[nox-dev] A general question regarding discovery module
It seems this module will periodically construct the topology. I dont know why it will periodically time_out the links. I want to know in what situations the links will time_out. Thanks. ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
Re: [nox-dev] Need help regarding querying statistics from switches
We are recently confirmed the switch itself has some bug, it cant collect byte statistics. Thanks all. On Thu, Dec 10, 2009 at 6:02 PM, Guanyao Huang wrote: > Hello > Sorry to bother others.

[nox-dev] OpenFlow 0x98
Hi, I'm trying to get a version of NOX which is compatible with OpenFlow 0x98. Compiling the version from git://noxrepo.org/nox or git://noxrepo.org/noxcore both give me compile errors about undefined classes when setting --with-openflow to any of 0.8.9r2, 0.9.0 or the openflow git. Can anyone point me at somewhere I can get a newer version of NOX? The specific compiler errors I'm getting (against openflow from git) are: In file included from ../../../src/lib/openflow-event.cc:43: ../../../src/include/flow-expired.hh: At global scope: ../../../src/include/flow-expired.hh:43: error: ISO C++ forbids declaration of ‘ofp_flow_expired’ with no type ../../../src/include/flow-expired.hh:43: error: expected ‘,’ or ‘...’ before ‘*’ token ../../../src/include/flow-expired.hh:58: error: ISO C++ forbids declaration of ‘ofp_flow_expired’ with no type ../../../src/include/flow-expired.hh:58: error: expected ‘;’ before ‘*’ token ../../../src/include/flow-expired.hh:62: error: expected ‘;’ before ‘static’ ../../../src/include/flow-expired.hh: In member function ‘virtual const ofp_match* vigil::Flow_expired_event::get_flow() const’: ../../../src/include/flow-expired.hh:55: error: ‘get_flow_expired’ was not declared in this scope ../../../src/include/flow-expired.hh: At global scope: ../../../src/include/flow-expired.hh:69: error: ISO C++ forbids declaration of ‘ofp_flow_expired’ with no type ../../../src/include/flow-expired.hh:69: error: expected ‘,’ or ‘...’ before ‘*’ token ../../../src/include/flow-expired.hh: In constructor ‘vigil::Flow_expired_event::Flow_expired_event(vigil::datapathid, int)’: ../../../src/include/flow-expired.hh:71: error: ‘ofe’ was not declared in this scope ../../../src/lib/openflow-event.cc: At global scope: ../../../src/lib/openflow-event.cc:68: error: ISO C++ forbids declaration of ‘ofp_flow_expired’ with no type ../../../src/lib/openflow-event.cc:68: error: expected ‘,’ or ‘...’ before ‘*’ token ../../../src/lib/openflow-event.cc: In function ‘vigil::Event*::handle_flow_expired(vigil::datapathid, int)’: ../../../src/lib/openflow-event.cc:72: error: ‘ofe’ was not declared in this scope ../../../src/lib/openflow-event.cc:72: error: ‘buf’ was not declared in this scope ../../../src/lib/openflow-event.cc: In function ‘vigil::Event* vigil::openflow_packet_to_event(vigil::datapathid, std::auto_ptr)’: ../../../src/lib/openflow-event.cc:277: error: ‘OFPT_FLOW_EXPIRED’ was not declared in this scope ../../../src/lib/openflow-event.cc:278: error: no matching function for call to ‘handle_packet(vigil::Event* (&)(vigil::datapathid, int), vigil::datapathid&, const ofp_header*&, std::auto_ptr&)’ Thanks, Daniel ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org

Hi Daniel, Are you compiling NOX for OpenFlow v0.9? Basically, I would like to know where and how you got the OpenFlow source. That will help in resolving your question.

Discovery times out links when no LLDP packets have been received over some timeout period. Timer values are documented within discovery.py. It seems this module will periodically construct the topology. I dont know why it will periodically time_out the links. I want to know in what situations the links will time_out.

Re: [nox-dev] OpenFlow 0x98
Hi, This is probably because --with-openflow is somewhat hard to maintain. We are doing away with it for further versions. If you do not need any specific feature in 0x98, I would recommend going with 0x97 in * openflowswitch.org/openflow (release/0.8.9) * noxrepo.org/nox (do not use --with-openflow option in configure) If you need some particular feature beyond v0.8.9, let us know. We can figure something out then. Hope this is helpful.
