Rate limit subscriber ASR9k BNG

[prague]

Hi everyone ,

I use the policy map below to limit the subscriber, but when I try to use the whole package or when the speed test is at full load on router, I see packet losses. Anyone know the reason?

policy-map 20M
class class-default
police rate 20 mbps burst 3840000 bytes peak-rate 20 mbps peak-burst 7680000 bytes
conform-action transmit
exceed-action drop
!
!
end-policy-map

Thanks

Working with shape. However, when the traffic is 20, the delays (ms) increases, probably due to the shape structure.

On ingress, PPPoE control frames (Ethertype 0x8863) are prioritised, but PPPoE keepalives (Ethertype 0x8864) are not. If the CPE is continuously exceeding the ingress policer rate, it's possible that keepalives will be dropped.
