 I wouldn't do that.  You'll run into layer 2 loop issues I'm thinking.
You'll see some especially nasty stuff if you have spanning tree on.

Subject: Port mirroring across multiple switches


What's the best approach to port mirror traffic from multiple switches?
Should I enable mirroring on one port of each switch, and then connect
those ports to a hub and put my sniffer on the same hub? 

My ultimate objective is to collect ARP query information from all
switches. 

Thanks.
