Hi Fujita,
Thank you so much for the response.
What I am trying to achieve is incrementally pass flow with the combination
of matches. For Example, I first pass a flow with match on ethertype, next
with match on ethertype and source MAC, then with match on ethertype,
source MAC and destination MAC, and so on. I have added this small snipet
of code below:
while (count < 7):
match = parser.OFPMatch(in_port=5097) ----> (creating here)
if (count & 1):
#match = parser.OFPMatch(in_port=5097, vlan_vid=vlan)
match.vlan_vid=vlan -----> (modifying here)
print 'match on vlan = ',vlan
if (count & 2):
#match = parser.OFPMatch(in_port=5097, eth_src=src)
match.eth_src=src
print 'match on Source MAC Address', src
if (count & 4):
#match = parser.OFPMatch(in_port=5097, eth_dst=dst)
match.eth_dst=dst
print 'match on Destination MAC Address', dst
actions = [parser.OFPActionOutput(out_port)]
print 'Flow to be added'
self.add_flow(datapath, 1000, match, actions, table_id)
time.sleep(2)
count+=1
This code only pushes match on in_port=5097 and action as out_port. Is
there no way I can modify the match fields on the object once I have
created other than by passing as parameter to parser.OFPMatch()? It would
be great if you could point out a way of modifying the match object in the
code above. I am sorry if I am ignoring something very obvious.
