[nox-dev] "attempt to reuse the buffer"

Hello, I have a problem in the communication between an OpenFlow switch (I use OpenVswitch) and my NOX controller, connected out-of-band. The two machines connects, but, after I install the first flow, I get the following error message: *openflow-event|ERR:received Openflow error packet from d

Re: [nox-dev] help: link_type

I'm not an LAVI expert, but I believe the only types are all, sw2sw and host2sw. -- Murphy On Dec 1, 2011, at 12:48 AM, ztom wrote: > Hi~ alls, > I need to get all link_types of topo's jsonmsg, but i just find two of them > ("all" & "sw2sw"). Is there some docs about it? I can't get any hint fr

[nox-dev] Linkdown Event

Hi, If physical link is down (i.e. Cable is removed), what event is generated by openflow. Is it the same as PORT_DOWN event? Thanks in advance. Regards, Harshil Shah, Convergence Lab, Infosys Labs Infosys | Bangalore Mob # : +91 97428 87966. CAUTION - Disclaimer *

Re: [nox-dev] "attempt to reuse the buffer"

Your first call to install_datapath_flow() in the code below is wrong. The last argument you're passing is priority. But the parameter at that position is buffer_id. So what you're actually doing is telling the switch to use buffer_id 5 over and over. Either insert a "None" between actions a

Re: [nox-dev] Linkdown Event

Re: [nox-dev] Not able to send ARP Reply in C++

Re: [nox-dev] Linkdown Event

Thanks Zoltan for a quick reply. One more thing I wanted to ask is: If I connect cable again . So is the same message going with OFPAT_PORT_STATUS with ofp_phy_port with different flag value. Because I checked in openflow.h, there is flag for Down event: OFPPS_LINK_DOWN but for Up event, there i

[nox-dev] how to display network topology timely
