Cisco IOS Access and Configuration

Cisco IOS is software for managing network devices (routers, switches).
Access methods include: console port (direct connection), Telnet/SSH (remote, SSH is safer due to encryption).
Accessing the device initiates a command-line interface (CLI).

IOS Modes

User EXEC Mode: Basic checks (e.g., Switch>).
Privileged EXEC Mode: Enhanced monitoring and troubleshooting (e.g., Switch#).
Global Configuration Mode: Global configuration changes (e.g., Switch(config)#).

Command Structure

Keywords and Arguments: Specific terms and values used in commands.
Context-Sensitive Help: Using "?" displays available commands/options.
Command Completion: Tab key completes commands, shows possible matches.

Basic Device Configuration

Device Name: Unique hostname for the switch/router.
Passwords: Set for console, privileged EXEC, and remote access (e.g., SSH).
Banners: Legal warnings or messages displayed before login.

Configuration Saving

Running Configuration: Active settings in RAM, disappears on restart.
Startup Configuration: Saved in NVRAM, loads on startup.
Save the Running Configuration to Startup Configuration using: copy running-config startup-config.

Ports and Addresses

Ports: Physical (Ethernet) and logical connections (port numbers for protocols).
IP Address: Numerical label for each network device.
MAC Address: Unique address for each network interface card (NIC).

Configuring IP Addressing

IP Address and Subnet Mask: Define device address and network portion.
Default Gateway: IP address of router connecting networks.
Proper IP Addressing ensures data travels between networks.

Verifying Connectivity

ping: Tests if an IP address is reachable.
traceroute (tracert): Shows the network path to a destination.
Verifying connectivity confirms network functionality.

Test your knowledge on Cisco IOS access methods, modes, and command structures. This quiz covers important concepts such as User EXEC Mode, Privileged EXEC Mode, and Global Configuration Mode. Ensure you're familiar with basic device configuration and command usage.
