Hi Amer: As stated in:
https://openflow.stanford.edu/display/ONL/POX+Wiki#POXWiki-OpenFlowMessages "OpenFlow messages are how OpenFlow switches communicate with controllers. The messages are defined in the OpenFlow Specification. There are multiple versions of the specification; POX currently supports OpenFlow version 1.0.0 (wire protocol version 0x01)." -- Att Lucas Brasilino MSc Student @ Federal University of Pernambuco (UFPE) / Brazil twitter: @lucas_brasilino 2015-02-22 6:40 GMT-03:00 AMER <amer7...@hotmail.com>: > Hello, > > > how to force pox to use openflow 1.3 > > Thank you > > > *Eng Amer Algh1.3ban* > *COE* > *SANS-GCFW* > *CEH, SCNP, CCNA* > > > > Date: Sat, 21 Feb 2015 14:58:13 -0800 > > > From: b...@nicira.com > > To: amer7...@hotmail.com > > CC: d...@openvswitch.org > > Subject: Re: [ovs-dev] Error > > > > Please don't drop the mailing list. > > > > You are clearly using OpenFlow 1.0.
