I have a 4404 connected to a 3750G. When I ping from the switch to the controller with anything above 250 byte packet I loose pings. The larger the packet the more loss. I am setup with LAG and have the switch configure to only allow the VLAN's needed. I have tried using both copper and fiber GBIC's and still get the same result. I even tried another switch and still drop packets. I factory cleared the 4404 and started over and still dropping packets.
Any suggestions? This condition is keeping the AP's from staying connected to the controller.
