Hi Takahashi,
After following up with openflow-dev
OFPFF_CHECK_OVERLAP works only with OFPFC_ADD for openflow 1.2 and later.
I am using ofctl_rest.py as my controller code and I made the following
change in ofctl_v1_3.py.
def mod_flow_entry(dp, flow, cmd):
cookie = int(flow.get('cookie', 0))
cookie_mask = int(flow.get('cookie_mask', 0))
table_id = int(flow.get('table_id', 0))
idle_timeout = int(flow.get('idle_timeout', 0))
hard_timeout = int(flow.get('hard_timeout', 0))
priority = int(flow.get('priority', 0))
buffer_id = int(flow.get('buffer_id', dp.ofproto.OFP_NO_BUFFER))
out_port = int(flow.get('out_port', dp.ofproto.OFPP_ANY))
out_group = int(flow.get('out_group', dp.ofproto.OFPG_ANY))
* flags = int(flow.get('flags', dp.ofproto.OFPFF_CHECK_OVERLAP)*
match = to_match(dp, flow.get('match', {}))
inst = to_actions(dp, flow.get('actions', []))
.....
Then, I send the flow entries using curl commands
curl -d '{"dpid": "000000000000001","priority": "101","match": {"in_port":
"2"},"actions": [{"type": "OUTPUT", "port": "1"}]}'
http://192.168.219.130:8080/stats/flowentry/add
When I try adding another flow of same priority match I should get
OFPFMFC_OVERLAP
but instead the previous flow is replaced.
Please guide me if I need to make any other changes in the code to set the
OFPFF_CHECK_OVERLAP flag.
Thanks & Regards
Sandhya
