Hi,

Duplex mismatch are common cause of drop packets when pinging a host. Although there are documentations that vendors (including Cisco) recommends leaving the settings to Auto/Auto, experience dictates to harcode the speed and duplex to say 100Mbps/FullDuplex specially for the following: Router, Firewall, Switch, and Server. To find the segment that causing the packet drops, you can execute "show interface interface_name_number" and look for drop packet, errors, and collissions.

Other cause of drop packets;

- Faulty cabling

- Congestion

- Faulty NIC

- Routing loop

- Network device has high CPU/MEM util (probably under DDOS attack)

- Harmonics

Regards,

Dandy
