aCLI

The Acropolis CLI (aCLI) is the CLI for managing the Acropolis and AHV portion of the Nutanix product for tasks like AHV host, network, and VM management. These capabilities were enabled in releases after AOS 4.1.2 and are available on Nutanix AHV cluster CVMs only. aCLI is not supported on Prism Central.

The current aCLI command reference can be found on the Nutanix Portal.
