To see the flows use
sudo ovs-ofctl -O OpenFlow13 dump-flows s1
To delete flows
sudo ovs-ofctl del−flows switch
sudo ovs-ofctl del−flows switch [flow]
With only a switch argument, deletes all flows. Otherwise, deletes flow entries that match the specified flows.
sudo ovs-ofctl del−flows s1 "table=0"
Deleting flows from CPqD switch
sudo dpctl unix:/var/run/s1.sock flow-mod cmd=del,table=0
We can also use "del-flows".
