So you’ve got to support some Cisco gear but all you’ve got is a Mac. The problem is that there are no serial ports and no blatantly obvious way of connecting to a console port.
Unfortunately there’s one thing you may need to purchase. You’ll need an FTDI USB to Console cable. You can pick these up on Amazon for about $15.00. You may be able to find them for cheaper on eBay.
Note: If your version of OS X is 10.8 or below then you may have to install the FTDI driver for USB to Serial cable.
Once you’ve got that you can follow the instructions below:
- Open up terminal (Macintosh HD -> Applications -> Utilities -> Terminal)
- Connect the FTDI cable to the USB port on your Mac and the other end to the console port of the Router / Switch
- Enter the following commands:
- cd /dev
- ls -ltr /dev/*usb* (If this doesn’t find anything you can try ls /dev/tty*)
- You should see a list of ports, hopefully there’s only one or two of them. What you’re looking for is the port that starts with tty.
- In my case the full path would be /dev/tty.usbmodem1a21
- You then type the following command
- screen /dev/tty.usbmodem1a21 9600
- The 9600 is for the baud rate
- To disconnect from the console you have to issue the following commands
That’s it. Happy routing…
