I try to pass metadata to the controller through the following flow:
ovs-ofctl add-flow br-int "in_port=5 priority=2 actions=set_field:123->
metadata,controller(reason=no_match)"
I do see the following flow when I do dump-flows:
cookie=0x0, duration=310.921s, table=0, n_packets=0, n_bytes=0,
idle_age=310, priority=2,in_port=5 actions=load:0x7b->OXM_OF_METADATA
[],controller(reason=no_match)
But when I check in the controller side I see metadata=0.
I check the metadata value with 2 different methods:
1. By snooping the communication between switch to controller and see
metadata=0.
2. By using the extract_flow function inside the controller to retrieve
the flow
corresponding to the packet_in message.
What am I doing wrong here?
Thanks,
