Below is limitation of pronto 3290 switch.Counters are byte or packet, not both For flows, only packet counters or byte counters are supported, not both simultaneously. In the configuration of this release, only packet counters are supported. Applies to all platforms. Actions sequencing is not supported. For example, the action list with 4 actions: "(1) set VID to X, (2) output to port A, (3) set VID to Y, (4) output to port B" has the intention of sending the packet out on different ports with different VLANs.

On other platforms, the function can be implemented by setting to the system's untagged VLAN (untested). Cannot multicast and wildcard source port. Actions with a wildcard source port may not specify "flood" nor multicast (multiple output ports) with the expectation of source port blocking.

Thank you for your great response.Yes,handle_flow_route is existing in lavi_hostflow.cc line 34~60.
and handle_flow_route event call send_flow_list_function.My main question is "when doeshandle_flow_route eventoccur? "
I guess the answer is when there is a flow mod to the host. You can verify by doing a grep to see which component post the event.Hope this is useful.
RegardsKK
for example handle_req handling JSON event occur, when lavi receive json message from envi.

Sorry, I continue to be lost.if you want to send flows to ENVI, look at lavi_hostflow.cc line 34 to 60 for an example. Basically, a list of flow is created and the send_flow_list function is called.

Thank you for your response.1. "You need to include the header file for the definition of the event, then create the event, populate it and post it."
-Basically, there is part of flow_route_event in lavi_hostflow.cc. so I don't have to include the header file, right ?.register_handlerFlow_route_event (boost::bind(lavi_hostflow::handle_flow_route, this, _1));
Disposition lavi_hostflow::handle_flow_route(const Event e).2, "One of the lavi component (though I forgot which one) will listen for that event and send a message to ENVI. "
- lavi_hostflow inherit lavi_flows, so lavi_hostflow has JSONmsg_event handler.I think JSONmsg_event handler seems to check type, command, node_type.if command is request, send_list-send_flow_list(reply add)
if subscribe , interested.push_backif unsubscribe, interested.erase,so, I don't know flow_route_event is run at some point, register_handlerJSONMsg_event (boost::bind(lavi_flows::handle_req, this, _1));

Hi,This is a standard procedure in NOX. You need to include the header file for the definition of the event, then create the event, populate it and post it. One of the lavi component (though I forgot which one) will listen for that event and send a message to ENVI. Look at lavi_hosts (I think) for an example.

Hi All,I am currently trying to understand relation between LAVI and ENVI.
especially, I am looking at part of lavi_flow and lavi_hostflow to add and delete on ENVI.To handle event such as add and delete flows on ENVI,I think I should generate Handle_flow_route event in netapps/lavi/lavi_hostflow.cc.
so, how can I generate handle_flow_route event ? or where does it operate the event ?

At the end, you have some new code starting with "of_port_stats psrep;". Did you simply add that code to the end ofsend_stat_req()? If so, it's not going to work. The request is sent bysend_openflow_command(), but the answer does not come back immediately. psrep will not be filled in. Instead, you need to wait for an event to be fired when you receive the response from the switch. In linkload, this happens in thehandle_port_stats() method, which iterates over Port_stats structures (basically the same as ofp_port_stats structures from the packing library). Your code belongs somewhere in the loop in that function.Hope that helps.-- MurphyOn Jul 7, 2011, at 11:37 PM, Min-Hyup KANG wrote:Hi all,I am currently trying to get any statistics of running switch.and I am re-writing some networkstate/linkload.cc as blow, but I think their value is "0"I need your help and any suggestion would help me.Thanks,void linkload::send_stat_req(const datapathid dpid, uint16_t port) { size_t size = sizeof(ofp_stats_request)+sizeof(ofp_port_stats_request); of_raw.reset(new uint8_t[size]); of_stats_request osr(openflow_pack::header(OFPT_STATS_REQUEST, size),OFPST_PORT, 0); of_port_stats_request opsr; opsr.port_no = OFPP_NONE; osr.pack((ofp_stats_request*) openflow_pack::get_pointer(of_raw)); opsr.pack((ofp_port_stats_request*) openflow_pack::get_pointer(of_raw, sizeof(ofp_stats_request))); /

I believe more SNAC discussion takes place on the openflow-discuss mailing list than here, so you might have more luck there than on the nox mailing list. It looks like your main problems may just be with the packaged versions of SNAC, and you may have better luck building from source. SNAC maintains their own fork of an old NOX.

[nox-dev] NOX, FlowVisor, SNAC qeustion
Dear All, I have a basic question. I am planning to run controller for SNAC.(OS:Ubuntu Server version 10.10). but If I run NOX, SNAC, I know FlowVisor should run. Is it right ? so, I installed NOX(0.6) FlowVisor(git clone git://openflowswitch.org/flowvisor.git) and I use Pronto 3290 Openflow Switch. 1.Can I run NOX,SNAC and FlowVisor on A PC ? 2. What Should I install SNAC version ? 0.8.9 ? 1.0 ?
