An FCP LIF is a logical interface that connects a SVM to a physical FCP port. This table collects diagnostics and performance information for an FCP 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 fcp_lif:svm and fcp_lif:port are fcp_lif_svm and fcp_lif_port respectively.
