifies the MTU size to be the same. To ensure that the desired MTU size is configured, you can use the ifconfig command to configure the MTU size of the vif after it is created. You need to configure the MTU size only if you are enabling jumbo frames on the interfaces.
Some switches might not support multimode link aggregation of ports configured for jumbo frames. For more information, see your switch vendor's documentation.
