If you create a mirror port and plug in any IPS/IDS, it will see the
traffic. TippingPoint, ISS, etc. All can do that.
Also, pretty much any decent managed switch can have mirror ports. This
is not unique to Cisco.
Keep in mind, you cannot do real-time IPS (intrusion prevention) in any
reliable manner this way. You have to be IN-LINE to do real-time
blocking and filtering. Passive monitoring off a mirror port only allows
you to send RSTs to stop stuff, and that is not a very reliable way to
block bad stuff.

Subject: IPS and Trunking
Cisco has a great feature where I can configure all traffic on a switch
to go to a trunk port, plug in the IPS/IDS to the trunk port and see all
traffic. Can other vendors, such as Sourcefire, TippingPoint, ISS do
this?
Thanks,
