SDN Controller HP 3800 Openflow switch discovery

I have an HP 3800 openflow switch and cannot discover the switch in the HP SDN Controller (2.3.5)

The controller is in network network of VLAN 6 (Port 1), which is not the Openflow instance VLAN 10, as required.

I can see in tcpdump TCP session for port 6633 SYN request from the switch (10.1.10.191 on VLAN 6) to the controller 10.1.10.10, and seeing the TCP RST and so no tcp session established for the switch<->controller. I assume that is the reason my OF Switch not discoverd by the controller.

 

I check iptables, and there is tcp port 6633 ACCEPT, also i flushed iptables just in case.

Is there something in the SDN Controller to start discovering and listening to the openflow switches ?

Is by default the SDN Controller will listen to port 6633 from OFswitch 3800.

 

Attached is my configuration and outputs

Hello,

 

Since the controller is sending the RST right away when the switch is trying to connect, this does appear to be the issue.

 

Are you able to connect a mininet instance to the controller?

 

 

can you run the following commands on the controller:

 

sudo netstat -ap > netstat.out

service sdnc status

 

and then please attach the output to the case.

 

Do you have a wireshark/tcpdump capture of the 3800 trying to connect?

 

Regards,

 

Scott

Hello anzstar,

 

 

Doing a follow up to check if you get any chance to run the command as Scott had asked for.

If yes please do help us with the response of the command as well as the other details as asked in earlier post to take this further.

 

Please also let know if you have already resolved the issue

 

Thanks
