Good evening I should compare with you about packets loss on interface POS as in subject title, below there's output of #show interface:

c7200-B#sh interface POS1/0

POS1/0 is up, line protocol is up

Have you any idea?

At this moment I had ask an analysis over the link at my carrier.

Could you suggest me IOS command to verify that i don't have hw problem on POS interface, or any configuration problem?

Any information that you can send me are welcomed.

Best Regards
