ICMPv6-RS-NS is mapped to queue 5
iSCSI is mapped to queue 0
The rate limit configuration in CoPP policy before upgrade is automatically remapped to queues 6, 5, and 0
respectively after upgrade.
For example, in release 10.4.1, the following policy configuration is applied on queue 5, which in 10.4.1 is mapped to
ARP_REQ, ICMPV6_RS, ICMPV6_NS, and ISCSI protocols:
policy-map type control-plane test
!
class test
set qos-group 5
police cir 300 pir 300
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
police cir 300 pir 300
!
class test_Remapped_6
set qos-group 6
police cir 300 pir 300
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.
