[BLUE TEAM] [Network] 4.Mastering Cisco CLI Modes and Basic Configuration
This document explains the basic operation and main connection modes of the **Cisco IOS Command Line Interface (CLI)**. Users will learn the differences between User EXEC mode, which allows for basic queries, Privileged EXEC mode, which allows for detailed configuration viewing and management, and Global Configuration mode, which allows for actual device configuration changes. It also covers essential commands, such as enable secret, which sets and encrypts passwords for security, and how to save and load configuration settings. From a physical connection perspective, it distinguishes between the use of rollover cables, which are required for console port access, and crossover cables, which are used for general Ethernet connections. Finally, it is designed to review key practical concepts, such as the importance of case sensitivity when entering full command phrases and passwords, through a quiz format.
