I am not an expert in wireshark so I might be totally wrong here, but I
believe that in the OF wireshark plugin, you have to modify the Makefile
to specify the exact port that you want to use to capture OF control
traffic, in this case port 7777 or it will use the default OF port.
Someone with more experience in the OF wireshark plugin please jump in
if this is inaccurate.

I believe the control traffic is there (look at tcpdump), but for some reason
wireshark isn't showing it if it's on port 7777.

Hi Bob,
I'm running this on the loopback interface in wireshark. I think I see
whats going on.
If I run mn like this I don't see any of traffic in wireshark
sudo mn --custom mytopo.py --topo mytopo --switch ovsk --controller
remote --port 7777
Though If I run it like this I do:
sudo mn --custom mytopo.py --topo mytopo --switch ovsk --controller remote
(Note I do change the port that my controller is running on respectively.)
Now that I can see the OF traffic I may be able to see where I'm going wrong.
Thanks,
Aaron

Hi Aaron,
Which interface are you running wireshark on?
For a controller running inside the VM, you should probably be looking at the
loopback interface.

I'm trying to look at my openflow traffic with wireshark but for some
reason I'm not seeing any. Though at my controller I'm definitely
getting the packets. (I think this may because I'm using mininet? I've
tried all the interfaces on my machine in wireshark). Though when I
try this using the Openflow Tutorial provided VM i'm also not seeing
any 'of' packets in wireshark there? (Any idea why)?
Thanks,
Aaron
