Is there a Sniffer port or a Port mirror on a 2948-L3

I want to plug my sniffer into my 2948-L3 switch. Is there a way to mirror the port that connect to my firewall to the port where my Sniffers is connected. I know that I can use a cheap generic ethernet hub to make this work but I am hoping that there is a trick to do this with the configuration. Please comment. Thanks.

The 2948G-L3 is a switch-router. As such they don't support spanning/port mirroring. As per: http://www.cisco.com/warp/public/473/41.html#l3

The only way to do so is as you posted (place a hub/switch on that port).
