He noted that some NIC's still process the packet but just pass it back to the driver rather than the wire... He wants to prove that it doesn't even hit the NIC. Will snoop detect all traffic to/from the card ?Snoop uses DLPI loopback to read the packets. How it works depends on the driver implementation (somewhat), but basically you get a copy of every packet that the upper level (such as IP) sends and a copy of every packet received on the wire. It's not necessarily enforced that every packet you see via DLPI loopback is in fact transmitted -- some might not be -- but the ones that you don't see aren't sent.
global zone to prove the case.
Essentially he wants to be able to assure his users that the transfers
will be fast and not affect the network users. If they complain that
during these operations are slow, then he wanted to recommend sharing
a lofs mount and share the data that way (and also be assured that it
won't affect the users coming in via the network).
