Hi, Mehran
Unfortunately, you cannot use the port number which is connected to the
controller in OFPActionOutput().
However, if you can set roles(Master/Slave) to the controllers,
you can use OFPSetAsync to control whether the switch sends Packet-In to
Master or Slave controller:
http://ryu.
Hi, Tahereh
Unfortunately, traffic monitoring at ports connected to its controller
is out of scope of OpenFlow and Ryu.
If you want to do this, I think you should implement your own logic.
Thanks,
Fujimoto

Hi, Tahereh
I reproduced your situation.
I inspected the EventOFPPortStatsReply packets from OVS by using wireshark,
apparently ovs always replies that its max_speed=0 and curr_speed=1000,
regardless of whether pings are send or not.
Ryu seems to get EventOFPPortStatsReply correctly and I th
can make ovsdb handle both IPv4and IPv6 connections.
(through IPv4-mapped address,
https://tools.ietf.org/html/rfc3493#section-3.6 )
Fortunately , I just need to need the IP version of local ip address
instead of local ip itself.

I do " link s1 s2 down", main path will be changed correctly.
I'm using openflow 1.3, Ryu 4.2, ovs 2.5, mininet 2.1. Also, I tried
the app with mininet 2.2 and ovs 2.7 , but the result was similar.
Many thank for your assistance.

Hi, Pynbiang
Thank you for sending your log messages!
In the messages, I've found:
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.
Please run your command with "sudo", that is:

Hi, Mahdieh
You can use "ofproto.OFPP_IN_PORT" to do it.
actions = [parser.OFPActionOutput(ofproto.OFPP_IN_PORT)]
self.add_flow(datapath, 0, match, actions)
Then, the flow shown below will be installed.
$ovs-ofctl -O OpenFlow13 dump-flows s1

Hi, Suhail
Unfortunately, these statistics are out of OpenFlow's scope,
and OpenVSwitch does not seem to provide statistics like these...
I think you need to implement your own application to take statistics.
For example, you need to make your switches to do Packet-In with every
packet,

Could you check 'dl_dst' in the packet, too?
The rule you installed seems to have two match fields, 'dl_vlan' and
'dl_dst':

For further inspection, could you tell me the following? :

* Log messages of Ryu with '--verbose' option
* Diff of rest_firewall.py, if you modified rest_firewall.py

Hi, Edison
Thanks to read our Ryu-book!
And we have another documentation, which describes some detailed
informations.
http://ryu.readthedocs.io/en/latest/index.html
For groups/buckets, here is an example code using SELECT:
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#ryu.
Hi, Mahmoud
Rules are added in FirewallController._set_rule():
https://github.com/osrg/ryu/blob/master/ryu/app/rest_firewall.py#L492-L514
And the variable "rule" has the rule which was inputted via Curl.
You can check this variable to verify whether your rule is valid.
Thanks,
Fujimoto

Hi Fujimoto,
I just want to get the ip address of ovsdb.
I think RemoteOvsdb has enough information and these information
should be available for app developer though EventNewOVSDBConnection
and other events.
