AFAIK - you cannot configure a SPAN port on a router. Switching based platforms only.

I think the only way you can span or mirror ports is if you have one of the hwic switchcards installed , if if it is just a router port then there is no span option . It is a router and not a layer2/3 switch which has a span function.
