I know they had some packet traces on the website, so I did some 
searching, and at http://www.snort.org/dl/contrib/other_stuff/
there is "sans_handson.tgz" ... If you download that, it has some 
"exercises" with packet dumps (you can run them through snort)
What your want to do is something similar to the following:

/usr/local/bin/snort -d -c /path/to/snort.conf -l ./log -h x.x.x.x/24 -r 
<dump file>

Once this is done, your data will be sitting in ./log directory.  Or you 
can run them through tcpdump. (There is also some TCPDUMP

Again, almost all ID systems have some false positives, the only way to 
FULLY understand them is to investigate them...
You should play/configure snort to your liking(and your networks). After 
that, im positive you will start to LOVE snort.

Hope it Helps
