Connect to the switch console

Connect the CONSOLE port of the switch to a computer of your choice. If a Linux machine is used, multiple client applications are available to connect to the switch console.

Here, we provide instructions for minicom and ckermit, assuming the switch is connected in port /dev/ttyUSB0.


The default configurations of minicom can be used to connect to the switch, with exception of the console port and hardware flow control. Running minicom in a command line with the following command will start it in setup mode (omit the -s for skip setup):

sudo minicom -s -D /dev/ttyUSB0

In Serial port setup, set hardware flow control to No by pressing F. Exit setup by pressing esc and minicom will then connect to the switch.


After installing ckermit, edit a file named .kermrc in your home folder with configurations as follows:

set line /dev/ttyUSB0
set speed 115200
set carrier-watch off
set flow-control xon/xoff

Run kermit with the following command:

kermit .kermrc

After following this page, you can continue to the ONIE installation, or if your switch already has ONIE installed then Install BISDN Linux.
