The issue what you are seeing might be unicast flooding on the switch.
You can read up on unicast flooding caused by assymetric routing here:Asymmetric Routing and HSRP (Excessive Flooding of Unicast Traffic in Network with Routers That Run HSRP)http://www.cisco.com/en/US/customer/tech/tk648/tk362/technologies_tech_note09186a0080094afd.shtml#t8 To combat this issue, you will need to configure the ARP timeout value less than the CAM aging time. eg. Router(config)#int vlan 2Router(config-if)#arp timeout 240 HTH,Cheers,-amit singh
