Instructions

The OCC Cisco On-Line Lab is constructed to allow Cisco Academy Labs to be performed over the Internet at any time day or night. Students will connect directly to the console ports of the Cisco Routers and Switches. This allows OCC to give more students access to labs and encourages hands on training with live equipment.

Lessons Learned, Common Sense, and Common Courtesy

1. We recommend you use HyperTerminal Private Edition or PuTTy vice Windows built in Telnet client. Windows telnet has problems with displaying the “show run” command results. Other telnet capable software (procomm, Teraterm) has not been tested.
2. We recommend you download the latest editon of HyperTerminal Private Edition or PuTTy (both are free) to avoid scrollback buffer problems observed in the default Windows installation of HyperTerminal. You can get the latest version of Hyperterm Private Edition in software directory of the Occisco FTP site. You can connect to the FTP site here. You can get the latest edition of PuTTy by going to google.com and typing in "PuTTy" as the search term, follow the putty link, select the download page, and click on putty.exe to download.
3. Disconnect your session when finished. This will ensure that the next student can get in.
4. You may wish to save your HyperTerminal connection properties to your desktop by selecting File, Save As….
5. Remember that debug and status messages are directed to the console port of the router. The Lab connection is to the console port. If you telnet across your lab network you will not see the status and debug messages on the destination router but will see status and debug messages from the router you are physically connected to.
6. Use only passwords class and cisco on lab routers. This will prevent the time consuming process of password recovery for other students.
7. Don’t forget to use the no service config and no ip domain-lookup commands after you have restarted your router.
8. Don’t forget to put the clock rate command on the DCE end of your serial interfaces. You can determine the DCE end of the interface with the command show controllers entered at the privileged exec prompt.

Connecting Instructions

Students can connect to the Lab by Telnetting from any computer on the Internet or at the Camarillo Center.

Connect to the Lab at its Internet Universal Resource Locator: p1.occisco.com:<Port Number>

The <Port Number> is 2000 plus the number of the router. For example, Router 1 is port 2001. You would reach it by telnetting to ccna1.occisco.com:2001. The Lab switches, S1, S2, & S3 are on port 2006, 2007, & 2008 respectively. For example, to reach Switch 1 tel net to p1.occisco.com:2006.

Don’t forget to hit <Enter> after you are connected to see the “Router>” prompt of the lab router.

Here is a nice description of how to set up your computer to use other telnet clients (HyperTerm PE, PuTTy, etc.). The example is for HyperTerm, so for PuTTy, just include the complete path ending with putty.exe.

Note: Internet Explorer 7 (IE7) disables Telnet by default. To re-enable it, download and run this registry edit file (regedit). IE7_Telnet_enable.reg For a more detailed information, click on this Berkeley link.

Note: Windows Vista and Windows 2008 don't allow Telent to work by default. The IE7 fix only works for Windows XP & Windows 2003. To get to work, Windows Vista and Windows 2008 you need to install Microsoft's Telnet program too. After Telnet is installed, you should be able to change the telnet program to Hyperterm or PuTTy using the procedure above.

Line Clearing Instructions

If you get a message that the connection is denied, (and you know your outbound Internet ports are not being blocked) you can clear the connections to the routers and switches by telnetting to p1.occisco.com:2000, from the Internet or p1.occisco.com:23 from the classroom. After you log in you will have a router exec prompt that looks like: “Pod1>”. At this prompt, you can clear router & switch connections with the command “Pod1>clear line 1” for Router 1 or “Pod1>clear line 6” for Switch 1.
