Nitish,
i was trying to do something like i guess.
But i am trying to edit the swith handler, as i want the table miss to be
with the meter!
Following you question:
First you need to reate the meter:
For my it i slike this:
rate=25
burst_size=0
bands=[]
bands.append(parser.OFPMeterBandDrop(rate, burst_size))
meter_mod = parser.OFPMeterMod(
datapath,command=ofproto.OFPMC_ADD,flags=ofproto.OFPMF_PKTPS ,meter_id=1,
bands=bands)
datapath.send_msg(meter_mod)
And now you have a meter instaled! You need to edit to the meter type and
parameters you want! i just gave an exampe of adding a meter! (Sorry not
much time)
And now you need to add a flow with this meter in instructions:
match = parser.OFPMatch()
pre_actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
ofproto.OFPCML_NO_BUFFER)]
actions =
parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,pre_actions)
*meter_inst = parser.OFPInstructionMeter(meter_id=1)*
mod = parser.OFPFlowMod(datapath=datapath, priority=0, match=match,
instructions=[meter_inst,actions])
datapath.send_msg(mod)
Again, in my example i edit the table miss as you can see the match with
nothing to match.
Hope i helped you..
If you need more help let me know!
I am stuck now with muitiple tables....
