An NVMe/FC LIF is a logical interface that connects an SVM to a NVMe/FC capable physical port. This table collects diagnostics and performance information for an NVMF LIF. The table counters can be used to debug and diagnose connectivity issues with initiators or fabric on a LIF. The table counters can be used to debug and diagnose connectivity issues with initiators or fabric at a LIF level granularity. The alias names for nvmf_lif:node and nvmf_lif:port are nvmf_lif_node and nvmf_lif_port respectively.

{instance_name}:{instance_uuid}

(not applicable)

This represents the construction of the row ID field, which is a single unique string that identifies a row.

constituent

This represents the construction of a row ID field for a row from a single node.

{port_id}:{port_wwpn}

port

This represents the construction of the row ID field in port combo object, which is a single unique string that identifies a row.

{node.name}:{node.uuid}

node

This represents the construction of the row ID field in node combo object, which is a single unique string that identifies a row.
