Your customer wants to know more about the network configuration within the cluster.

In ONTAP SAN concepts, aLogical Interface (LIF)represents a logical network access point used by clients, hosts, or internal cluster services to communicate with storage. A LIF is not a physical port; rather, it is an abstraction that allows ONTAP to provide network resiliency and flexibility.

A LIF can be defined as either anIP address(used for NAS, management, and intercluster traffic) or aWorld Wide Port Name (WWPN)(used for SAN protocols such as FC and FCoE). Each LIF is associated with a physical port but can fail over to other ports based on defined policies, ensuring continuous access during failures or maintenance.

Broadcast domains define Layer 2 network groupings for ports, but they do not contain pools of IP addresses. IP address pools are defined insubnets, not broadcast domains. Physical ports provide connectivity, but they do not represent LIFs themselves. Separating network domains is handled byIPspaces, not LIFs.

Therefore, the correct description of a LIF is that it isan IP address or WWPN associated with a port, making optionCcorrect.
