I have setup snort on my local LAN. The snort box is collecting only from
my LAN.
I want to sniff all packages that came from my WAN in to the LAN using
My question is that if I span the Ethernet port of my WAN router to the
sniffer port should collect all  WAN data coming in the LAN?
Here is my network:

     switch CAT4k
     Snort box

Do I need any special configuration on the snort box to use the span
command from the switch?

Thanks for the support,
