After upgrade to release 10.4.2, the policy configuration appears as follows:
policy-map type control-plane test
!
class test_Remapped_0
set qos-group 0
police cir 300 pir 300

class test_Remapped_5
set qos-group 5

In release 10.4.2, ARP_REQ is mapped to queue 6, ICMPV6_RS and ICMPV6_NS are mapped to queue 5, and ISCSI is
mapped to queue 0.
By default, CoPP traffic towards the CPU is classified into different queues as shown below.

The following table lists the CoPP protocol mappings to queues, and default rate limits and buffer sizes on the S4148FE-ON platform. The
number of control-plane queues is dependent on the hardware platform.
