Hello,
I try something similar and I am unable to match the flows.
In datapath_join I install a flow:
actions = [[openflow.OFPAT_OUTPUT, [0, 2]]]
flow ={}
flow[core.IN_PORT] = 1
flow[core.DL_TYPE]=0x0800
flow[core.NW_SRC] = str((10<<24) + (92<<16) + 100)
self.install_datapath_flow(dpid, flow, openflow.OFP_FLOW_PERMANENT,
openflow.OFP_FLOW_PERMANENT, actions, None, openflow.OFP_DEFAULT_PRIORITY,
None, None)
on the switch using dpctl I receive :
cookie=0, duration_sec=11s, duration_nsec=874000000s, table_id=0,
priority=65535, n_packets=1, n_bytes=60,
idle_timeout=15,hard_timeout=0,tcp,in_port=1,dl_vlan=0xffff,dl_vlan_pcp=0x00,dl_src=00:26:b9:69:2a:5b,dl_dst=00:1d:7e:1b:0f:7a,nw_src=10.92.0.100,nw_dst=10.92.0.3,nw_tos=0x00,tp_src=6633,tp_dst=37479,actions=LOCAL
I try to match it in the aggregated stats:
def aggregate_timer(self, dpid):
flow = ofp_match()
flow.wildcard = 0xffffffff
flow.nw_src = (10<<24) + (92<<16) + 100
self.ctxt.send_aggregate_stats_request(dpid, flow, 0xff)
self.post_callback(MONITOR_TABLE_PERIOD, lambda :
self.aggregate_timer(dpid))
but the statistics received are empty. Do you have any idea where I
inserted a mistake?
Thank you a lot!!!
