nvmf_lif

02/11/2024 Contributors

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.
