Hi all,
I am starting with openFlow and nox. As starting example I am trying to
understand the pyswitch code. However, there are some lines of code that
are not very clear to me. Those lines are :
1- if ord(srcaddr[0]) 1: what is really meant by this condition ?
2- dst[0] != inport: why
Hi,
I am a little bit confused about the inport parameter in :
* send_openflow(dpid, bufid, buf, openflow.OFPP_FLOOD, inport)
And in:
* install_datapath_flow(dpid, flow, 5, 0, actions, bufid,
openflow.OFP_DEFAULT_PRIORITY, inport, packet)
Do they design the port of communication between the
Thanks Kyriakos :)
In fact, my confusion came from the fact that the inport is got from
registering to the packet_in event. So when you register you get the
inport, however this inport is used for two different cases.
So, in the case where the inport is got from registering to the
packet_in
Hi all,
I have some problem to understand some conditions in the nox example
'pyswitch'.
*My first question is that when a packet_in_event is received by the
controller, the 'inport' parameter designs the port of controller that
received the packet from the switch or the port of the switch
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
this in the definition of
install_datapath_flow()

I am trying to retrieve the topology of an openflow network through

Hi all,
I am trying to use the authenticator component, however it seems to be
not fully supported by python. In fact, I get the following error:

Is there any method to have this event converted to python.

Hi,
When executing the method 'get_names_by_mac()' of py_bindings I get the
following output, which seems a little bit strange :

Can you please telle what does this mean ?
Thanks for your help.

Karim

Did you add pyauthenticator as a dependency for your component (though I don't
think this would cause exactly that error)?
Hi Murphy,
In fact, it was a dependency problem :)

Hi all,
When trying my controller I noticed some strange behaviour.
In fact, my aim is to set a path from one host to another. I started
doing this by setting it statically. Than I enhanced it using the
routing module to calculate the optimal path. However, when the enhanced

that acts like an L2 learning switch. When it reconnects to its controller,
it will stop doing this again.

Is there any function in nox that allows to select the fields to match
in a flow table (e.g. order the switch to ignore the destination mac
address).
Thanks a lot.

I am developing an application to reroute traffic upon a link failure,
