RE: port mirroring for two targets

[Luis Lopez Sanchez <luis.lopez () atosorigin com>]

Hi IDS-ers,

For more understanding for using taps and span/mirroring ports in low cost switching infrastructure, see this very 
interesants links from TaoSecurity Blog:

http://taosecurity.blogspot.com/2005/12/taps-and-hubs-part-deux-yesterday-i.html

Note: In standard network infrastructure, such as Enterasys or Cisco is normally possible to use several ports to span 
even remote-span. In low cost or old switches is not possible.

Have luck!

Regards,

It depends on the make and model of the device you're trying to create
the mirrored port on.  Some devices don't allow you to create more
than one mirrored interface for a particular port.

You may also want to look at getting a network tap which would
probably allow you to monitor a particular interface with multiple
sensors.

Hope this helps.
