Connect your Cisco Switch / Router on Ubuntu

Requirements for Configure a Cisco device from Console port:

A Host machine with your preferred O.S. In this case I’m using an Ubuntu 12.04 LTS.

A serial port in your computer motherboard or a USB to RS232(Serial) Converter.

A text based terminal emulation (i use minicom in this example)

Its also useful to install a TFTP server on your machine if you want to copy file from or to your Cisco switch / Router. I choose to use the tftpd-hpa

Check for active Serial ports on Linux:

Before we proceed we need to check all the available Serial ports on your machine and write down the port name because we will need it for configuring minicom. Open a terminal and type :

dmesg |grep tty

output:

In my case i have a pl2303 USB to Serial Converter and the name of this device is “ttyUSB0”
