Connecting to Serial Console

A USB-to-Serial adapter will be used to connect to the console port of the EdgeSwitch.

NOTE: In order to connect to the console we will need to use the following items/programs:

RJ45 to DB9 serial console cable (rollover cable)
USB to DB9 adapter
Terminal emulation program, such as PuTTY or the macOS/Linux terminal

1. Open the terminal emulator and specify the serial COM line and the baud rate/speed.

Windows Client

Enter the following information in the PuTTY window.

macOS Client

Open Terminal Application and find the serial interface ID.

ls -ltr /dev/*usb*

The serial interface will display as tty. Example output below:

ls -ltr /dev/*usb*
crw-rw-rw-  1 root  wheel   21,   3 Feb  8 15:48 /dev/cu.usbserial-AI038TPF
crw-rw-rw-  1 root  wheel   21,   2 Feb  9 08:56 /dev/tty.usbserial-AI038TPF

Use the screen command to connect to console by pasting in the path to the serial interface.

screen /dev/tty.usbserial-AI038TPF 115200

ATTENTION: Replace /dev/tty.usbserial-AI038TPF with the value given when using the ls -ltr /dev/*usb* command.

2. Connect to the EdgeSwitch and log in using your credentials.
