Description
The ESXi Shell is an interactive command line environment available locally from the Direct Console User Interface (DCUI) or remotely via SSH. Activities performed from the ESXi Shell bypass vCenter role-based access control (RBAC) and audit controls. The ESXi shell must only be turned on when needed to troubleshoot/resolve problems that cannot be fixed through the vSphere client.
