1 ECE 4110 Internetwork Programming Lab 5: Setting up a Network Using Cisco Routers, Switched and VLAN Technology Group Number: ________ Member Names: _________________________ _________________________ Date Issued: Oct 22, 2010 Date Due: Nov 5, 2010 Last Edited: February 12, 2007 NOTICE: Because there are only three setups, each group will need to sign up for timeslots on the sheets attached to the lab door. You can only sign up for a total of 2 hours (4 slots) at a time, AND YOU MUST USE THE SAME SETUP FOR THE ENTIRE LAB. These can either be in a row or spread out, but no group can have more than 4 slots reserved at any one time. Once one of your slots has expired, you can sign up for another one. See Appendix C for instructions on how to save and reload your work if you need to leave and continue later. Please read the entire lab before you show up to start working on it. Fill this blank in after you make your reservation: We signed up for PLAYSTATION #: ________________ Lab Goals  Configure switches and routers on a network  Understand VLANs  Understand routing and sub-interfaces PART I Section I: Logging into the Routers/Switches All of the routers and switches are accessible from a Digi console CM32. There are three playstatations: playstation1 (Enterprise), playstation2 (Bad ISP/University), and playstation3 (Good ISP). From here on in, they will be referred to as playstationX, where X is the number of the playstation you are working on. The following instructions describe how to access the Digi console CM32 and log into a port which is in turn connected to the console port of the Cisco equipment: You may use any free mini-net computer with your own hard drive inserted into it to communicate with the rack of equipment. In order to connect to the CM32 you need to set up your mini-net’s machine network card to access its network: # ifconfig eth0:0 192.168.254.<100+group #> So group 1 is 192.168.254.101, and so forth. You will need to do this every time you power off your machine. What this does is set up a virtual interface, so you have two IP addresses on one network card. This allows you access to two networks with only one interface card. You will be using a series of scripts to help you set up the routers and save your work. These scripts are described in detail in Appendix C. First, go to Appendix C and install the scripts (on your hard drive) according to the directions. Once this is done, MAKE SURE NO ONE ELSE IS USING THE PLAYSTATION YOU WANT TO USE. This is very important, as you are about to reset the equipment configuration, and all of their work will be lost.2 Now that you are sure no one else is using the playstation, reset your chosen playstation by running the reset_pX script in the mnet_tools_v1.5 directory. Several windows should pop up. DO NOT CLOSE THEM UNTIL IT IS SAFE TO DO SO. If you are on playstation 1 or 2, you will get an error in one of the windows about VPN or Firewall processing not being enabled; ignore this for now. Once all of the other windows say it is safe to close them, do so. Now run the download_pX script to save the current configuration. From now on, you’ll run the download_pX script to save your work, and the upload_pX to restore the configuration of the playstation to the last saved state. Before running the upload script, MAKE SURE NO ONE ELSE IS USING THE PLAYSTATION. Once you have reset your playstation, connect to the CM32: #ssh [email protected] If it comes up, Type yes to the RSA question. password: playstationX (Note X is a number) The following screen appears: =============================================================== Port# Port Title Mode Port# Port Title Mode =============================================================== 1 Port Title #1 CS 2 Port Title #2 CS 3 Port Title #3 CS 4 Port Title #4 CS 5 Port Title #5 CS 6 Port Title #6 CS 7 Port Title #7 CS 8 Port Title #8 CS 9 Port Title #9 CS 10 Port Title #10 CS 11 Port Title #11 CS 12 Port Title #12 CS 13 Port Title #13 CS 14 Port Title #14 CS 15 Port Title #15 CS 16 Port Title #16 CS 17 Port Title #17 CS 18 Port Title #18 CS 19 Port Title #19 CS 20 Port Title #20 CS 21 Port Title #21 CS 22 Port Title #22 CS 23 Port Title #23 CS 24 Port Title #24 CS 25 Port Title #25 CS 26 Port Title #26 CS 27 Port Title #27 CS 28 Port Title #28 CS 29 Port Title #29 CS 30 Port Title #30 CS 31 Port Title #31 CS 32 Port Title #32 CS Enter command (1-32 serial port, others for exit) ------> Each router/switch has a console port connected to a port on the digiconsole. The digiconsole port numbers are what identifies each router and are printed to the left of each machine on the racks in the back of the room. Table 1.

Then, type in the number for the 3550 switch into the port selection screen. You may need to hit <ENTER> a few times to get a prompt. You are now logged into the network device at the port you specified. To log out of that device, type control-Z and then hit x. Figure 1 shows the network topology that we will be creating with the switch and routers. It shows the three physical routers (Mars, Saturn, and Earth) as well as the 6 VLANs we will be creating on the switch. Go ahead and fill in the Digi #’s for the different components. Make sure you write down the number of the playstation you are working on. (You are only filling in four blanks Digi #______ and the playstation blank at this point in the lab).
