Check within the switch if the configuration has been submitted correctly.
I've been doing that using OVS commands directly within the switch like
this:
def configureOVSdb(switches):
i = 1
for switch in switches:
s = 's' + str(i)
info('*** Configurando OpenFlow13 en ' + s)
switch.cmd( 'ovs-vsctl set Bridge ' + s + ' protocols=OpenFlow13' )
info('*** Configurando OVSDB port')
switch.cmd( 'ovs-vsctl set-manager ptcp:6632' )
i = i + 1
.....
class MyTopo( Topo ):
"Test topology"
def build( self, **opts ):
# add switches
s1 = self.addSwitch( 's1' )
s2 = self.addSwitch( 's2' )
# add hosts
h1 = self.addHost( 'h1' )
h2 = self.addHost( 'h2' )
self.addLink( h1, s1 )
self.addLink( h2, s2 )
self.addLink( s1, s2 )
def run():
topo = MyTopo()
# Defining remote controller (Ryu)
controller = RemoteController( 'c0', ip='127.0.0.1', port=6633 )
net = Mininet( topo=topo, controller=controller, autoSetMacs=True )
net.start()
# Enviroment settings
controllerUrl = controller_query('0.0.0.0', '8080')
# Get nodes - could be built with for in the future
[s1, s2] = [net.get('s1'), net.get('s2')]
[h1, h2] = [net.get('h1'), net.get('h2')]
switches = [s1, s2]
hosts = [h1, h2]
ports = ['5001', '5002', '5003']
time = 20
sleep(3)
# Configurar protocolo y manager - could be a method
configureOVSdb(switches)
