CLI Operational Mode Top-Level Commands

 

In operational mode, you enter commands to monitor and diagnose the software, network connectivity, and the router. When you log in to the router and the CLI starts, you are at the top level of the CLI operational mode. At this level, there are several broad groups of CLI commands. Table 1 lists the top-level CLI operational mode commands and describes the options available for each command. The commands are listed in alphabetical order.
