I guess you actually mean the code from your first letter with
ofproto_v1_5_parser.OFPBucket class:
def send_group_mod(self, datapath):
ofp = datapath.ofproto
ofp_parser = datapath.ofproto_parser
port = 1
max_len = 2000
actions = [ofp_parser.OFPActionOutput(port, max_len)]
weight = 100
#watch_port = ofproto_v1_5.OFPP_ANY
#watch_group = ofproto_v1_5.OFPQ_ALL
bucket = datapath.ofproto_parser.OFPBucket(bucket_id=1,
actions=actions, properties=None, len_=32,action_array_len=None)
buckets = [bucket]
#buckets = [ofp_parser.OFPBucket(weight, watch_port,
watch_group,actions)]
group_id = 1
command_bucket_id = 1
req = ofp_parser.OFPGroupMod(datapath, ofp.OFPGC_ADD,
ofp.OFPGT_SELECT, group_id,
command_bucket_id, buckets)
datapath.send_msg(req)
Its important because struct ofp_bucket was changed dramatically in OFP
1.5.x:
https://www.opennetworking.org/wp-content/uploads/2014/10/openflow-switch-v1.5.1.pdf
(OFP 1.5.1 switch spec., page 115)
Here is the OVS src line from which you've got the error:
https://github.com/openvswitch/ovs/blob/master/lib/ofp-group.c#L2195
So, you shouldn't set command_bucket_id in OFPGroupMod constructor (it
defaults to OFPG_BUCKET_ALL) (spec., page 115).
And after that you should read Ryu docs and OFP 1.5 specs to form correct
bucket properties with desired behavior (watch_port and watch_group)
I hope this would help.
Also, as a sidenotes:
- len_ and action_array_len arguments of OFPBucket.__init__ are not used
for now, and I hope will not be ever;
- you probably shouldn't use max_len for OFPActionOutput when you dont
forward packet to a controller.
