[ovs-discuss] Message payload

[Rajasekaran, Monica]

If anyone else is interested in knowing how to fetch the payload info from packetOut, create an object for ofputil_packet_out (eg:po). Use ofputil_decode_packet_out to decode the packet and use the object with attributes of structure ofputil_packet_out to get any packetOut related information.

Thanks,
Monica

Hi,

Because I convert the payload from string to bytes and send from the controller (ODL), I thought *oh = msg->data should have this byte version of my sent message string. Am I missing something else here?

I send "abcde" from the controller. I see the packet sent from ODL and when received on OVS, "printf ("%d",*oh)" gives "754978052". I even tried printing in hex which gives something else random.

Thanks

Hi,

When the openflow messages are received to ofproto/ofproto.c --> handle_openflow__(), is it possible to get the payload of the message received ? I would like to print that out and see. I can see that the function switches based on the "type" field in the message header and the header info to the corresponding handler functions. But, not sure how to get the payload.

Thanks,
Monica
