Hi all
What is the expected/standard way to handle error messages to flow_mod
requests?
If they are treated as SYNC messages, then my application would have to wait for
an ack. But if the switch has happily accepted the flow_mod, it does not send
back anything - causing my app to hang forever.
Hi,
The choice is yours.
To do a synchronous call, send the flow_mod followed up a
barrier_request. You will get the barrier_reply back.
To do asynchronous calls, just send the flow_mod and wait for error
messages. The error messages should carry the same xid (transaction
id) as the flow_mod
