Hi,
If you want to match packets, you must satisfy the prerequisites.
For example, if you want to match packet based on source IPv4 address,
you must specify "eth_type" as the prerequisite (in OpenFlow V1.0,
"dl_type").
In the OpenFlow Spec, you can see the prerequisites for each match field:
With OpenFlow v1.3.5, for example, you can see them in the "Header match
fields details." table.
https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-switch-v1.3.5.pdf
So, the code below works as you want:
match = parser.OFPMatch(ipv4_src="10.0.0.1", eth_type=0x0800)
Thanks,
Fujimoto

Using Internal calls, no flow is added and no error OFPError message
actions = [parser.OFPActionSetQueue(2)]
inst = [parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,
actions),
parser.OFPInstructionGotoTable(3)]
match = parser.OFPMatch(ipv4_src="10.0.0.1")
flow = parser.OFPFlowMod(datapath=datapath, priority=200, match=match,
instructions=inst, table_id=1)
flow.datapath = datapath
datapath.send_msg(flow)
But when I change match field to anything else line eth_src, in_port,
flow is added successfully.
Using REST api, successfully added flow
{
"dpid":1,
"table_id": 1,
"match": {
"dl_type": 2048,
"nw_src": "10.0.0.2"
},
"actions": [
{
"type":"GOTO_TABLE",
"table_id":3
},
{
"type":"SET_QUEUE",
"queue_id":2
}
]
}
Flow is added successfully
How to add flow with match field only based on IPv4.
