LAB 1-1 Accessing a Router using Hyperterminal & SecureCRT

Equipment you need to perform this LAB 1) A working Computer 2) Cisco Router with power cable 3) Console cable / Rollover cable 1)  A working Computer

You can see the COM ports (DB-9 connector) on the back side of CPU.

COMPORTS

2)  Cisco Router with Power Cable In this Lab, we have used Cisco 2600 series Router. The process of accessing CLI of a Cisco Device is same for all Routers and Switches.  You can see the Console Port at the back side of the Router or Switch. C2600

c2611

3)  Console Cable/ Rollover Cable The two sides of the Rollover/Console Cable have two different connectors. 1) DB-9 connector (9 pin female side of console cable) 2) RJ-45 connector (8 pin connector)

Rollover cable (also known as Cisco console cable or a Yost cable) is a cable that is often used to connect a computer terminal to a Router's console port. The cable normally comes in light blue color to help distinguish it from other types of networking cables.   The name ROLLOVER shows that the pinouts on one end are reversed from the other. It is very easy to make Rollover cable on your own.

STEP 1

Plug DB-9 connector (9 ping female side of console cable) into one of the COM ports of the CPU and plug the RJ-45 connector (8 ping connector) into console port of the Router.

STEP 2

You need to open HYPERTERMINAL Program by clicking on

Start --> Programs --> Accessories --> Communications --> HyperTerminal

In "Location Information" windows, input neccessary details and click on OK button. You may put dummy information.

In "Phone and Modem options" window, select "My Location" and click "OK" to continue.

In "Connection Description" window, type any name for the connection and click on OK button.

In the "Connect To" window, select appropriate COM port (the COM port number of the PC where you have plugged the Router's console cable) and Click "OK" to continue.

In the "COM Properties" window, Click on "Restore Defaults" button and then click "OK" to continue.

Press Enter to get access to the Router's CLI.

NOTE: You will not find this Program in Windows 7 . So You should either copy the HyperTerminal Program from windows XP or use other programs to get access to the Router. Other famous programs are TeraTerm, Putty, SecureCRT, .... You can find these programs in DOWNLAOD section.

I have been using SecureCRT for a long time. It is very handy application especially when you are teaching. We can open multiple tabs for multiple connections in a single window. In addition to this, we can access GNS3 Routers using SecureCRT.

To access a Router using SecureCRT, just follow these four steps. First of all install SecureCRT software which you can downlaod from DOWNLOAD section.
  1. Run SecureCRT
  2. Select Protocol: Serial
  3. Select the Appropriate Port i.e., COM1, COM2 ....
  4. Select Baud Rate: 9600 and Click on "Connect" button.

The router will take some moments to complete its booting process. The process can be seen in the HyperTerminal. Here is a sample ouput of CISCO 2611 Router:
