SDN Out-of-Band Configuration

17 Mar 2026

This guide is for the OT Software Defined Networking (OT-SDN) solution. It comprises of a OT-SDN Controller and OpenFlow compatible switches. 

APPLICABLE PRODUCTS 

OT-SDN Controller HW (for example: ABD4003-SDN-CTRL)

OT-SDN Controller License Subscription (ABD-SDN-LIC-1Y-1)

    Software Version 3.3.1-20260218.1

OT-SDN Switches (for example: ABD-SDN-SW-60208 or ABD-SDN-SW-60216)

    Firmware Version E20251027

PRE-REQUISITES

In an Out-of-Band configuration the switches are connected to each-other through an unmanaged switch and the management traffic (OpenFlow) between the Controller and the switches is passed through the unmanaged switch. 

SDN

SSH into the switch using either the Console port (COM) or using regular ethernet (IP), the default IP is printed on the side.

If you use COM make sure you have the right COM number, you can find it in “Device Manager” under Ports (COM & LPT) COM9 is correct in this case.

Here is how it would look like using PuTTY.

Once the console has appeared you will be asked to login.

Commands

SDN Out-of-Band

Enable
Conf t
ip address 192.168.200.20 255.255.255.0 #IP you want the switch to have
openflow controller ip 192.168.200.2 #IP of the SDN controllers ethernet port
openflow controller port 6653
openflow store-flow
openflow enable
copy run start
reboot

Other commands

erase startup-config #Clears all saved settings and return the switch to factory default

SDN Controller

Configure OT-SDN Controller

Login to Controller

Connect to the OT-SDN Controller GUI by opening a browser and surfing to https://<ip-of-ethernet-1>/ 

Default IP: 192.168.200.10
Username: admin
Password: ???

Configure Ethernet Ports

Navigate to Configurations -> Controller.

Here you can change the default IP and activate the other ethernet port.

It is recommended to activate the other ethernet port in order to have access to the Web GUI, as one port need to be connected to the switches

Learning Mode

Top right you will see “Mode” and under that “Operational” click it and more options will appear, click “Learning Mode”, a new window pops up, click “Enable” and the Controller will now be in “Learning Mode”

The Controller will now automatically add rules depending on the traffic in the SDN network.

To see the automatically added rules, on the left press “Policies” -> Rules (Top left).

Under the policy column you will see "Learned Rules", these are are the rules that has been added by "Learning Mode"

Add Traffic Rules manually

On the left press “Policies” -> Rules (Top left) then +Add Rule (Top right), in the new window you will see this:

Policy: Where you want the rule to be
Directive: What you want the rule to do
Protocol: What protocol the rule should affect
Source: What the source is, this could be Any, Zone, the device or the type
Destination: What the source is, same options as above
Bottom field: Describes what the rule does
