Basic Switch and End Device Config. Flashcards
Cisco IOS Access
Interacting with a Cisco IOS device’s operating system for configuration purposes.
IOS Navigation
Moving through different command modes of the Cisco IOS to configure network devices.
The Command Structure
Hierarchical arrangement of commands in the Cisco IOS software, organized into different command modes.
Basic Device Configuration
Setting up initial configurations on a Cisco IOS device using the Command-Line Interface (CLI).
Save Configurations
Using IOS commands to save the running configuration of a Cisco IOS device to non-volatile memory.
Ports and Addresses
How devices communicate across network media using port numbers and IP addresses.
Configure IP Addressing
Assigning an IP address to a host device on a network.
Verify Connectivity
Checking the ability of two end devices to establish a connection and communicate.
GUI (Graphical User Interface)
User-friendly interface using graphical icons, menus, and windows to interact with a system.
Purpose of an OS
Functions of an operating system for users to interact and for network technicians to manage network devices.
Access Methods
Ways to remotely connect to a network device, including Console, Secure Shell (SSH), and Telnet.
Terminal Emulation Programs
Software to connect to network devices through console ports or SSH/Telnet connections.
Primary Command Modes
Modes in the Cisco IOS—User EXEC Mode for basic monitoring, Privileged EXEC Mode for all commands.
Configuration Mode and Subconfiguration Modes
Modes for configuration—Global Configuration Mode, Line Configuration Mode, Interface Configuration Mode.
Navigation Between IOS Modes
Moving between different command modes in the Cisco IOS, e.g., Privileged EXEC Mode and Global Configuration Mode.
Navigation Between IOS Modes (Cont.)
Continuing moving between modes, including Subconfiguration Modes and returning to higher-level modes.
Operating System (OS)
The software that controls and manages hardware resources of a computer system or network device.
CLI (Command Line Interface)
A text-based interface used for interacting with an operating system or software by typing commands.
GUI (Graphical User Interface)
An interface that allows users to interact with software and devices using graphical elements like icons and menus.
Console
A physical port on a networking device used for local management and configuration.
Shell
The user interface of an operating system that provides access to its services and functionalities.
Kernel
The core part of an operating system that manages memory, CPU, and other hardware resources.
Hardware
Physical components of a computer or networking device, such as processors, memory, and interfaces.
Secure Shell (SSH)
A cryptographic network protocol used to securely access and manage network devices remotely.
Telnet
A network protocol used for remote access to network devices, but it’s less secure compared to SSH.
Terminal Emulation Programs
Software that enables a computer to emulate a physical terminal, allowing remote access to devices using text-based commands.
User EXEC Mode
A command mode in Cisco IOS that provides basic monitoring commands to users.
Privileged EXEC Mode
A command mode in Cisco IOS that allows access to all commands and configurations.
Global Configuration Mode
A Cisco IOS mode for configuring general device settings.
Interface Configuration Mode
A Cisco IOS mode for configuring specific interface settings.
Enable Secret
A command used to set a password for privileged EXEC mode, which is more secure than the “enable” password.
VTY Line
A virtual terminal line that enables remote access to network devices via Telnet or SSH.
Command Syntax
The structure and rules that define how commands should be written and used in a command-line interface.
Argument
A value or variable provided by the user as part of a command in a command-line interface.
Banner MOTD
A message displayed to users when they log in to a networking device, often used for legal notifications or warnings.
Startup-Config
A configuration file stored in non-volatile RAM (NVRAM) that is used to restore settings after a device restarts.
Running-Config
The current configuration file stored in volatile RAM, reflecting the device’s current settings.
DHCP (Dynamic Host Configuration Protocol)
A protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network.
Switch Virtual Interface (SVI)
A virtual interface on a switch that is associated with a VLAN and allows remote management using an IP address.
IPConfig
A command-line tool in Windows used to display the IP configuration settings of a network interface.
Show IP Interface Brie
A command used in Cisco IOS to display a brief summary of IP addresses assigned to interfaces.
Reload
A command used in Cisco IOS to restart a device, causing it to reload its configuration.
Erase Startup-Config
A command used in Cisco IOS to delete the startup-config file from NVRAM.
Command Shortening
Using abbreviations for commands or keywords to expedite command entry.
