Study Notes
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.
