Switch Setup

Physically accessing the switch

I am running Ubuntu 14.04 on a laptop that has USB ports. I also have putty SSH client installed. Most of our switches are old and still use the Serial port connection for direct access. We can still use that but we need a USB to female Serial port cable. I plugged a USB-to-Serial cable to my laptop and check the last entries in dmesg:

polkaron@Ubentu:~$ dmesg | tail
[79465.042532] usb 2-1.1: new full-speed USB device number 5 using ehci-pci
[79465.135955] usb 2-1.1: New USB device found, idVendor=067b, idProduct=2303
[79465.135964] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[79465.135970] usb 2-1.1: Product: USB-Serial Controller D
[79465.135974] usb 2-1.1: Manufacturer: Prolific Technology Inc. 
[79465.136479] pl2303 2-1.1:1.0: pl2303 converter detected
[79465.138104] usb 2-1.1: pl2303 converter now attached to ttyUSB0

Note the above output. The most important entry is the last line that mentions "ttyUSB0"

You must open Putty SSH Client as root. Upon opening Putty, I scroll all the way down to the Serial submenu. There is a line called "Serial Line to connect to" In this space is where I want to write in the name that dmesg showed when I plugged in my USB-Serial connection so I'll write "ttyUSB0" into the space (which is probably prepopulated with some other weird entry).

Afterwards on Putty, I'll scroll back to the top of the menu and click "Session". On "Connection Type", I want to select "Serial" and on the Serial Line, I want to enter the same dmesg title for the connection "ttyUSB0"
