Re: Emulate Switch for L2 Network Security Testing

[Phillip Ames <pentest () una-cerveza com>]

Hi,
You may be able to use Dynamips/Dynagen to accomplish what you need. 
You can create virtual switches that have ports assigned to different 
VLANs, however, if I recall correctly you can't telnet to those switches 
and manage them the way you can manage a "real" network switch.  You can 
only do that for L3 devices that you provide an IOS image for.

Dynamips also provides a good method for capturing packets on the 
simulated devices interfaces for later analysis.

HTH,
-Phil
