Yes, it is totally possible. The only problem would be if you try to use multiple threads to read/write on one port, in which case you should use multiple queues. Look at l3fwd app for instance. You can use just a single core to handle packets on multiple ports. Pablo > > Is there any reason for this kind of behaviour? > > Thanks! > > Br, > Newman P.
