I made sure OpenFLow1.5 is enabled in switch and I'm running ovs 2.10.90
now. I checked the ovs-vswitchd.log file and got.
ovs-vswitchd.log:
2019-01-08T11:25:09.292Z|00182|rconn|INFO|br0<->tcp:10.0.0.6:6633: connected

sending OFPGMFC_BAD_BUCKET error reply to OFPT_GROUP_MOD message
code:
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 = 0
watch_group = 0
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)
Please let me know what's wrong here? I have tried bucket command id
of 0 and hundred, nothing works.
