> | Lab 3.2.1 Router user interface - Overview Estimated time: 60 min. Objectives: Login to a router in both user and privileged modes. Use several basic router commands to determine how the router is configured. Become familiar with the router HELP facility. Use the command history and editing features. Logout of router. Background: This lab will introduce the Cisco Internetwork Operating System (IOS) command line user interface. You will login to the router and use different levels of access to enter commands in "User Mode" and "Privileged Mode". You will become familiar with the commands available in each mode (User or Privileged) and use the router HELP facility, history and editing features. The IOS command interface is the most common method of configuring a Cisco router. You will see many commands available, especially in privileged mode. Do not be overwhelmed. As with many things, the 80/20 rule applies. You can do 80% of what you need to do on a daily basis with 20% of the commands available. Tools / Preparation: Prior to starting this lab you will need to connect a PC workstation (with the HyperTerminal program loaded) to a router using the router's console interface with a roll-over (console) cable. All lab work is done through the Hyperterminal program that is configured to connect to the router. You may want to review Chapter 12 in the Cisco Networking Academy First-Year Companion Guide and review Semester 1 on-line chapter 3 prior to starting this lab. You will need to be familiar with these commands: ? enable logout show ? show running-config exit Resources Required: PC with monitor, keyboard, mouse, and power cords, etc. Windows operating system (Win 95, 98, NT or 2000) installed on PC. HyperTerminal PE program configured for router console access. PC connected to the router console port with a roll-over cable.
