Thanks for your help!
I have being looking for NXST_FLOW and nx_flow_stats_request which you
mentioned last time all the day,and only find them in open vswitch's
nicira-ext.h,but in ryu I found nothing.And you know if you want to find a
ipv4 flow table,you can use OFPFlowStatsRequest() in ryu's
ofproto_v1_0_parser.py
-------------------code--------------------------------------------------------------------------------------------------
@_set_msg_reply(OFPFlowStatsReply)
@_set_stats_type(ofproto_v1_0.OFPST_FLOW, OFPFlowStats)
@_set_msg_type(ofproto_v1_0.OFPT_STATS_REQUEST)
class OFPFlowStatsRequest(OFPFlowStatsRequestBase):
def __init__(self, datapath, flags, match, table_id, out_port):
super(OFPFlowStatsRequest, self).__init__(
datapath, flags, match, table_id, out_port)
-----------------------------------------------------------------------
and in ofproto_v1_0.py, you have defined OFPT_STATS_REQUEST,but for nicira
extention there are only
--------------------------------------------------------------
# enum nicira_type (abridged)
NXT_ROLE_REQUEST = 10
NXT_ROLE_REPLY = 11
NXT_SET_FLOW_FORMAT = 12
NXT_FLOW_MOD = 13
NXT_FLOW_REMOVED = 14
NXT_FLOW_MOD_TABLE_ID = 15
NXT_SET_PACKET_IN_FORMAT = 16
NXT_PACKET_IN = 17
NXT_FLOW_AGE = 18
NXT_SET_ASYNC_CONFIG = 19
NXT_SET_CONTROLLER_ID = 20
----------------------------------------------
so I can't find NXST_FLOW,if I want to send a request in NXST_FLOW form
from the controller,what should I do?Should I define the NXST_FLOW label
first?
Best Regards!
