We had remote-span working without at issue, and we were able to play traffic to both test machines without altering our traffic samples. The switches were unable to cope with this level of broadcast traffic and so throughput was worse than with RSPAN.

This example shows how to set up a SPAN session session 1 for monitoring source port traffic to a destination port.

Why would the install change from the physical to the virtual ones? SPAN mirrors receive or transmit or both traffic on one or more source ports to a destination port for analysis.

LB is route based on originating virtual port scenario: I guess we will have to wait and see if that means combo-feature-cards like the Intel x or just "pure ISCSI" cards as it is now.
