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. -Tim -----Original Message----- From: Hasnain Atique [mailto:hatique () hasnains com] Sent: Thursday, December 04, 2003 4:23 AM To: security-basics () securityfocus com 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. -- H --------------------------------------------------------------------------- ---------------------------------------------------------------------------- --------------------------------------------------------------------------- ----------------------------------------------------------------------------
