If its only the topology, you might use vms-draw.py .xml
file. Hope this helps.

Hi all,

find where the data (such as datapathid and port) are stored and which
structure are they.

James is right, you should check with tcpdump.
By looking at the send_openflow code, you can see,
if buffer_id != None:
self.send_openflow_buffer(dp_id, buffer_id, actions, inport)
Switch the buffer_id for None and it should work, the comment is incorrect.

Have you installed a rule to send the entire packet (the type that you
want to duplicate) to the controller? If not, it may well be truncated.
So you may only be sending the truncated version out on the second dpid.
Depending on how you're checking to see if this is working, this may
just look lik
Hi Ali,
Looking at the comments for send_openflow, if buffer_id is -1 then, it
should send the packet. Though, maybe I'm still doing this incorrectly?
actions = [[openflow.OFPAT_OUTPUT, [0, 11]]]
self.send_openflow(self.dpid_of_duplication, -1, buf,
actions
Hi Aaron,
self.dpid_of_duplication is not the dpid the packet arrived on, therefore
therefore bufid is meaningless to self.dpid_of_duplication. You should send
self.dpid_of_duplication the actual packet you want to packet_out.
Hope this helps,

Hello,
When I get a specific kind of packet I want to send that packet to a
specific dpid and port and also send it to the dpid and port that the packet
was intended for.
If I do:
# send packet to end host
# note self.PortMaping[dpid, mac_to_str(packet.dst)] returns the port number
the packet.ds
Hello,
I'm looking for a way to see if adding a flow failed. In the OpenFlow
protocol, it says an ofp_error_msg message is returned. Is there any
event I can register for to catch this? I would also like to catch an
error of type OFPET_FLOW_MOD_FAILED. I'm using a python component.
Thanks!
