As part of Sistas SDN Projects, (www.sistas.com.tr) , we start configuring brand new Alcatel OS6868 switch. Now usb console is sufficient, just be sure that USB to UART driver is installed properly. In my case it is not

sdn OS6860 - uart driver problem

Fix is easy, download necessary controller driver from Silicon Labs site http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx.

Now lets try opening a terminal. Here I will use Tera Term http://download.cnet.com/Tera-Term/3055-20432_4-75766675.html?tag=pdl-redir.

Just serial communication port that we obtained above.

Default password of a brand new switch be admin / password.

Now let’s try to setup connection to controller. Our controller is placed on, let’s check connection using an old friend called “ping”. If it fails with complaining about “network is unreachable” assign a valid ip, or let dhcp supply one (if the system is not isolated) in order to use for management. This process may be seen at the figure below;

Arp table of switch should be populated to include our controller ip as may be seen below;

Now we may try to set controller settings for OpenFlow southbound API.

Start with creating a logical switch. Start with default parameters;

Then bind a controller to logical switch just created;

At this point we see that there is no traffic request for controller. Actually, the problem is we should assign a vlan other than default to logical switch. Let’s assign a vlan, and check state again. see that state will change to Active.

We should see traffic between switch to controller,

OpenDaylight controller should also see the OS6860,
