Hi Iwase,
After including module openvswitch, ryu-manager call is able to move
further. But it is still not able to complete things.
instantiating app ryu.controller.ofp_handler of OFPHandler
BRICK SimpleSwitch13
CONSUMES EventOFPSwitchFeatures
CONSUMES EventOFPPacketIn
BRICK ofp_event
PROVIDES EventOFPSwitchFeatures TO {'SimpleSwitch13': set(['config'])}
PROVIDES EventOFPPacketIn TO {'SimpleSwitch13': set(['main'])}
CONSUMES EventOFPPortStatus
CONSUMES EventOFPSwitchFeatures
CONSUMES EventOFPErrorMsg
CONSUMES EventOFPPortDescStatsReply
CONSUMES EventOFPEchoRequest
CONSUMES EventOFPEchoReply
CONSUMES EventOFPHello
connected socket:<eventlet.greenio.base.GreenSocket object at
0x7fab639f1610> address:('127.0.0.1', 32776)
hello ev <ryu.controller.ofp_event.EventOFPHello object at 0x7fab639eb810>
move onto config mode
EVENT ofp_event->SimpleSwitch13 EventOFPSwitchFeatures
switch features ev
version=0x4,msg_type=0x6,msg_len=0x20,xid=0xcd66c812,OFPSwitchFeatures(auxiliary_id=0,capabilities=79,datapath_id=1,n_buffers=256,n_tables=254)
move onto main mode
In ryu book, it has mentioned that some time will take to get connected to
OVS. But I have waited for 30 mins and still hung over here.
Following are the last syslog messages I got in the under syslog.
Jul 20 10:26:29 mininet-vm ovs-vswitchd: ovs|00746|rconn|INFO|s1<->tcp:
127.0.0.1:6633: connected
Jul 20 10:26:39 mininet-vm ovs-vswitchd: ovs|00747|connmgr|INFO|s1<->tcp:
127.0.0.1:6633: 1 flow_mods 10 s ago (1 adds).
If you know the error, Please guide me.
Thanks,
Deepak

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
reports.http://sdm.link/zohodev2dev
