[nox-dev] FW: Help: LAVI and NOX's nox-gui.py
Hi~ alls, I used LAVI and nox-gui.py(another front-end as ENVI), and tested some cases with NOX and openvswitch, one switch links to one host, my cmd is "$ ./nox_core -v -i ptcp:6633 monitoring pyswitch lavi ", but there's no host icon and hs2sw link in nox-gui's view, just swicth icon. Could someone help me... --- thanks a lot ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev
Re: [nox-dev] Linkdown Event
Given that this is a status flag, presumably the presence of it means the link is down, and the absence of it means the link is up. Z.

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 is no such flag.

[nox-dev] Watch inside the IP Option field with Openflow
Hi all. I am trying to do some experiments with Openflow. And I would like to know if it is possible to watch inside the IP Header Option field? There is ip header length. So I can find that there is header option. But How do I watch inside the IP Header Option? If I read the IP option something like 'x.x.x.x', then I will modify destination's address. Can I do this in nox controller? Thank you! Hope you could help me - Hyogi ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev
Re: [nox-dev] FW: Help: LAVI and NOX's nox-gui.py
Hi, the hosts should appear when they talk to the network. Did you try generating some traffic? A simple ping should do it (btw, I think "lavi" is not required as an argument as IIRC it's a dependency of monitoring anyway) On Fri, Dec 2, 2011 at 1:21 AM, ztom wrote: > > Hi~ alls, > I used LAVI and nox-gui.py(another front-end as ENVI), and tested some > cases with NOX and openvswitch, one switch links to one host, my cmd is "$ > ./nox_core -v -i ptcp:6633 monitoring pyswitch lavi ", but there's no host > icon and hs2sw link in nox-gui's view, just swicth icon.

Re: [nox-dev] FW: Help: LAVI and NOX's nox-gui.py
Oh, also, there is one component that is responsible for tracking host traffic, and that's what feeds the host information to LAVI and eventually to the GUI I can't remember if it is there as a dependency, so you might need to run that manually. I think the name is "trackhost_pktin" (can't check right now unfortunately). So maybe try adding that too after "monitoring" and "pyswitch" ?
