Without getting too detailed, I have a 6509 with a 48port 10/100/1000 GigE card installed. 7 ports have major ping and comms drops to them daily from 10:00am to 11:00am. Through all troubleshooting and cable swapping, etc... the trouble has remained with the ports and has not been specific to any piece of equipment, IP or VLAN... just the 7 ports that drop major pings daily between 10:00 - 11:00am. Anybody ever run across one like this? Seems like a timer is expiring somewhere.. and it is central to the router... But WHAT??
