Dear colleagues, I am Yoshihiko Kanaumi, a researcher at NICT Japan for the operation and management of networks. Now I'm working on a project to built a nation wide OpenFlow testbed on JGN2plus network.
I'm elementary programmer of Ptyhon and C/C++. So, I'd like to have your advices and helps about NOX. 1. I'd like to get entire FDB tables of all OpenFlow switches via NOX. I try to get FDB table (MAC address table ) information through MIB, but it depends on switches implementations. So I wonder if there's a way to get such information via NOX, because NOX maintains all Flow table information in the network. Does someone show me how to do so ? Or is there any ways to do the equivalent operation ? 2. I'd like to refine the "spanning_tree" module. I found the current spanning_tree module at OpenFlow wiki-page and added to my own NOX box. I found that the module does not update the network topology information when I down and up one of the links and/or a port recovers from a failure. Does anyone know how to improve this, or is there any sophisticated spannning_tree modules? If I am to do so by myself, should I modify "def update_spanning_tree_callback(self, links)" ? I am envisionning to try to implement RSTP and MST to NOX, and enhance L2 control protocols further. I would appreciate your help. Thanks ! Kanaan. _______________________________________________ nox-dev mailing list [email protected] http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
