Order of Operations: Access lists vs. SPAN

Unanswered Question
Aug 5th, 2008

If I'm monitoring a port on SPAN, will traffic blocked by an access-list on that port still be copied by SPAN to the SPAN Destination port, or does SPAN monitoring take place after firewall filtering?

I have this problem too.
