i am building load balancer application and the following error is displayed.
please, help me to fix this?
this is some of code:
match = ofp_parser.OFPMatch(in_port=in_port,
eth_type=eth.ethertype, eth_src=eth.src,
eth_dst=eth.dst,
ip_proto=iphdr.proto, ipv4_src=iphdr.src,
ipv4_dst=iphdr.dst)
actions = [ofp_parser.OFPActionSetField(eth_dst=selected_server_mac),
ofp_parser.OFPActionSetField(ipv4_dst=selected_server_ip),
ofp_parser.OFPActionOutput(selected_server_outport) ]
inst = [ofp_parser.OFPInstructionActions(ofp.OFPIT_APPLY_ACTIONS,
actions)]
mod = ofp_parser.OFPFlowMod(datapath=datapath, match=match,
instructions=inst, buffer_id=msg.buffer_id)
datapath.send_msg(mod)
