You can set the port to accept incoming packets by issuing the following
command:
set span x/x x/x inpkts enable
but there are some considerations that have to be made depending on your
architecture. Please see

pan.htm (watch the wrap) for much more information. I hope that this helps!

also remember that the the port that you are spanning to (the one with the
snffer) cannot be used as a regular network port anymore. Spanning disables
that ability and it can only be used to watch the spanned packets.
So you can't test for things on the sniffer PC.
