All rights reserved.ICND v2.01-35Summary (Cont.)The Cisco router uses Cisco IOS software with extensive command-line input help facilities, including context-sensitive help.
51、The Cisco IOS CLI includes an enhanced editing mode that provides a set of editing key functions. The Cisco router CLI provides a history or record of commands you have entered. This feature, called the command history, is particularly useful to help you recall long or complex commands or entries. After logging in to a Cisco router, you can verify the router initial startup status using the router status commands: show version, show running-configuration, and show startup-configuration.
