Hi
I want to add a data flow with priority 1, and after passing 5 seconds I want
to change its priority to 10. I have used the following code to implement this
concept. But, it is not working :)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
match = parser.OFPMatch(eth_src='01:00:00:00:01:00',
eth_dst='02:00:00:00:02:00')
actions = [parser.OFPActionOutput(2)]
priority1 = 1
command=ofproto.OFPFC_ADD
inst = [parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS, actions)]
self.add_flow(datapath, command, priority1, match, inst)
time.sleep(5)
flow_del = parser.OFPFlowMod(datapath=datapath, priority=10, match=match,
command=ofproto.OFPFC_MODIFY, buffer_id= ofproto.OFP_NO_BUFFER,
instructions=inst)
datapath.send_msg(flow_del)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
would you please show me the way to do it?
Please note that as far as I know that the priority changing is not possible
by using the "OPFActionsetfield" option. Because priority is not supported by
the "OFPMatch".
Thanks in advance.
