Yes, the CRS will limit the amount of traffic that is punted to the RP. This is done on the ingress linecard by LPTS.
By increasing the packet size you are most likely hitting the limit.

Hello,
Above result is PING from CRS-1 to another switch, we try to vary packet size and found that if its size greather than 2800 then we always get 4 packets loss from 1000.
Can you please advice?
Thanks,
Rojarek
