Hello,
I was trying to use mininet using source build OVS (from master) + pox
controller. Found ovs-dpctl command does not return any output when node 1
tries to ping node 2.
deb7:~/work$ sudo ovs-dpctl show
system at ovs-system:
lookups: hit:0 missed:4776 lost:0
flows: 0
port 0: ovs-system (internal)
port 1: s1 (internal)
port 2: s1-eth1
port 3: s1-eth2
deb7:~/work$
deb7:~/work$ sudo ovs-dpctl dump-flows
<<<< No output here >>>>>
deb7:~/work$
After analysing found below errors in switched log.
