nvmf_rdma_port

08/30/2024 Contributors

An NVMF RDMA port is a logical interface that connects a SVM to a physical RoCE-V2 capable device. This table collects diagnostics and performance information for an NVMe/RDMA port. 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_rdma_port:port and nvmf_rdma_port:node are nvmf_rdma_port_port and nvmf_rdma_port_node.

Table Row IDs

ID Format	Aggregation Type	Comment
{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.
{node.name}:{instance_name}:{instance_uuid}	constituent	This represents the construction of a row ID field for a row from a single node.
{port.id}:{port_ip_addr}	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.
