Hi Murphy, Thanks a lot.
After installing zope, I could set the switch to self learning mode loading the pyswitch module. nox_core -i ptcp: pyswitch NOX 0.9.0(zaku)~full~beta (nox_core), compiled Feb 7 2011 08:32:49 Compiled with OpenFlow 0x01 00001|nox|WARN:Ignoring features reply received while in state 'receiving ofmp capability reply' 00003|openflow|WARN:stream: connection closed by peer 00004|nox|WARN:stream: connection closed by peer 00006|nox|WARN:Ignoring features reply received while in state 'receiving ofmp capability reply' Now, as you suggested - I will try using SNAC or add/modify a module (pyswitch) to achieve following - setting flow tables in switch - obtaining first packet of a every new flow from the controller Regards, Vishal On Fri, Feb 4, 2011 at 6:43 PM, Murphy McCauley <jam...@nau.edu> wrote: > Well, that actually appears to be getting components loading.
