Customer packet drops issue

Hi,

Our customer took 30Mbps metro link from us. Even at 17Mbps link utilization they are facing packet drops. Our side policer is implemented for 30Mbps. There are no errors on customer or our interfaces. But I can see exceed packets under 'show policy-map interface' . Used maximum Bc. Does customer required to implement shaping his end with same CIR and Bc.

Regards

Re: Customer packet drops issue

Hi Siva,

It is not a mandatory rule that Customer should also have the same CIR configured with shaping.

When Customer have 30 Mbps circuit SLA with Service Provider, he may be able to pump ta line rate from CE side. But on PE side, it will be policied and excess traffic will be dropped.

To avoid Customer's traffic getting dropped at PE, It is advisible to configure shaping at CE side so that the traffic SLA will be maintained without or with less number of packet loss.

Can you post your config and show policy-map interface output with traffic?.

Nagendra
