Default Queue Mapping Policy
By default, CoPP provides 27 CPU queues for data forwarding that would have a default scheduling weight. The system pre-defines 16 types of control plane protocols mapping from queue 8 to 26. The default queue mapping policy is as follows.
Table 1. Default Queue Mapping Policy
Protocols | CPU Queue | Default Scheduling Weight |
| RIPng | 26 | 16 |
| ERPS | 25 | 32 |
| MVRP | 24 | 32 |
SSH/SNMP/NTP/TACACS/RADIUS | 23 | 12 |
BPDU | 22 | 32 |
LACP | 21 | 32 |
LLDP | 20 | 32 |
ARP | 19 | 32 |

OSPF | 13 | 16 |
RIP | 12 | 16 |
DHCP | 11 | 16 |
VRRP | 10 | 16 |

Default* | 0 | 0 |
Reserved: Reserved CPU queues indicate the CPU queues that have not been used by the system pre-defined queue mapping settings. For user-defined CoPP policy, it is recommended to use the reserved queues for queue mapping settings.
Default*: The flow of traffic directed to switch CPU will be sent to CPU queue 0 when the traffic matches no firewall filter rule.
But for the packet with an Inet Precedence or DSCP value, it will not always be sent to CPU queue 0 when the traffic matches no firewall filter rule. When you configure the classifier to classify services on different inbound interfaces by using set class-of-service classifier trust-mode dscp and set class-of-service interface classifier commands. The packets will be sent to the CPU queue according to the Inet Precedence or DSCP value. Mappings from Inet Precedence/DSCP value to CPU Queue are shown in the following tables.
Table 2. Mapping from Inet Precedence value to CPU Queue
Inet-precedence | CPU Queue |
0 | 0 |
1 | 1 |
2 | 2 |
3 | 3 |
4 | 4 |
5 | 5 |
6 | 6 |
7 | 7 |
Table 3. Mapping from DSCP value to CPU Queue
DSCP | CPU Queue |
0,1,2,3,4,5,6,7 | 0 |
8,9,10,11,12,13,14,15 | 1 |
16,17,18,19,20,21,22,23 | 2 |

Default CLI Settings
PicOS will startup with the following CLI commands by default. Users can change the pre-defined CoPP policies but are NOT allowed to delete them.
NOTE: The values of min-bandwidth-pps and max-bandwidth-pps are different on different platforms.
