VMware vSphere 5.0 Evaluation Guide - Volume One The New esxcli Command For the first time, the new esxcli command is unified for both local and remote command-line administration. In addition, the esxcli command has been enhanced to perform many tasks previously only performed with the vicfg- commands. However, it does not yet perform all the tasks. When performing configuration tasks from the command line, the esxcli command is the preferred command. Only fall back to the vicfg- and other vCLI commands when there is no esxcli command available. Moving forward, all the vCLI commands are scheduled to be replaced by esxcli commands. NOTE: In vSphere 5.0, the esxcli command does not yet provide a full set of command capabilities. Continue to use the esxcli command in conjunction with the vicfg- and other vCLI commands (that is, vmware-cmd, vmkfstools, and vifs). The esxcli command in vSphere 5.0 is not backward compatible with earlier versions of the command, because it introduces a new syntax that is different from earlier vSphere releases. esxcli Command-Line Syntax The esxcli command is made up of a hierarchy of namespaces. At each level of the hierarchy there are additional namespaces and commands. This provides for a user-friendly CLI interface that allows for the easy discovery of the command syntax.

The New esxcli Command
For the first time, the new esxcli command is unified for both local and remote command-line administration. In
addition, the esxcli command has been enhanced to perform many tasks previously only performed with the
vicfg-
commands. However, it does not yet perform all the tasks. When performing configuration tasks from
the command line, the esxcli command is the preferred command. Only fall back to the
vicfg-
and other vCLI
commands when there is no esxcli command available. Moving forward, all the vCLI commands are scheduled to
be replaced by esxcli commands.

esxcli Command-Line Syntax
The esxcli command is made up of a hierarchy of namespaces. At each level of the hierarchy there are additional
namespaces and commands. This provides for a user-friendly CLI interface that allows for the easy discovery of
the command syntax.

esxcli Namespace Hierarchy
The preceding figure provides a graphic illustration of the command to query the ESXi firewall. The user invokes
the
esxcli
command with the
network
namespace, the
firewall
sub-namespace, and the get command.
The following is an example of this command:
