Creating a virtual interface
You can use the Create VIF wizard to create a virtual interface (vif), a feature that implements link aggregation on your storage system. Vifs provide a mechanism to group together multiple network interfaces (links) into one logical interface (aggregate). The physical interface must be down before you can add a vif.
Steps 
1.
From the Home tab, double-click the appropriate storage system to display a subtree of management features.
2.
Click Configuration > Network > Interfaces.
3.
Click Create VIF to start the Create VIF wizard.
4.
Type or select information as requested by the wizard.
5.
Verify that the vif that you created is included in the list of interfaces in the Interfaces window.
