Oh I see - the bindings_storage module would hold that information
from nox.netapps.bindings_storage.pybindings_storage import
pybindings_storage
self.bindings = self.resolve(pybindings_storage)
and then you can use the module's API as defined in netapps/bindings_storage
for example self.bindings.get_all_links() would give you a list with tuples
of the form (src_dpid, src_port, dst_dpid, dst_port)
you can take a look at the code of Glen Gibb's spanning tree
modulehttp://www.openflow.org/wk/index.php/Basic_Spanning_Tree,
which is the only example that comes to my mind that uses the python binding
storage API

Hi Karim,
the second parameter of install_datapath_flow() is a python dictionary
that describes the flow for which you are setting up an entry. This is where
you specify the MAC address(es). Create a dictionary, populate as you want
(the keys for the source and destination addresses are 'dl_src' and 'dl_dst'
respectively. - missing key/value pair equals wildcard for that field), and
pass it to install_datapath_flow.
If you take a look at src/nox/lib/core.py, which defines the python API,
you'll find some information about this in the definition of
install_datapath_flow()

Hi,
I want to set-up statically a path using openflow but the
install_datapath_flow() method does not accept mac address as parameter, so
I need to know the correspondence between mac addresses and port numbers in
a switch so that I can choose the out_port that is correspondent to a mac
address.
Is there any method that allows it ?
Thanks a lot,
Karim

Thanks Kyriakos :)
My question was not very well formulated ;)
I meant in order to set a path I need to know the topology of the openFlow
network, e.g. port 1 of switch 1 is linked to port 1 of switch 2 etc. in
order to decide how to populate the switching table.
Is there any method to get this information ?
Thanks a lot
