Sorry to bother you again! But I would basically like to only add forwarding
rules for flows as you saw in my previous mail.
But when I am testing it out now ping get stuck at ARP requests.
1) What other apps should I initialize with my ryu-manager (other than
ryu.app.otctl_rest) so that the controller deals with ARP requests in the
beginning for example without installing any actual flow forwarding rules (i.e.
h1 cannot ping h4 until I add in all dedicated switches the correct flow rules
(see previous email))
2) I was also wondering if there is a way to control the hosts and nor only the
switches (I am using mininet). For example let's say I have host h1 that is
connected to both s1 and s2 and when h1 pings h4 I want it to pass by s1 and
not s2. My solution was to only add forwarding rules in s1 and not s2, is that
enough?
Thank you in advance,
I apologize if the questions seem stupid but I am pretty new to this,
Best,
Sherif

Hi, Fahmy
"match" must be a dict, so the following command will be accepted.
curl -H "Content-Type: application/json" -X POST -d '{"dpid": 2,
"cookie": 42, "priority": 45000, "match": {"nw_src":
"10.0.0.1","nw_dst":"10.0.0.4"}, "actions": [{"type":"OUTPUT", "port": 4}]}'
http://localhost:8080/stats/flowentry/add
---
FYI, this rule will not be registered to your switch, because "dl_type" is not
specified.
In OpenFlow 1.0, "dl_type" must be specified to 2048 if you want to match
packets with "nw_src" and "nw_dst".
The following command will be work well:
curl -H "Content-Type: application/json" -X POST -d '{"dpid": 2,
"cookie": 42, "priority": 45000, "match": {"nw_src":
"10.0.0.1","nw_dst":"10.0.0.4","dl_type": 2048}, "actions":[{"type":"OUTPUT",
"port": 4}]}' http://localhost:8080/stats/flowentry/add
Thanks,

Good Evening?,
I am currently using RYU for a proof on concept for my master thesis and I am
facing a problem:
When i intialize tyu-manager with just the ryu.app.ofctl_rest I try to curl
some rules and for some reason if I try to match more than one field it doesn't
work and tells me Attribute Error!
For example this works: ( Match IP source)
curl -H "Content-Type: application/json" -X POST -d '{"dpid": 2, "cookie": 42,
"priority": 45000, "match": {"nw_src": "10.0.0.1"}, "actions":
[{"type":"OUTPUT", "port": 4}]}' http://localhost:8080/stats/flowentry/add
While this DOES NOT: (? Match IP source AND DESTINATION)
curl -H "Content-Type: application/json" -X POST -d '{"dpid": 2, "cookie": 42,
"priority": 45000, "match": [{"nw_src": "10.0.0.1","nw_dst":"10.0.0.4"}],
"actions": [{"type":"OUTPUT", "port": 4}]}'
http://localhost:8080/stats/flowentry/add
DOES THAT MEAN RYU CONTROLLER CAN ONLY MATCH ONE FIELD?? THANK YOU
Thanks in advance,
Best,
Sherif
