CLI Operational Mode

In operational mode you enter commands to monitor and troubleshoot the software, network connectivity, and the router by entering commands. 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 (see Table 19).
