Hi,

I have been having trouble extracting packet information at the controller...

The packets are being forwarded to the controller OK, and I can see payload and 
some other data. However, I am unable to extract any information useful to my 
purpose.

For example, I'd like to monitor the UDP port for the packet, I can see that...

Packet.getMatch().getLayer4Match();

... looks as though it should UDP source & destination.

The issue seems to be that Packet.getMatch() always returns null.

I've been working on this for a while, and can't seem to make any progress, any 
help would be much appreciated.

The basic code I'm using is as follows:

@Override
    public void onPacketReceived(PacketReceived packetReceived){
                LOG.info("JACOB Raw packet match.... {}", 
packetReceived.getMatch());

    }
