Hi Carlos,
What does "split flows" exactly mean?
> req = parser.OFPGroupMod(datapath, ofp.OFPFC_ADD, ofp.OFPGT_SELECT,
> group_id, buckets)
If you specify OFPGT_SELECT, switch will execute "one" bucket in the group and
not copied like the port mirroring. If you intend to do port mirroring, you need
to specify OFPGT_ALL. For other available group types, please refer to the
OpenFlow spec and your switch's specification.
Thanks,
Iwase

Hi there,
I know this topic was discussed before but I would like just a simple
explanation about it.
Because I am using the group table with openflow 1.3 with no sucess.
My purpose is to split one flow in two flows and forward on port 3 and 4 using
the group table.
My code is as follows:
*def group_mod(self, datapath):*
* global ofp, _parser_, dp*
* port_1 = 4*
* queue_1 = _parser_.OFPActionSetQueue(0)*
* actions_1 = [queue_1, _parser_.OFPActionOutput(port_1)]*
*
*
*
*
* port_2 = 3*
* queue_2 = _parser_.OFPActionSetQueue(0)*
* actions_2 = [queue_2, _parser_.OFPActionOutput(port_2)]*
*
*
* weight_1 = 50*
* weight_2 = 50*
*
*
* watch_port = ofproto_v1_3.OFPP_ANY*
* watch_group = ofproto_v1_3.OFPQ_ALL*
*
*
* buckets = [*
* _parser_.OFPBucket(weight_1, watch_port, watch_group,
actions_1),*
* _parser_.OFPBucket(weight_2, watch_port, watch_group,
actions_2)]*
*
*
* group_id = 50*
*
*
* req = _parser_.OFPGroupMod(datapath, ofp.OFPFC_ADD, ofp.OFPGT_SELECT,*
* group_id, buckets)*
*
*
* datapath.send_msg(req)*
*
*
*
*
*
*
Hope this is right.
Could anyone help me with this issue?
