Hi,
I want implement following scenario add same flow, but don't know how to add
ARP and ICMP flow
can any one let me know what will be ARP and ICMP flow for following scenario.
I have OpenvSwitch installed in a computer that has a
quad port. eth3, eth4 and eth5 are connected to br0 with respective open flow
port numbers as 3,2,1 and the respective IP addresses of the machines connected
to the ports are 10.6.3.2, 10.6.1.2 and 10.6.2.2
I use eth3 and eth4 i.e ports 2 and 3 as input port and eth5 (port 1) as output
port of OvS. I created 2 queues at eth5 using the following command:
I then added the following flows in the flow table:
ovs-ofctl add-flow br0
"in_port=2,dl_type=0x0800,nw_proto=6,nw_src=10.6.1.2,nw_dst=10.6.2.2,tp_dst=6000,priority=7,actions=enqueue:1:0"
ovs-ofctl add-flow br0
"in_port=3,dl_type=0x0800,nw_proto=6,nw_src=10.6.3.2,nw_dst=10.6.2.2,tp_dst=6005,priority=7,actions=enqueue:1:1"
ovs-ofctl add-flow br0
"in_port=1,dl_type=0x0800,nw_proto=6,nw_dst=10.6.1.2,nw_src=10.6.2.2,tp_src=6000,priority=5,actions=output:2"
ovs-ofctl add-flow br0
"in_port=1,dl_type=0x0800,nw_proto=6,nw_dst=10.6.3.2,nw_src=10.6.2.2,tp_src=6005,priority=5,actions=output:3"
ovs-ofctl add-flow br0
"in_port=2,dl_type=0x0800,nw_src=10.6.1.2,priority=0,actions=output:1"
ovs-ofctl add-flow br0
"in_port=3,dl_type=0x0800,,nw_src=10.6.3.2,priority=0,actions=output:1"

Please can give me example like what will be in output ?
curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"ICMP", "cookie":"0",
"priority":"1", "ether-type":"0x800", "active":"true", "actions":"output=
????"}' http://10.222.41.37:8085/wm/staticflowentrypusher/json
curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"ARP", "cookie":"0",
"priority":"1", "ether-type":"0x806", "active":"true", "actions":"output=
???"}' http://10.222.41.37:8085/wm/staticflowentrypusher/json
curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"port", "cookie":"0",
"ether-type":"0x0800" ,"dest-ip":"10.0.0.1", "protocol":"6",
"active":"true","dst-port":"8888", "actions":"output=1"}'

Hi Suresh,
You could try by pushing flows for first ARP, where dl_type is 0x806 and for IP
second. I mean before pushing the flows for IP as you told, try pushing flows
for ARP first.

can any one tell me what will be match case and action for ARP AND ICMP packet.
for following senario h1-s1-h2
h1(10.0.0.1 running server on port 8888) -s1-h2(10.0.0.2 running one client)
