Hi all, I'm trying to register for a error event handler in the following way:
----
def install(self):
self.register_for_error(self.error_callback)
----
I wrote the following handler for error events:
----
def error_callback(self, dpid, type, code, data, xid):
log.debug("Error callback!")
----
When I check the communication between my switch (Pronto 3290) and my NOX
controller with Wireshark I see that my switch sends a vendor error message to
the controller but some how the handler code in the handler does not get
executed.
Below you will find the vendor package send by the controller to the switch and
the error package the switch sends back from the switch to the controller:

Does anybody got a idea what is going wrong or have a idea how I can traceback
why the error callback does not get's executed?
I'm happy to provide more details if necessary.

Maikel
