Troubleshooting a Dropped Packets Alert
Dropped packets, or queue drops, may indicate buffer depletion. Input queue drops typically occur when a packet is process-switched. A process switch means that the router cannot use a preferable route-cache method, such as fast switching or Cisco Express Forwarding (CEF), to handle the forwarding decision. If input drops are still present, it implies that there is simply too much traffic. Output drops are caused by a congested interface.
