In OpenFlow 1.0, an unmatched packet is sent to the controller. This is
described on page 2 of the OpenFlow 1.0 specification.

Thanks again Murphy.
So ofp_match typically creates a filter for further packets to 'match'
against.
if incase a match is not created , then by default, the switch drops the
'msg' from controller ..is it? or does it matching all the packets when
there is no match ?
I am thinking on terms of ACLs
I tried to recreate the experiment you describe, and it seems to work fine:

Where am I going wrong?
Note that depending on configuration, discovery and l2_multi may require a
little time after startup before things will work (for a complete round

Thanks a lot Murphy I did it.
I was trying to find number of flows. I declared flow as variable and
number of flows is flow value in that variable. I was trying to pass value
from one file to another. I came up with an idea and did it accordingly.
I declared global variable in separate file and the
Can you post your logs from a run of l2_multi that doesn't work?

Hello,
Thank you
I apologize, h1 and h3 are residing in different switch not subnet. h1 10.0.0.1
h3 10.0.0.3.
Also, I tried the following statement and it is work fine:
Pox.py forwarding.l2_learning
I am using tree topology with fan=2

Can you fill us in more on what you're trying to accomplish? It's not clear to
me what your end-goal is (or what you mean by "flow value").

Thanks Alison Chan and Murphy McCauley for your help.
I found number of flows by using

modified by Alison Chan. Now I am facing problem in passing the flow value
which I found, to l2_learning.py in which I have defined queues. Can
hmm.. ok , in l2_learning.py code, why did we 'match' msg with the parsed
packet??
msg = of.ofp_flow_mod()
msg.match = of.ofp_match.from_packet(packet, event.port)
I thought ofp_match() is used only for comparison . But the debug
above shows that, ofp_match() not only compares
I'm afraid I don't follow the issue. Maybe you can post more code and try to
further explain what you think is happening vs. what you think *should* be
happening?

Hmm... as far as I remember, l2_multi and l2_learning shouldn't behave
differently in terms of L3. My memory is that with either of them, you're
likely to run into the same problem -- it's not with POX or OpenFlow or
anything -- it's with the hosts. The hosts will generally expect that they

Hello,
I would like to thank you for your effort in responding to our questions
I used the following command but it does not work
Pox.py l2.multi openflow.discovery
I could not ping between

I tried this one, it works fine:
Pox.py l2.learning openflow.disco
