What is a LIF?
  • A LIF (Logical InterFace) is a logical resource tied to a Vserver
    • A NAS LIF has an IP address
    • A SAN LIF has a WWPN
  • A LIF is hosted by a physical network port on a node

This separation of the physical port and the LIF allows a NAS LIF to migrate non-disruptively to another physical port on node within the cluster.
