Steps: - 1. Visit the official website of Netacad using any web browser. 2. Press the login button and select log In option. 3. Next screen will appear, click on the sign - up option. 2 4. Next screen will appear and will ask for email and password and other simple details, fill them and click on Register. 5. Now the login screen appears again so fill in the Email id. 6. O n the next screen enter the password and press the Login button. 3 7. Dashboard will initialize, now click on Resources and choose Download Packet Tracer Option. 8. On the next web page choose the operating system to download the packet tracer. Downloading will start automatically. 9. Check for the executable file in your system and run it. 4 10. Next screen is of License Agreement so Click on I accept the license. 11. Choose the installing location which has sufficient space. 12. Select the start menu folder and click the Next button. 5 13. Check the box for creating a desktop icon and click on the Next button. 14. Now packet tracer is ready to install so click on the Install button. 15. The installation process will start and will hardly take a minute. 6 16. Click on the Finish button to complete the installation. 17. An icon is created on the desktop so run it. 18. Interface is initialized and the software is ready to use. 7 Interface Overview When you open Packet Tracer, by default you will be presented with the following interface: This initial interface contains ten components. If you are unsure of what a particular interface item does, move your mouse over the item and a help balloon will explain the item. 1 Menu Bar This bar provides the File, Edit, Options, View, Tools, Extensions, Window and Help menus. You will find basic commands such as Open, Save, Save as Pkz, Print, and Settings and Preferences in these menus. You will also be able to access the Activity Wizard from the Extensions menu. Window menu 8 allows to enter/exit full screen mode, lists all top level windows open by Packet Tracer and allows to activate them. 2 Main Tool Bar This bar provides shortcut ico ns to most commonly used menu commands. This bar provides access to these commonly used workspace tools 3 Common Tools Bar Logical/Physical Select, Inspect, Delete, Resize Shape, Place Note, Drawing Palette, Add Simple PDU, and Add Complex PDU. See "Wor kspace Basics" for more information. 4 Workspace and Navigation Bar You can toggle between the Physical Workspace and the Logical Workspace with the tabs on this bar. In Logical Workspace, this bar also allows you to go back to a previous level in a cluster, create a New Cluster, Move Object, Set Tiled Background, and Viewport. In Physical Workspace, this bar allows you to navigate through physical locations, create a New City, create a New Building, create a New Closet, Move Object, apply a Grid to the background, Set Background, and go to the Working Closet. 5 Workspace This area is where you will create your network, watch simulations, and view many kinds of information and statistics. You can toggle between Realtime Mode and Simulation Mode with the tabs on this bar. This bar also provides buttons to Power Cycle 6 Realti me/Simulation Bar Devices and Fast Forward Time as well as the Play Control buttons and the Event List toggle button in Simulation Mode. Also, it contains a clock that displays the relative Time in Realtime Mode and Simulation Mode. 7 Network Component Box This box is where you choose devices and connections to put into the workspace. It contains the Device - Type Selection Box and the Device - Specific Selection Box. There's a searchable field that allows you to enter a device name t o look for that specific device quickly. Device name shows when you mouse over the device icon in the Device - Specific Box 8 Device - Type Selection Box This box contains the type of devices and connections available in Packet Tracer. The Device - Specific Selection Box will change depending on which type of device you choose. 9 Device - Specific Selection Box This box is where you choose specifically which devices you want to put in your network and which connections to make. In this box, you'll find de vices that may have already been obsolete. You have an option to hide legacy equipment in the Preferences window under Options. 10 User Created Packet Window* 9 This window manages the packets you put in the network during simulation scenarios. See the "Simulation Mode" section for more details. * You can completely hide the User Created Packet Window (UCPW) by clicking on the expand/collapse button. You can also freely resize UCPW by placing the cursor near the left edge of the window (it will turn into a "resize" cursor) and then dragging the cursor left or right. Workspaces and Modes Packet Tracer has two workspaces (Logical and Physical) and two modes (Realtime and Simulation). Upon startup, you are in the Logical Workspace in Realtime Mode. You can build your network and see it run in real time in this configuration. You can switch to Simulation Mode to run controlled networking scenarios. You can also switch to the Physical Workspace to arrange the physical aspects (such as the location) of your devices. Connecting Two devices 10 Connecting Devices using switch Connecting Devices using switch 11 LAB - 2 Switch & Telnet 1. Change Host name to Chaitanya. 12 2. Configure Telnet on Chaitanya. Step - 1 Set password to switch to protect from unauthorized access. 13 Step - 2 Now configure Telnet 14 Accessing Telnet Remotely 15 3. Connect Server to Chaitanya and assign IP address 192.168.1.1 to Server 16 4. Need to have 3 department Sales, Marketing and HR each department should have 3 PC in each, assign IP address to all PC and All department should communicate with each other and they should access Server. Code: en config t hostname Chaitanya1 exit sh vlan brief show run config t interface vlan 1 ip address 192.168.1.1 255.255.255.0 no shutdown 17 exit exit config t line vty 0 4 password cisco login exit enable secret 123 exit To check wether telnet is it working or not telnet 192.168.1.1 en LAB - 3 18 VLAN Configuration Create a topology consisting 2 switches each having 3 vlan each vlan should have 2 PC in each, assign IP address to all PC. Identify switchports of interest and assign VLAN numbers. Identify and configure trunk port between switches (if needed) Steps: 1. Draw topology 2. Assign ip address to pcs 3. Create VLAN on switch and name them accordingly 4. Identify switchports of interest and assign VLAN numbers. 5. Identify and configure trunk port between switches (if needed) Switch - 1
