Snort and switches??

["Edward Marshall" <edtech () tstt net tt>]

Thanks guys, for suggesting some good log analyzer for snort 2.0 /2.0.1
(Acid, barnyard, etc). A problem I am presently experiencing is that
there is this company that has all their servers and end-user PCs
connected directly to a series of switches (not Cisco). When I connect
the Snort machine (Mandrake 9.1/ Snort 2.0.1) to the switch, it is not
picking up all the network traffic.
 
For example, when I run superscan on the network, snort does not log any
activity into the scan.log or portscan.log files. But if I take that
same snort machine and connect it to a 3com hub and connect a few other
PCs to that same 3com hub as well and run superscan (on one of those
PCs), snort will log all the superscan activity into the portscan.log
and scan.log files. 
 
Does anyone have any suggestions or solutions as to how snort can detect
all network traffic when connected to a switch??
