CLI Prompt
After you log in, you see the CLI prompt for the Cisco IOS XR software. This prompt identifies the
name of your router, and the CPU to which you are issuing commands. In most cases, this prompt
represents the “CPU0” in the primary RP that controls the system.
The CLI prompt represents the path, through the router, to the CPU that executes the commands you
enter. (See Figure 2-3.) The syntax for the CLI prompt is: type/rack/slot/module: router-name#. The CLI
prompt is described in Table 2-1.
