我试图实现一种方法,阻止特定的流量,从而丢弃数据包。我传递给它数据路径,源IP和目标IP。应用程序检测流程,但流程继续工作,源发送数据,并且dest主机接收数据。我究竟做错了什么?块流/丢包ryu控制器
def drop_flow(self, datapath, ip_src, ip_dst):
ofproto = datapath.ofproto
parser = datapath.ofproto_parser
match = parser.OFPMatch(ipv4_src=ip_src,
ipv4_dst=ip_dst)
inst = [parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS, [])]
mod = parser.OFPFlowMod(datapath=datapath,
command=ofproto.OFPFC_DELETE,
out_port=ofproto.OFPP_ANY,
out_group=ofproto.OFPG_ANY,
match=match, instructions=inst)
print "deleting flow entries in the table "
datapath.send_msg(mod)
谢谢!
