Hi,
In ofp_phy_port data structure, that includes per port info, there is a
hw_addr field, which I always assumed is the MAC address of the port, is
this something different?

Hi Sriram,
I don't think there is any mapping to switch port MACs on the controller
by default. You'd probably have to do something like what you described.
But why do you need the MAC addresses of the switch ports in order to
setup flows?
(Or did I misunderstand you and you referring to the MAC addresses of H1
and H2?)

Hello All,
I have the following topology setup
H1-S1-S2...-Sn-H2 (n varies from 1 to 20 in my testbed).
I need to pre-install set of flows in each switch (when I receive a
Datapath Join Event). To achieve this i need to know the MAC address
of the connected interfaces in the switches.
I was thinking to send an ARP request from the controller to all
switches when I receive the datapath_join_event and the switch can
FLOOD the request to all connected ports. With the ARP reply I can
determine the MAC addresses.
However I would like to know if there is a better way to get this
information (dynamically determine the MAC addresses of all
connected switch links). Is there an API which gives this
information already?
Thanks for your help
Sriram
