I am having trouble connecting the switch to the controller in mininet. I use python script.
My script is the following.
The file name is test.py.
#!/usr/bin/python
from mininet.cli import CLI
from mininet.topo import Topo
from mininet.net import Mininet
from mininet.util import dumpNodeConnections
from mininet.node import Controller, OVSSwitch, RemoteController, OVSBridge
from mininet.log import setLogLevel
class test_Topo(Topo):
def build(self):
s1 = self.addSwitch( 's1')
s2 = self.addSwitch( 's2')
h1 = self.addHost( 'h1' )
h2 = self.addHost( 'h2' )
n1 = self.addHost( 'n1' )
self.addLink( s1, s2 )
self.addLink( s1, h1 )
self.addLink( s1, h2 )
self.addLink( s2, n1 )
def test():
topo = test_Topo()
net = Mininet(topo, build=False, waitConnected=True, switch=OVSSwitch, controller=Controller)
c0 = net.addController( 'c0', port=6633 )
c1 = net.addController('c1', port=6634)
net.build()
s1 = net.get('s1')
s2 = net.get('s2')
c0.start()
c1.start()
s1.start([c0])
s2.start([c1])
net.start()
net.pingAll()
CLI( net )
net.stop()
if __name__ == '__main__':
setLogLevel('info')
test()
I want to have each switch connected to a different controller.
I ran the script with the following command.
sudo python3 test.py
The result is the following.
*** Creating network
*** Adding hosts:
h1 h2 n1
*** Adding switches:
s1 s2
*** Adding links:
(s1, h1) (s1, h2) (s1, s2) (s2, n1)
*** Configuring hosts
h1 h2 n1
*** Starting controller
c0 c1
*** Starting 2 switches
s1 s2 ...
*** Waiting for switches to connect
The connection does not end permanently after the message
*** Waiting for switches to connect
is displayed.
I referred to this code. https://github.com/mininet/mininet/blob/master/examples/controllers.py https://github.com/mininet/mininet/blob/master/examples/controllers2.py
I can't understand why switch can't connect the controller in my code. I apologize for my poor English.
