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
