LB1120 ARP Flooding

[timbash]

I  have several LB1120s and on my network I have two IP ranges.  The LB1120 is set to 192.168.3.XX and the other network is 192.168.1.XX.  

The LB1120 fills up the ARP cache i almost immediately with its own mac address in the 192.168.1.XX subnet before the actual devices on the network even have a chance to respond.  

How do I stop this from happening.  I need to perform network scans to confirm which IP addresses are actually active.

Still having this problem and no repsonses.  I believe this is a hardware problem.

Anybody?
