Study Notes
Cisco Packet Tracer
- Platform for network simulation
-
IOS (Internetwork Operating System):
- Multitasking operating system used in most Cisco routers and switches
- Has a Command-Line Interface (CLI) with predetermined commands
- Network Equipment Dependency: All network equipment depends on the operating system.
Shell
- User interface, used to request specific tasks from the computer
- Tasks are performed through CLI (Command Line Interface) or GUI (Graphical User Interface)
- Manages communication between hardware and software.
- Manages hardware resources to meet software requirements
Kernel
- Manages communication between hardware and software
- Manages hardware resources
Hardware
- Physical components of a computer.
-
Memory Types:
- ROM (Read Only Memory): Cannot be altered, responsible for booting.
- RAM (Random Access Memory): Running configuration; loses content when restarting.
- Flash Memory: Stores IOS images, other files.
- NVRAM (Non-Volatile Random Access Memory): Stores startup configuration files and retains content on restart.
Common Accesses on IOS
-
Console Access:
- Used to configure newly acquired devices
- Does not require an IP address
- Cannot be accessed through a network
-
Telnet Access:
- A common way to access a network device remotely
- Uses a terminal emulation program
- Allows for remote configuration of IOS devices.
-
SSH (Secured Shell):
- Remote access similar to Telnet
- Uses public-key cryptography for security
Connect Devices
-
Device LEDs:
- Indicate device status
- Examples like Cisco 1941 LEDs provide status information
IOS Access Methods
- Console: Direct connection for configuration
- Auxiliary: Another connection method for configuration
- Virtual Terminal: Telnet/SSH for remote access
- Terminal Emulation Programs: Software to connect to devices remotely (e.g., PuTTY, Tera Term).
- Secure CRT: A specific terminal emulation program for remote access.
