That particular switch does support port mirring, as per the www.cisco.com: Redirection of traffic from any port to a "sniff" port. (Any switching port can be designated as a "sniff" port.) But that would only be a port at a time, so it depends what you want to monitor...even with a tap, is it possible to view all traffic going through and amidst the switch?? i.e. without building 24/48 taps for each connection? (I realize one tap for the uplink, but that would only grab the outgoing/incoming traffic and not the LAN traffic) -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Ulric Eriksson Sent: Friday, March 18, 2005 9:16 AM To: Marc Hering Cc: snort-users () lists sourceforge net Subject: Re: [Snort-users] Span/Snoop ports...

Hey Guys, I just deployed a Snort box to one of our data centers...and I ran into a bit of a snafu. We have a 2948G-L3 switch and want to snort on it. The problem is that a L3 switch doesn't suppprt a snoop port...Has anyone found a way around this?
Depending on the IOS version, you should be able to use the "port monitor" or "monitor session" commands.
