The vSphere Command-Line Interface (vSphere CLI) command set allows you to run common system administration commands against ESXi systems from any machine with network access to those systems. You can also run most vSphere CLI commands against a vCenter Server system and target any ESXi system that vCenter Server system manages. vSphere CLI also includes a set of host management commands: the ESXCLI command set, vicfg- commands, and some other commands. vSphere CLI also includes DCLI commands, which allow you to manage services in the vSphere REST API and are presented by the vSphere Automation SDK interfaces.
