Operating Cisco IOS Software
Objectives
Upon completing this lesson, you will be able to:
Set up console connections between Cisco network devices and a terminal, given a need to configure and monitor network equipment
Describe the features of the Cisco IOS user interface

Cisco IOS Software Features
Configuring Network Devices
Configuration sets up the device with the following:
Network policy of the functions required
Protocol addressing and parameter settings
Options for administration and management
Catalyst switch memory has initial configuration with default settings
Cisco router will prompt for initial configuration if there is no configuration in memory
An Overview of Cisco Device Startup
Configurations can come from many sources.
Configurations will act in device memory.
External Configuration Sources
A CLI is used to enter commands.
Operations vary on different internetworking devices.
Users type or paste entries in the console command modes.
Enter key instructs device to parse and execute the command.
Two primary EXEC modes are user mode and privileged mode.
Command modes have distinctive prompts.
Cisco IOS User Interface Functions
There are two main EXEC modes for entering commands.
Cisco IOS Software EXEC Mode
Cisco IOS Software EXEC Mode (Cont.)
Summary
The Cisco IOS software platform is implemented on all Cisco hardware platforms.
You will use Cisco IOS software to communicate the configuration details that implement the learning objectives of this course.
You can configure a switch or router from sources that are external to the device.
Cisco IOS software uses a CLI as its traditional console environment. While Cisco IOS software is a core technology, Cisco IOS software operation details vary on different internetworking devices.
The Cisco IOS software supports two EXEC command modes: user and privileged.
