Actually when I type the command

35550LabCons8#sh mls qos int fa 0/14 statistics
FastEthernet0/14
Ingress
  dscp: incoming no_change classified policed dropped (in bytes)
    0 : 643615174 643615174 0 0 640592964
Others: 2086369444 2086369444 0 0 1761236966
Egress
  dscp: incoming no_change classified policed dropped (in bytes)
    0 : 3016266 n/a n/a 0 0
Others: 258929999 n/a n/a 0 0

It is really showing input drops !

Siva, it is really policing. When I issue no service output test, see the
result,

Subject: Re: 3550 Policing

can you remove that policy and do a show int again (after 30 seconds)
? I just want to make sure it is really policed. You can also show
policy int <id> to see if it is really policed.

anyway, if it is really doing that way, it is probably a bug ..you can
just reload it to see if it fixes it or upgrade to latest version or
open a TAC case for capturing anything needed to fix the problem.

But please do a sanity check as I stated above.

Thanks
Balaji
