Whether you post it here or elsewhere, that error message is not that helpful.
If you get a stack trace, you should post the whole thing.

I'd suggest you look at the packets. There's a packet dump app in POX, or you
could use wireshark on the control channel (and/or on one of the host
interfaces).
Though you should still see at least two (the ping and the pong).

Ping sends packets from A to B, and B sends them back to A. Ping does this
continually until you stop it unless you specify a limit on the commandline.
Since you're installing flows, you'd actually expect them to start hitting the
flow table and stop hitting the switch, but the fewest you could

You asked essentially the same question a few days ago. I gave you

Hi all,
The last weeks I been having this problem and I don't know how to fix it. I
been trying to emulate an openflow switch in a PC with Ubuntu 12.04, this pc
has three NIC with this configuration: eth0

No no, I got you point regarding queues. I am talking about flow entries in
flow table e.g lets say that flow entries reach 40 then is there anyway to
delete entries from flow table by sending some sort of command from remote
controller. and how that command should be initiated?

When what reaches a limit? The flow table size? Or are you
You do...
session.query(exists().where(SourcetoPort.src_address ==
str(packet.dst))).scalar()
Do exists() queries always return true or false? In that case, your if
statement would ALWAYS be true.
On the other hand, if dropping the exists...
session.query(where(SourcetoPort.src_address == str(
Thanks for your reply.
So, is it possible to delete flow entries from OVS flow table when it
reached some limit by sending some sort of command from POX controller?

Just as a quick sanity check -- are you sure you're running the right version
of Mininet (or at least the latest one)?
You may also find more help on the Mininet mailing list. There's obviously
crossover in users between the two, but this question isn't actually about POX
and is about Mininet.
It sounds like you're talking about monitoring and manipulating the contents of
queues, which is a very fine-grained operation that must operate at very small
timescales. This isn't addressed by OpenFlow and probably isn't suitable for a
remote controller. OpenFlow allows for assigning packets

Hello Everybody,
I am working on queues in OVS and using POX controller. I have created
queues in OVS and am assigning flows to Queues via POX controller. I can

from queue, so that controller tells OVS to delete specific f
I guess the problem is caused by fail_mode of Open vSwitch configuration.
Have you ever checked the fail_mode configuration? Was it secure or
standalone?

The problem in my case is that even 1-2 minutes after having stopped the
POX controller, I still have pings. Despite the fact that there are no
flows in the flow table, I still have pings.
In order to stop having pings I need to delete the bridge from the switch
and recreate it again.
