Re: [nox-dev] OpenFlow 0x98

Hi, Would you need some features in OpenFlow v0.9 from the NetFPGA? If yes, switch to the openflow-0.9 branch for wire-compatibility. Be warned that this branch is very much in alpha-status. Regards KK 2009/12/18 : > I am trying to use the NetFPGA OpenFlow module with NOX, and unfortunately I

[nox-dev] make check errors

I got NOX 0.6 compiled and then ran some of the tests mentioned in the documentation. Some fail and some succeed so I'm wondering if my installation worked or not. The tests I ran are: ./nox_core -h -- this works fine make check -- fails as shown below ./nox_core tests -- fails with errors shown

Re: [nox-dev] problem downloading nox

Doh! Yes, thats a type-o. My fault, and thanks for pointing that out. I'll update it. It's just a typo in the command. It should say git "clone". On Fri, Dec 18, 2009 at 4:25 PM, Ashish Agarwal > wrote: $ git pull git://noxrepo.org/nox

Re: [nox-dev] A general question regarding discovery module

Yeah, it could be due to high-loss from load (unfortunately). You could try increasing the timeout value in discovery.py. If you don't have dynamic link events, this should be able to survive temporary timeouts. What switches are you using? In my program the discovery module times out link

Re: [nox-dev] A general question regarding discovery module

Hi Guanyao, If by huge data, you mean you are jamming the links with data, then yes that could be the issue. The LLDP packet can be dropped and cause intermittent link timeout. Regards KK 2009/12/18 Guanyao Huang : > In my program the discovery module times out links sometimes, causing > my pro

Re: [nox-dev] A general question regarding discovery module

In my program the discovery module times out links sometimes, causing my program not working well. I will debug to find out details why the link fails. Actually they are not supposed to fail. Maybe it's because of huge data. On Fri, Dec 18, 2009 at 8:41 AM, Martin Casado wrote: > The goal is to d

Re: [nox-dev] A general question regarding discovery module

The goal is to detect link failures, so one would hope that would be the most common failure mode. I assume LLDP packets are sent periodically. If there is no LLDP, what will be the most possible reason? The controller or the switch is too busy? On Thu, Dec 17, 2009 at 3:07 PM, Martin Casado

I am trying to use the NetFPGA OpenFlow module with NOX, and unfortunately I can only get this working on 0x98, which is why I'm trying to get NOX speaking 0x98... On Fri 18/12/09 03:40, "kk yap" yap...@gmail.com wrote: > Hi, > > This is probably because --with-openflow is somewhat hard to main

Re: [nox-dev] A general question regarding discovery module

Hi Guanyao, Does no LLDP means "no LLDP sent" or "no LLDP received"? Take a look at wireshark. Regards KK 2009/12/18 Guanyao Huang : > I assume LLDP packets are sent periodically. If there is no LLDP, what > will be the most possible reason? The controller or the switch is too > busy? > > On Th
