Hello, It seems that your switch probably does not support the type of the message being sent. Looking by the second byte in the error message I can see that the message is of the type OFPT_BARRIER_REQUEST.
I know that HP Pro curve switch doesn't support Barrier requests on OpenFlow 0.9. http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c03170243/c03170243.pdf But I can't ensure if it's true for the switch OpenFlow 1.0 firmware.
