1.2.1-Explain the purpose of the Cisco IOS
Cisco calls its operating system the Cisco Internetwork Operating System or Cisco IOS.
It is the embedded software architecture in all of the Cisco
routers and is also the operating system of the Catalyst switches
Cisco IOS provides the following network services
◦ Basic routing and switching functions
◦ Reliable and secure access to networked resources
◦ Network scalability
Purpose of OS
Using a GUI enables a user to
◦ Use a mouse to make selections and run programs
◦ Enter text and text-based commands
Using a CLI on a Cisco IOS switch or router enables a network technician to
◦ Use a keyboard to run CLI-based network programs
◦ Use a keyboard to run CLI-based network programs
There are many distinct variations of Cisco IOS
◦ IOS for switches, routers, and other Cisco networking devices
IOS numbered versions for a given Cisco networking devices
1.2.2-Explain how to access a Cisco IOS
device for configuration purposes.
Access Methods
◦ Console port
◦ Secure Shell (SSH)
◦ Telnet
IOS Modes
user EXECmode
privileged EXECmode
global configuration mode
1.2.3 -Describe the command structure of the Cisco IOS software
The Cisco IOS command-line interface (CLI) is the primary user interface used for configuring, monitoring, and maintaining Cisco devices.
This user interface allows you to directly and simply execute Cisco IOS commands, whether using a router console or terminal, or using remote access methods.
Configuration Command Modes
modes allows the configuration of a particular part or function of the IOS device
◦ Interface mode - to configure one of the network interfaces.
◦ Line mode - to configure the console, AUX, Telnet, or SSH access
The primary configuration mode is called global configuration or simply, global config.
Navigate Between IOS Modes
Various commands are used to move in and out of command prompts
◦ To move from user EXEC mode to privileged EXEC mode, use the enable command.
◦ Use return to user EXEC mode, use the disable command.
exit / quit configuration
modes
◦ exit
◦ end
◦ ^z
Basic IOS Command Structure
• Keyword - a specific parameter defined in the operating system (in the figure, ip protocols)
• Argument - not predefined; a value or variable defined by the user (in the figure, 192.168.10.5)
IOS Command Syntax
To determine the keywords and arguments required for a command, refer to the command syntax
