The following display is an abbreviated output from the command, show interface Ethernet 1/1.  Two packet drop counters appear under the counters reading the logical interface information. Conditions that may cause these counters to increment are explained below:

show interface ethernet1/1

-------------------------------------------------------------------------------

Name: ethernet1/1, ID: 17
Link status:

Runtime link speed/duplex/state: 1000/full/up

  Configured link speed/duplex/state: 1000/full/auto

MAC address:

  Port MAC address 00:1b:17:0b:80:11

Operation mode: virtual-wire

-------------------------------------------------------------------------------

Logical interface counters read from CPU:

-------------------------------------------------------------------------------

bytes received                           675651250

bytes transmitted                        523417297

packets received                         916417  

packets transmitted                      816119  

receive errors                           0       

packets dropped                          0        

packets dropped by flow state check      55

packets dropped by flow state check: This counter is incremented for packets matching flows which are either in expired/inactive/discard states and have not been removed by age-out process.

packets dropped: This counter is indicative of several conditions such as receiving the multicast packets on the same interface, dropping non-ip packets (other than ARP),  no topology is configured, a session setup failure, or a discarded route is found.
