Dears,
Can I force (Packet-In) to send instructions to a specific switch without any
request from the switches ?.
For instance, I intend to create a component which sends a dictionary contains
{Source, Destination, In_port, data path_id} or assigning a value.
src = rdata[1] # 00:00:00:00:00:01
dst = rdata[2] # 00:00:00:00:00:04
dpid = 256
in_port = 1
#self.logger.info("packet in %s %s %s %s", dpid, src, dst,
in_port)
# learn a mac address to avoid FLOOD next time.
self.mac_to_port[dpid][src] = in_port
but I got the next error
Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 763, in run
self.__target(*self.__args, **self.__kwargs)
File "/home/mininet/ryu/ryu/app/C1.py", line 199, in foo
self.mac_to_port[dpid][src] = in_port
KeyError: 256
your help would be highly appreciated.
Best Regards
A. Soliman
