The CLI provides an industry-standard way of configuring various functions of the switch. This page provides a list of supported commands, with a general description of the command, its arguments, and caveats.
SONiC may also be configured and administered via a REST API and a gRPC network management interface (gNMI) using YANG data models. Supported data models are explained in the YANG Object Reference.
This section explains sub-commands that are used to display the status of various parameters pertaining to the physical state of the network node.
