Hello,
I am using a HP 3500yl openflow 1.3 capable sdn switch. I am trying to get
a basic topology working, I have created 2 VLANS one vlan for the
controller and another for the hosts. The second vlan containing the hosts
is driven by the controller.
I have tried running simple_switch and rest_router example scripts with
openflow version set to 1.0 on the switch and everything works as it
should: the flows are being pushed and the hosts can ping each other. But I
need pipeline support, which was only added in openflow 1.3. The
rest_router example with openflow 1.3 doesn't seem to work. On the
contrary, the simple_switch example seems to work on 1.3 as well: I can see
the flows are pushed down to the switch and the hosts can ping each other.
Is any of you aware of running into problems with rest_router running on
openflow 1.3, or anything I could try to make this work?

But when I try to get the rest_router example to work. No flows are pushed
and none of the hosts can ping themselves:

For my experiment, I need to make changes on top of rest_router, hence need
that example to work.
