Unicast UDP traffic showing up on incorrect ports

Hi,

I have a Cisco 3560G that has an ip of 192.168.1.1 on Vlan 1 and a secondary interface of 192.168.10.1 on vlan 1 as well.  I was doing some traffic analysis and noticed that I was getting Unicast UDP traffic showing up in my trace even though the MAC or IP of the Source or destination did not reside out the port I was monitoring, or the port I was monitoring from. 

One article I read

http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00801d0808.shtml#cause3

Indicates this could be an overloaded Switching table but I checked my MAC tables and I have a grand total of 265 MAC address entries when I run the show mac-address-table count command and it indicates there are 5295 entries in Total Mac Address Space Available.

Does anyone have any ideas on this?

Thanks,

William Sixsmith
