This document provides an overview of the features and content covered in Module 2: Basic Switch and End Device Configuration. The module objectives are to implement initial settings including passwords, IP addressing, and default gateway parameters on a network switch and end devices. The module covers topics such as Cisco IOS access, IOS navigation, the command structure, basic device configuration, saving configurations, ports and addresses, configuring IP addressing, and verifying connectivity. Interactive features like animations, videos, quizzes and labs are included to help learners understand the concepts.
Operating Systems
Shell - The user interface that allows users to request specific tasks from the computer. These requests can be made either through the CLI or GUI interfaces.
Kernel - Communicates between the hardware and software of a computer and manages how hardware resources are used to meet software requirements.
Hardware - The physical part of a computer including underlying electronics.
Cisco IOS Access
GUI
A GUI allows the user to interact with the system using an environment of graphical icons, menus, and windows.
A GUI is more user-friendly and requires less knowledge of the underlying command structure that controls the system.
Examples of these are: Windows, macOS, Linux KDE, Apple iOS, and Android.
GUIs can fail, crash, or simply not operate as specified. For these reasons, network devices are typically accessed through a CLI.
PC operating system enables a user to do the following:
Use a mouse to make selections and run programs
Enter text and text-based commands
CLI-based network operating system enables a network technician to do the following:
Use a keyboard to run CLI-based network programs
Use a keyboard to enter text and text-based commands
View output on a monitor
Console – A physical management port used to access a device in order to provide maintenance, such as performing the initial configurations.
Secure Shell (SSH) – Establishes a secure remote CLI connection to a device, through a virtual interface, over a network. (Note: This is the recommended method for remotely connecting to a device.)
Telnet – Establishes an insecure remote CLI connection to a device over the network. (Note: User authentication, passwords, and commands are sent over the network in plaintext.)
