3 Command Modes for the NX-OS CLI
Cisco's NX-OS CLI is a great tool for automating NX-OS-equipped devices. As a best practice, the NX-OS CLI breaks down commands into three different modes. Each mode is designed to work with a specific set of commands, though each mode also has access to the larger set of commands as well. Those three modes are the EXEC Command Mode, Global Configuration Command Mode, and the Interface Configuration Command Mode.
When launching the NX-OS CLI users are automatically placed in the EXEC command mode. This mode includes commands such as show and clear. In this mode, commands are run to execute some kind of action that does not save a configuration.
The Global command mode offers the widest range of commands. In this mode, commands issued affect the device globally. Configurations can be saved in this mode.
Finally, the Interface configuration mode is what is used to configure specific interfaces on a device. Commands issued in this mode need to address one specific interface only, and as such, only affect that interface and not the device globally.
