Hi,
I'm trying to use the pybindings_storage component in order to make my
switch able to learn network topology and, consequently, install the
right entry in the switch's flow-table.
I imported the component like that
from nox.netapps.bindings_storage.pybindings_storage import
pybindings_storage
and, in def install(self): used the self.resolve(pybindings_storage)
def install(self):
self.bindings = self.resolve(pybindings_storage)
self.register_for_datapath_join(self.datapath_join_callback)
self.register_for_packet_in(self.packet_in_callback)
Then, in my packet_in_callback, I want to get information about the
links connected to the switch and then install flows.
As suggested here
http://www.mail-archive.com/nox-dev@noxrepo.org/msg02493.html, I tried
to use
self.bindings.get_all_links()
to get a tuple with the information I need, but I get an error in which
the get_all_links function asks for a parameter.
Reading the nox/src/nox/netapps/binding_storage/pybindings_storage.i
file I see that all that functions need a cb (callback?) parameter
Could someone please clarify me how I have to call that function and
what is the correct way to obtain information about entity connected to
my switch?
Thank you in advance.
Regards,
Giorgio
