snort with 2 nics - collecting only UDP data

["Tinu Patel" <tinu.patel () insignis com>]

Hi folks....
 
I am pretty new to snort...so this may be a dumb question but here
goes...
 
I have a snort box that has 2 sensors running on 2 different nic's. 
One of the nic's is capturing data outside the firewall and is working 
perfectly fine.  The other nic is capturing data inside the firewall 
from a monitor port on an HP switch (where we forwarded all switch 
traffic to).  The internal sensor is only picking up UDP data... and a 
TON of it.  It doubled the database size and then some in one night 
just from garbage sensor reports.
 
Why is it not picking any TCP traffic?  Am I doing something wrong here?

 
My snort.conf has:
 
log tcp any any -> x.x.x.x/x any any 
 
Thanks
