[Ryu-devel] regarding mismatch error between switch in Mininet wifi andthe controller

[Alka S. <alk...@gm...>]

Good evening


I am new to ryu controller , I am running a topology of mobile nodes
in mininet wifi . whenever i run a file having inside ryu controller
which is using openflow 1.3, I get an error as


mininet@mininet-vm:~/ryu$ ryu-manager ryu.app.simple_switch_13
loading app ryu.app.simple_switch_13
loading app ryu.controller.ofp_handler
instantiating app ryu.app.simple_switch_13 of SimpleSwitch13
instantiating app ryu.controller.ofp_handler of OFPHandler
unsupported version 0x1. If possible, set the switch to use one of the
versions [4] on datapath ('127.0.0.1', 45402)
unsupported version 0x1. If possible, set the switch to use one of the

versions [4] on datapath ('127.0.0.1', 45404)



I am using open virtual switch as 2.13.3 which has support for
openflow 1.3 , so if both controller and my mininet wifi support this
version , Why i am getting this error ?


I have also set openflow protocol version 1.3 manually in the terminal
as I read somewhere that switches default openflow version in 1 the
command i used to set openflow version 1.3 is


sudo ovs-vsctl set bridge dr5 protocols=OpenFlow13



Kindly help to resolve the issue


Thanks and regards
