Configuring Lockdown mode

Lockdown mode prevents remote personnel from logging in to the ESXi host by using the root login name. By default, lockdown mode is

disabled. If you enable lockdown mode and do not configure other local host user accounts to have standalone host access through the

vSphere Client, the root user does not have access through the vSphere API and CLI.

NOTE: When you enable the lockdown, non-VMware VIBs such as OpenManage does not work.

You can continue to access the host through the direct console or through an authorized and centralized management application, such

as vCenter Server.

1. Select Configure Lockdown Mode and press Enter.

2. Press the Spacebar to select Enable Lockdown Mode and press Enter twice.
