Good morning,
I have a question concerning deleting flows. My code is the following:
def del_flow(self, datapath, match):
ofproto = datapath.ofproto
parser = datapath.ofproto_parser
#actions1 = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
ofproto.OFPCML_NO_BUFFER)]
#if actions!=actions1:
mod = parser.OFPFlowMod(datapath=datapath,match=match,
cookie=0,command=ofproto.OFPFC_DELETE,out_port=ofproto.OFPP_ANY,
out_group=ofproto.OFPG_ANY, idle_timeout=0,
hard_timeout=0,priority=2,flags=ofproto.OFPFF_SEND_FLOW_REM)
datapath.send_msg(mod)
# get buffer from the send queue
#buf = datapath.send_q.get()
# send buffer
#datapath.socket.sendall(buf)
print("delete flow %s",datapath.id ,mod)
"""
However, when I try to call del_flow, flows are not deleted. Can you help
me fix this problem??
Thanks in advance,
