Hi Shivani,
Sorry for the delay.
I sniffed the OpenFlow messages which the "ovs-ofctl" command sent.
The "ovs-ofctl" command seems to send the OFPGC_ADD message with
"command_bucket_id=ofproto.OFPG_BUCKET_ALL" when you invoked:
$ ovs-ofctl -O openflow15 add-group br_test
group_id=3,type=all,bucket=output:2
But, Ryu will send the OFPGC_ADD message with "command_bucket_id=0" (by the
default),
so the first OFPGC_ADD message from Ryu will fail and also fail the following
OFPGC_INSERT_BUCKET
message.
I guess we need to specify "command_bucket_id=ofproto.OFPG_BUCKET_ALL" to send
the OFPGC_ADD
message, and then send the OFPGC_INSERT_BUCKET message after that.
Example:
buckets = [
parser.OFPBucket(
bucket_id=0,
actions=[parser.OFPActionOutput(1)],
),
parser.OFPBucket(
bucket_id=1,
actions=[parser.OFPActionOutput(2)],
),
]
req = parser.OFPGroupMod(
datapath,
command=ofproto.OFPFC_ADD,
type_=ofproto.OFPGT_SELECT,
group_id=1,
command_bucket_id=ofproto.OFPG_BUCKET_ALL,
buckets=buckets)
datapath.send_msg(req)
match = parser.OFPMatch(in_port=3)
actions = [parser.OFPActionGroup(1)]
self.add_flow(datapath, 0, match, actions)
buckets = [
parser.OFPBucket(
bucket_id=2,
actions=[parser.OFPActionOutput(3)],
),
]
req = parser.OFPGroupMod(
datapath,
command=ofproto.OFPGC_INSERT_BUCKET,
type_=ofproto.OFPGT_SELECT,
group_id=1,
command_bucket_id=ofproto.OFPG_BUCKET_LAST,
buckets=buckets)
datapath.send_msg(req)
Hmmm... I think it better to change the default value of "command_bucket_id" to
"OFPG_BUCKET_ALL".
Thanks,
Iwase

Hi Iwase Yusuke,
Thank you for responding.
I have tried the way suggested
command_bucket_id= ofp.OFPG_BUCKET_LAST
i still see an issue, when i see the logs i get the following error :

Hi Shivani,
You seems to specify "command_bucket_id" field like;
command_bucket_id='last'
but I guess you need to specify one of the following constants for this
field.

Example)
command_bucket_id = ofp.OFPG_BUCKET_LAST

Hi,
I am using OpenFlow Version 1.5 and I have tried to use the
Insert_Bucket and Remove_Bucket
commands which are supported in the following version,
On the OVS side i have followed the following steps:
ovs-ofctl -O openflow15 add-group br_test
group_id=3,type=all,bucket=output:2
ovs-ofctl -O openflow15 insert-buckets br_test
group_id=3*,command_bucket_id=first,*bucket=bucket_id:1,actions=output:1
But when i try insert a bucket from RYU I see following issues when
I am try to set
value for command_bucket_id as 'last/first' in my code:
group_id = 1
command_bucket_id='last'
actions = [parser.OFPActionOutput(2)]
buckets = [parser.OFPBucket(actions= actions,bucket_id =1)]
req = ofp_parser.OFPGroupMod(datapath, ofp.OFPGC_INSERT_BUCKET,
ofp.OFPGT_SELECT, group_id,
command_bucket_id, buckets)
datapath.send_msg(req)
it throws the following error:

req = ofp_parser.OFPGroupMod(datapath, ofp.OFPGC_INSERT_BUCKET,
ofp.OFPGT_SELECT, group_id,
command_bucket_id, buckets)
datapath.send_msg(req)
I don't see any error message but the group is not getting added on the
OVS if i check the
logs i see the following error:
Error from the logs :
command_bucket_id (1) is out of range
sending OFPGMFC_BAD_BUCKET error reply to OFPT_GROUP_MOD message
Kindly suggest the correction that need to be make to overcome the
following issue.
Thanks,
Shivani.
