we configured the SPAN in the 3560 switch:
monitor session 1 source int g0/2
monitor session 1 destination interface Gi0/12
and we have sniffer software install on the Laptop and connect to interface g0/12.
can i say, for ALL the traffic coming in and out from port g0/2 to send to g0/12?
our port g0/2 connect to firewall, how come we cannot sniffer some traffic?
