Interface POS1/0 on Cisco 7204VXR (NPE-G1) IOS ver.12.4(10a)

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

Hardware is Packet over Sonet

Internet address is

MTU 4470 bytes, BW 155000 Kbit, DLY 100 usec,

reliability 255/255, txload 50/255, rxload 17/255

Encapsulation HDLC, crc 32, loopback not set

Keepalive set (10 sec)

Scramble enabled

Last input 00:00:00, output never, output hang never

Last clearing of "show interface" counters 1y7w

Input queue: 0/75/408/475721 (size/max/drops/flushes); Total output drops: 6088583

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

Your counters are over a year old. I would not put much behind these numbers since there is no way to tell when any of this happened. Clear the counters and check in 24 hours to see if the incremented.
