Deleting Flows from OVSK and CPqD Switches

Start Mininet and on on Mininet console execute "pingall" which creates 2 default flows part of Table Zero.

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".
