Hi KK,
I didn't quite understand how a NAT box is supposed to operate (never made
one before) but I managed to get it working using a logical IP just as you
described below. I might add code for the situation in which the box gets
its IP via DHCP but I think it's fine for now.
Thanks,
Basu
On Mon,
Hi,
I have the same question, but my scenario is different. If you have an
openflow switch and want it to act like a router, you have to answer
arp replies and you need to know each IP address assigned to each
switch interface.
If you don't, you have to include every IP of every interface of every
Hi Shrutarshi,
I am not sure why you would need to get the IP address on the switch
so as to write a NAT application. The IP address assigned to the
switch/NAT box can be logical (i.e., the controller knows about it and
not the switch). The rewriting of the IP addresses, transport ports,
etc. ar

The dp_desc of the switch *may* contain the IP address (no
I'm not sure how you would go about obtaining the switches ip though
nox. Though it think it should be possible to get when the switches
join. Any reason you would need to do that?
One thing I've done is set the dpid of each switch to the ip address
of the switch (in hex padded with 0's).
Also, t
Ahh ok, that makes sense. Since the dpid represents the switch, is there some
way to use it to get more information about the switch (like its IP)? It
doesn't seem like information like this is in the packet.

Hi Shrutarshi,
Each datapathID (dpid) received from a packet in event represents the
switch that the packet came in on.
You just need to do something like this:
def packet_in_callback(dpid, inport, reason, len, bufid, packet):
flow = extract_flow(packet);
inst.install_datapath_flow(dpid, ...
Hi,
I'm using NOX via the Python API. I would like to install multiple new data
path flows as part of a packet_in handler. I am wondering how I can get or
create a new data path ID, or can I reuse the ID that gets sent to the handler?
I haven't been able to find any example where a handler ins
