How to capture Catalyst traffic

Hello friends.

I want to capture all traffic in my net. I have a 5 switch stack of Cisco 3750 Catalyst.

How can I do it?.

Thanks.

You can use SPAN session - traffic from all ports (VLANs) can be mirrored to one port

check following link

Very good link but I want another solution more easy for me if it can be possible.

Since these are switches, you will have to span the ports in order to capture the traffic.

I discovered that I can configure span ports with Cisco Network Assistant

I open a span session in a port of one of my stack switches.

What I must to configure encapsulation: native o replicate?. Must I to choose any vlan?

Wht I must to do after?.
