Are you sure you've got the upgraded version running? Just to make sure so we don't spend time chasing down a dead end, try running this component: http://www.noxathome.org/x/Murphy/switch_info.py
If that does show that you've got the new version running, capture the control traffic using Wireshark/tcpdump or the openflow.debug component (which makes pcap trace files) and post it here. -- Murphy On May 29, 2013, at 11:17 AM, Mayumi Park Campos wrote: > Hi, > > I change de ovs version to de 1.9.0 but I stil get the erro message > > ./pox.py log.level --DEBUG openflow.nicira --convert-packet-in > forwarding.l2_nx > POX 0.1.0 (betta) / Copyright 2011-2013 James McCauley, et al. > INFO:forwarding.l2_nx:Simple NX switch running. > DEBUG:core:POX 0.1.0 (betta) going up... > DEBUG:core:Running on CPython (2.7.3/Aug 1 2012 05:16:07) > DEBUG:core:Platform is > Linux-3.2.0-41-generic-pae-i686-with-Ubuntu-12.04-precise > INFO:core:POX 0.1.0 (betta) is up. > DEBUG:openflow.of_01:Listening on 0.0.0.0:6633 > INFO:openflow.of_01:[00-50-04-9d-16-db 1] connected > ERROR:openflow.of_01:[00-50-04-9d-16-db 1] OpenFlow Error: > [00-50-04-9d-16-db 1] Error: header: > [00-50-04-9d-16-db 1] Error: version: 1 > [00-50-04-9d-16-db 1] Error: type: 1 (OFPT_ERROR) > [00-50-04-9d-16-db 1] Error: length: 68 > [00-50-04-9d-16-db 1] Error: xid: 10 > [00-50-04-9d-16-db 1] Error: type: OFPET_BAD_REQUEST (1) > [00-50-04-9d-16-db 1] Error: code: OFPBRC_EPERM (5) > [00-50-04-9d-16-db 1] Error: datalen: 56 > [00-50-04-9d-16-db 1] Error: 0000: 01 04 00 38 00 00 00 0a 00 00 23 20 00 00 > 00 0d ...8......# .... > [00-50-04-9d-16-db 1] Error: 0010: 00 00 00 00 00 00 00 00 fe 00 00 00 00 00 > 00 01 ................ > [00-50-04-9d-16-db 1] Error: 0020: ff ff ff ff ff ff 00 00 00 00 00 00 00 00 > 00 00 ................ > [00-50-04-9d-16-db 1] Error: 0030: 00 00 00 08 ff fb 00 00 > ........ > INFO:forwarding.l2_nx:[00-50-04-9d-16-db 1] ready > > > The thing that I want to do is to install a flow per table so I'm trying to > undestand how does this works > > Tkanks > > > From: [email protected] > To: [email protected] > CC: [email protected] > Subject: RE: [pox-dev] Nicira errors > Date: Tue, 28 May 2013 16:52:47 -0300 > > Thanks Murphy, > > I'm using the ovs 1.4.6.
