Objectives Use the available configuration tools to establish connectivity to the appropriate network device in order to complete the initial device configuration Verify the default configuration of each device, given a functioning access layer switch and router 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 Identify the differences between the user EXEC and privileged EXEC modes Slide 4 INTRO v1.0a8-4 2003, Cisco Systems, Inc. All rights reserved. Cisco IOS software delivers network services and enables networked applications. Cisco IOS Software Features Slide 5 INTRO v1.0a8-5 2003, Cisco Systems, Inc. All rights reserved. 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 Slide 6 INTRO v1.0a8-6 2003, Cisco Systems, Inc. All rights reserved. An Overview of Cisco Device Startup 1.Find and check device hardware. 2.Find and load Cisco IOS software image. 3.Find and apply device configurations. Slide 7 INTRO v1.0a8-7 2003, Cisco Systems, Inc. All rights reserved. Configurations can come from many sources. Configurations will act in device memory. External Configuration Sources Console Port Auxilliary Port Interfaces Virtual Terminal PC or UNIX Server Web or Network Management Server Telnet TFTP Slide 8 INTRO v1.0a8-8 2003, Cisco Systems, Inc. All rights reserved. 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 Cisco IOS Slide 9 INTRO v1.0a8-9 2003, Cisco Systems, Inc. All rights reserved. There are two main EXEC modes for entering commands. Cisco IOS Software EXEC Mode First Mode: User Mode Limited examination of switch or router Command prompt: hostname> Slide 10 INTRO v1.0a8-10 2003, Cisco Systems, Inc. All rights reserved. Cisco IOS Software EXEC Mode (Cont.) Privileged (or Enabled) Mode Detailed examination of switch and router Enables configuration and debugging Prerequisite for other configuration modes Command prompt: hostname# Second Mode (and Most Commonly Used): Slide 11 INTRO v1.0a8-11 2003, Cisco Systems, Inc. All rights reserved. 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. Slide 12
