I am setting up UDT in our environment and I am having some issues. My user machines are connected to 3750 but the SVI's for user subnets/Vlans are on cisco FWSM. Now where the SVI is configured one a 6509 it pulls out user machine mac address and IP and links to the relevant switchport. However, in case of cisco FWSM it will not show this information. Wondering if any one has face the same problem and knows how to fix it?
