Thanks, KK & Varghese. I will try that out.

Hi Chitra,
this is what I understand
(this code snippet is from the unmodified hub.cc file)
ofp_flow_mod* ofm;
size_t size = sizeof *ofm + *sizeof(ofp_action_output); *//*
#1:* make this * sizeof(ofp_action_output)
boost::shared_array raw_of(new char[size]);

Hi Chitra,
The ofp_flow_mod struct has an array of actions (i.e., struct
ofp_action_header actions[0]). So, you can append one action after
another and send a single flow_mod.
Hope I am being clear.

Warning: sending two separate flow_mod would be the wrong way.

Hi,
In most of the examples that I see, the controller sends an ofp_flow_mod
instructing the switch to take 1 action for a rule.
I am wondering how to specify 2 actions for a rule. Do we just send two
messages- 1 for each action?
Or is there some other message format to specify 2 actions for a matc
Hi Chitra,
You have to construct a ofp_flow_mod message (specified in openflow.h)
and send it to the switch. In NOX, I typically use a boost shared
array to hold the message, then it is just a send_openflow_command. I
cannot find a very clean segment of code, but you can look at
routing.cc for t
I believe the controller can specify many actions to be taken for a matching
packet.
I need a switch to send some packets to the controller and forward it to an
output port.
Can someone tell me how we can construct such rules with nox?
