Connecting to a Router/Switch

Hi All,

I have a notebook running Windows XP Pro, it does not have a serial port on the back. I have a lpt to com port converter(From Cisco) to connect to my routers console port. How do i configure SecureCRT to see the lpt port as a com port.

Thanks for your help.

You cant as far as im aware -  modern laptops come without a serial port these days which is annoying for us "Cisco-ites"
Do what I do and get a USB>Serial converter they cost pennies and work fine :)

I suspect you have a 25 pin serial to 9 pin serial converter - Serial comms used to be on a 25 pin connector as well :) Older Cisco Firewalls still have a 25 pin serial connector on them

Okay, i will get a USB>Serial converter. How do you config that then?

the converter will come with a driver that allows you to specify the com port you want it to emulate.  You will still need to set it for 9600 8 1 and none for the com port setting.

^^^^^^^^^^^^^ Correct install the driver then is just gets recognised as another com port :)

Connect your PC/Laptop to a console port.

1. A console cable kit is provided with your router/firewall in cisco equipment uss usually pale blue in colour.

The console cable kit contains:

RJ-45-to-RJ-45 console cable (blue)
RJ-45-to-DB-9 adapter (gray)

NOTE

Newer models of rollover cable come with a serial port allready moulded onto them.
Some bigger Cisco Equipment (e.g. PIX 520, 400- and 7000 series routers) need a 25 pin adaptor as well.

You can identify a rollover cable by comparing the two modular ends of the cable. Hold the cable's ends side-by-side, with the tab at the back (pointing away from you). The wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See http://www-tss.cisco.com/eservice/compass/common/common_images/rollover-cable.gif ) If your cable came from Cisco Systems, pin 1 is white on one connector, and pin 8 is white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

2. Locate the console port on the back of the router, Connect the console (or rollover) cable to the console port on the router,
see http://www-tss.cisco.com/eservice/compass/common/common_images/console_port_connect.gif 

3. On your PC, Click the Start button on the Windows Taskbar, and select Programs > Accessories > Communications > HyperTerminal. HyperTerminal launches and displays the Connection Description dialog box.

4. Type in a name and optionally select an Icon to represent your HyperTerminal session. Click OK. The Phone Number window appears.

5. Locate the Connect Using field near the bottom of the Phone Number window. Select "Direct to COM1" from the drop-down list to indicate that this connection is a local session (and not a dial-up session). Click OK. The COM1 Properties window appears.

6.  On the Port Settings tab, enter the following settings:

.Speed - 9600
.Data Bits - 8
.Parity - none
.Stop bits - 1
.Flow Control - none

7. Click OK to make the connection. The COM1 Properties window disappears. You should now see a blinking cursor in the HyperTerminal terminal window.

8.  From the HyperTerminal menu, select File > Save. This saves the Session for future use. The new named session appears in the HyperTerminal folder represented with an icon like the one you clicked in Step 3. (In the future, simply double-click this icon in the HyperTerminal folder to open the saved connection.)

9. Assuming you have already connected the router and laptop using a roll-over cable, you can verify that the session is active by pressing the Enter key on your laptop a couple of times. You should see the router prompt in the HyperTerminal window.
