This PCbased product simulates a wide variety of Cisco routers as well as the Catalyst , , and switches.
The exercises in this lab guide only require the NetSim — they do not require access to any external router or switch hardware. It should be noted that the NetSim supports many, but not all of the IOS commands available on a real router or switch. All the commands referenced in this lab guide are supported through the Simulator. You will be presented with a screen that has buttons at the top representing each router, switch, or PC that you will be configuring.
Press one of the buttons to configure a device. There is also a button that can be pressed to show the network topology that the labs are based on. Lab Topology The Lab Topology is shown in the diagram on the next page it can also be viewed by selecting the Topology button at the top of the NetSim screen.
Specific interface IP addresses are included in a table on page 6. Lab Scenarios There are 20 labs contained in this Lab Guide. These labs build upon each other so the best approach is to follow the labs sequentially.
You will also be asked questions at various points during the lab. Answers to these questions are contained in Appendix B at the back of this lab guide. Appendix C also contains the completed configurations for selected labs. You will then be prompted for a file name. Each individual device configuration must be saved separately.
At a minimum, you should plan to save all configurations each time you power off your PC. The configuration will then be loaded. Note: this process can take seconds to complete and you will see configuration commands flash across the screen. Be patient! Copyright c Boson Software, Inc. In this lab, you will get practice with basic configuration and show commands on the Cisco router.
Select Router1 from the tool bar. Type enable to get into privileged mode. The pound sign indicates you are now in privileged mode. Notice that there are more commands available in privileged mode than are available in user mode. Configure and reload are two such commands that can only be issued in privileged mode. Exit privileged mode by typing disable.
Notice how the prompt changes. Router config hostname router1 router1 config 9. In global configuration mode on router1, type enable?. This will show valid parameters that can be entered with the enable command. Question: when both encrypted and unencrypted enable passwords are configured, which one is used? Configure an IP address for the Ethernet0 interface on router1 refer to the table on page 6 for all IP addresses and masks. You should see a message that the interface has now come up.
Practice using the tab key — type int and then the tab key no spaces. You should see the word interface spelled out. Practice using abbreviated commands for both interface serial0 and no shutdown. Exit configuration mode by keying ctrl-z. This will bring you back to the privileged mode prompt. You could also accomplish the same thing by keying exit twice. The exit command moves you back one level from interface-configuration mode - global configuration mode - privileged mode prompt.
Type logout to exit the command line interface router1 logout Press the enter key to get back into the user mode prompt and then type enable to get into privileged mode. Display a summary of all interfaces by typing: router1 show ip interface brief Display detailed information on each interface by typing: router1 show interfaces Display the active configuration in DRAM by typing: router1 show running-config If not, why not?
Save the running active configuration to NVRAM by typing: router1 copy running-config startup-config Issue the show version command and answer these questions: a. Question: What IOS release is running on router1? Question: What are the contents of the configuration register? Issue the command to show which Layer 3 protocols are currently running on the router. Question: which protocols are currently running on the router? Select router2 from the toolbar on top.
Press enter and get into user mode. From there go into privileged mode. Router config hostname router2 router2 config enable secret cisco Display the summary status of all interfaces. Remember to get out of configuration mode first before issuing any show commands. Question: Were you successful? If not, what commands should you use for troubleshooting?
In this lab you will practice using some advanced configuration and show commands on the Cisco router. Please remember your lab 1 commands needed to switch between Router modes i. The console user must enter this password before gaining access to the user mode prompt.
Test the banner and console password by logging out of the router and logging back in. Get into enable mode after successfully logging into the console. Display the contents of flash memory on router2. Question: what is the name of the IOS image in flash and how large is it? Display the history table on router1. This shows the last 10 commands that were entered on the router. On router1, do a show interfaces on Serial 0. Note on the third line of the output that the bandwidth is assumed to be kb.
This description will appear whenever you issue a show interfaces command for Serial 0. In this lab, you will practice using Cisco Discovery Protocol CDP commands to view information about directly connected neighbors.
You should see one-line entries for both router2 and router3. On router1, display detailed information about CDP neighbors. On router1, display the interfaces where CDP is active. Question: what is the CDP advertisement interval? Question: what is the holdtime interval and what does it signify? On router1, change the CDP advertisement interval to 50 sec. Issue the show cdp interface command to verify the new timers are set correctly.
You will suspend Telnet sessions using the ctrl-shift-6 X sequence and display active Telnet sessions using the show sessions and show users commands. From router1, Telnet to router2 Once into router2, issue the show users command. You should return to router1 without breaking the active Telnet session. Issue the show sessions command on router1. This command shows what active, but suspended, sessions you have to other routers.
Now Telnet from router1 to router3. Suspend the session and return to router1. Issue the show sessions command. You should now see two suspended sessions: one to router2 Disconnect the two suspended sessions on router1. The number used in the disconnect command comes from the left-most column in the show sessions output.
Issue show sessions to see if the suspended Telnet sessions have disappeared. Configure PC1 to have an IP address of Use the winipcfg utility on the PC to do this.
On router4, make sure you can ping PC1: router4 ping On router4, copy your running-configuration to the tftp-server. You will be prompted for the address of the tftp-server You will also be prompted for a file name any name you choose. If it is not empty, use the erase startup-config command to clear it.
Issue the show startup-config command. In this lab, you will be configuring RIP. On router1, issue the show ip protocols command. This commands shows information about all dynamic routing protocols that are running on the router. Based on the output of this command: a. Question: how frequently does RIP advertise routing updates? Network Simulator features more than lab exercises, with support for hundreds of Cisco IOS commands.
Model ChemLab - Evaluation Version 2. It has been originated from academics to computer simulation. Model ChemLab consists of a real-time animated interactive simulation engine.
It features lab wizard tools which can be used to create lab simulations. The simulation so made can be replayed using the demonstration mode. DSS is defined in many different ways depending upon the speaker or author. We define DSS as tools, processes, and methods for rehearsing the future.
This is a term coined by Dr. Peter Keen, the founder of the DSS movement. VERALAB is a computer lab management system, which addresses day-to-day activities in a computer lab at university, college, school, training center, or library. These include user sign-in and waitlisting, access control, surveillance, maintenance, supervision, employee attendance tracking, reporting, software metering, and license management.
