Using oflops within mininet

[SachinTS]

Hey guys,

I am New to mininet.
I am working with mininet and ryu controller on ubuntu 14.04 for my university research.
I need to run oflops, but I could not follow the help page.
I started my mininet topology by following command,
sudo mn --controller=remote --switch=ovs --topo=single,3

my interfaces looks like following at this point:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:38:54:10 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.23/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 08:00:27:7d:3d:19 brd ff:ff:ff:ff:ff:ff
6: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default
    link/ether be:cc:e5:24:03:72 brd ff:ff:ff:ff:ff:ff
14: s1-eth1@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master ovs-system state UP group default qlen 1000
    link/ether 1e:68:ad:b6:2d:40 brd ff:ff:ff:ff:ff:ff
15: s1-eth2@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master ovs-system state UP group default qlen 1000
    link/ether 2e:98:1c:35:96:ad brd ff:ff:ff:ff:ff:ff
16: s1-eth3@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master ovs-system state UP group default qlen 1000
    link/ether 6e:ab:f2:88:a3:35 brd ff:ff:ff:ff:ff:ff
17: s1: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default
    link/ether 8e:7d:4c:45:55:49 brd ff:ff:ff:ff:ff:ff

Now how do I initiate oflops from oflops for testing the OVS switch that's part of the mininet topology ?

Thanks
