An NVMe/TCP port is a logical interface that connects a SVM to a physical TCP capable device. This table collects diagnostics and performance information for an NVMe/TCP 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_tcp_port:port and nvmf_tcp_port:node are nvmf_tcp_port_port and nvmf_tcp_port_node respectively.

Classic Object: nvmf_tcp_port

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.

Properties
