thank you for your response. but what did you mean hitting 0? that's mean click on zero on my PC, or what ?

Hi Munir,

Are they increasing? If not you can clear them and monitor moving forward. As EtherMAN mentioned you ideally want the packet drops to be at zero but sometimes these counters will increase overtime and typically not an amount that is detrimental to the network. They almost always increase because of over utilizing bandwidth on a port. Hitting the "0" (Zero) key while the output is present will clear all the counters.

Hope this helps.

Remember this is ethernet ... The way we use this command is looking for micro-bursts of max interface traffic that overruns an single interface thus creating congestion and packet drops... in the perfect world all ports should be ZERO.... any port that has counters going up on it is dropping frames and being over run ....
