Hi All,
I am running a python script whose code is shown below and when i'm"
invoking *simple_switch_13.py* on the other side of the terminal i'm
getting the errors as shown below
unsupported version 0x1. If possible, set the switch to use one of the
versions [4] on datapath ('127.0.0.1', 39050)
unsupported version 0x1. If possible, set the switch to use one of the
versions [4] on datapath ('127.0.0.1', 39051)
unsupported version 0x1. If possible, set the switch to use one of the
versions [4] on datapath ('127.0.0.1', 39052)
unsupported version 0x1. If possible, set the switch to use one of the
versions [4] on datapath ('127.0.0.1', 39053)
Further when the same python script is run when invoking *simple_switch.py*
it works fine.The Python script is shown below as
from mininet.node import *
from mininet.net import Mininet,Link
from mininet.cli import CLI
net = Mininet( )
c1 = net.addController('c1',controller=RemoteController)
print("Adding Switches")
s1 = net.addSwitch('s1', cls=OVSSwitch, protocols='OpenFlow13')
s2 = net.addSwitch('s2', cls=OVSSwitch, protocols='OpenFlow13')
s3 = net.addSwitch('s3', cls=OVSSwitch, protocols='OpenFlow13')
print("Adding Host to the Network")
h1 = net.addHost('h1')
h2 = net.addHost('h2')
h3 = net.addHost('h3')
print("Adding links to the network")
net.addLink(h1,s1)
net.addLink(h2,s2)
net.addLink(h3,s3)
net.addLink(s2,s1)
net.addLink(s2,s3)
c1.start()
net.start()
print net.pingAll()
CLI(net)
net.stop()
