Study Notes

Router Setup and User Interface

If no TFTP server is found, the setup dialog (setup mode) is initiated.
Setup mode is not intended to be used to enter complex protocol features in a router, but to permit administrators to install a basic configuration for routers.
Default answers appear in square brackets [ ] following the question in setup mode.
Pressing the Enter key uses these defaults.
Ctrl-C can be pressed at any time to terminate the setup process, which administratively shuts down all interfaces.

Router User Interface Modes

User EXEC mode: typical tasks include commands that check the status of a router.
Privileged EXEC mode: typical tasks include commands that change the router configuration.
Type "enable" to enter privileged mode.
Type "disable" to exit privileged mode.
Type "exit" or "end" or press Ctrl-Z to return to privileged mode from configuration mode.

Router CLI

The CLI (Command Line Interface) environment can be accessed several ways:
- Through a console session.
- Through an AUX port with a modem.
- To Telnet to the router.
Ways 1 and 2 do not require the router to have any IP services configured.
Way 3 requires at least one interface to be configured with an IP address.

Cisco IOS Software

The Cisco IOS is the embedded software architecture in all of the Cisco routers and is also the OS of the Catalyst switches.
One of the main considerations when selecting a new IOS image is compatibility with the router flash and RAM memory.
The newer the release and the more features it provides, the more flash and RAM memory it requires.
Use "show version" to check the current image and available flash.

Operation of Cisco IOS Software

The Cisco IOS devices have three distinct operating environments or modes:
- ROM Monitor mode: performs the bootstrap process and provides low-level functionality and diagnostics.
- Boot ROM mode: only a limited subset of the Cisco IOS feature set is available, and it allows write operations to flash memory.
- Cisco IOS mode: the normal operation of most Cisco routers requires a copy of the IOS to be loaded into RAM and executed from RAM.

Router Internal Components

RAM: stores routing tables, holds ARP cache, and provides temporary memory for the configuration file.
NVRAM (Non-Volatile RAM): provides storage for the startup configuration file and retains content when a router is powered down or restarted.
Flash: holds the IOS image and retains content when a router is powered down or restarted.
ROM: maintains instructions for power-on self-test (POST) diagnostics and stores the bootstrap program and basic operating system software.

Router Connections

Console port: provides physical access for initial configuration.
Management port: connects to a computer for configuration.
WAN connections: connects routers to a WAN for packet entry and exit.
LAN connections: connects routers to a LAN for packet entry and exit.

Power-On Self-Test (POST)

When a Cisco router powers up, it performs a power-on self-test (POST) to verify the basic operation of the CPU, memory, and network interface ports.
After the POST, the generic bootstrap loader in ROM executes.
A bootstrap is a simple set of instructions that tests hardware and initializes the IOS for operation.

Boot Process

The IOS can be found in several places.
The boot field of the configuration register determines the location that is used to load the IOS.
When the IOS is loaded and operational, the configuration file saved in NVRAM is loaded into main memory and executed one line at a time.
If no valid configuration file exists in NVRAM, the operating system searches for an available TFTP server.
