Some examples of command input and output for the router command line interface (CLI) include special formatting intended to help you understand what you are doing and seeing.

router> enable [Starts privileged mode; prompt changes from router> to router#]
router# show version
Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.3(2)T, RELEASE SOFTWARE (fc3)
[Additional lines of command output are displayed]
–More–  [Press Enter until you see the router prompt]
router#  [Stops at router prompt]

In the example of command input and output above:

• At the beginning of lines, words and characters such as “router>” and “router#” are router CLI prompts. Instead of “router”, you may see the name of the router or some other word.
• Words in boldface are router CLI commands that you enter, such as “enable” and “show version“.
• Words not in boldface are router CLI prompts and command output. The actual command output that you see may not match the examples exactly, but should be similar.
• Underlines are added to help you quickly find relevant information in lines, such as under “C800-UNIVERSALK9-M” and “Version 15.3(2)T”. These underlines do not appear in actual command output.
• Brackets [ ] enclose explanations to help you understand a line of command input or output. These explanations do not appear in actual command input or output and you should not type them into the CLI.
