Have you summarized the basic commands for Cisco routers?

Router command basics-mode conversion command

User Mode ---- privileged mode, use the command "enable"

Privileged mode-global configuration mode. Run the "config t" command"

Global configuration mode ---- interface mode, using the command "interface + interface Type + interface number"

Global configuration mode-line control mode. Use the command "line + Interface Type + interface number"

Note:

User Mode: view the initialization information.

Privileged mode: view all information, debug, and save configuration information

Global mode: configure all information and all interfaces for the entire vro or vswitch

Interface Mode: configuration of an interface

Line Control Mode: interface configuration for router Control
