Hi ,
I would like to raise an issue with openvswitch while I executed the github
openflow 1.0 version script and it didn't find the openflow message
(ofp.OFPFF_SEND_FLOW_REM) in openvswitch.
Openvswitch version : openvswitch - 2.3.1
OS version : Ubuntu 14.04 Ttusty
Open flow version : 1.0
And the same script passed without adding /deleting in the script with
Openflow switch.
PFA script details attached .
Kindly let me know your inputs on the same.
Thanks
