UCSM's command line is different from Cisco's regular IOS and even NX-OS (Nexus is the base platform of FIs that runs UCSM). The UCSM CLI provides the same tab completion options as IOS and NX-OS. You can either SSH to log in remotely, or log in locally through the console access to the FI to get access to the UCS CLI.
Each UCS component can be configured using the GUI or CLI commands. Each GUI tab, and each component present in the infrastructure and represented in the GUI, has an equivalent CLI configuration command. You can navigate through various UCS components using the scope command.
Once connected to the CLI, it is also possible to connect the other advanced CLIs to individual components introduced later in the chapter.
