bridge detection

Subject: bridge detection
Date: Sat, 25 Dec 2004 11:29:48 -0500 (EST)

hi,
   I was wondering are there any programs which can detect switches/routers, 
based as well on linux.
   The problem is that one company is setting up large LAN, with internet 
access, based on static ip/mac address, for paying reasons. Many clients 
seperate their connection, often giving mac of the bridge not the PC.
   i had many ideas about that, eg. checking the vendor for the mac, signal 
replays from the source.
i worry also about 'clear' switches, non programmable ones.

  Could please someone give me some advise?

sorry for my bad english.
