Queue-based Control Plane PolicingWhen configuring a queue-based CoPP policy, take into account that there are twenty-one CP queuesdivided into groups of 7 queues for the Route Processor, Control Processor, and line-card CPUs:• Queues 0 to 6 process packets destined to the Control Processor CPU.• Queues 7 to 13 process packets destined to the Route Processor CPU.• Queues 14 to 20 process packets destined to the line-card CPU.Dell#show mac protocol-queue-mappingProtocol Destination Mac EtherType Queue EgPort Rate (kbps)-------- --------------- --------- ----- -----------------ARP any 0x0806 Q1/Q8/Q2/Q9 CP/RP 100FRRP 01:01:e8:00:00:10/11 any Q19 LP 300LACP 01:80:c2:00:00:02 0x8809 Q13 RP 500LLDP any 0x88cc Q6 CP 500GVRP 01:80:c2:00:00:21 any Q12 RP 200STP 01:80:c2:00:00:00 any Q13 RP 150ISIS 01:80:c2:00:00:14/15 any Q13 RP 50009:00:2b:00:00:04/05 any Q13 RP 500The protocols mapped to each CPU queue and the default rate limit applied to the 7 CPU queues for theRoute Processor, Control Processor, and line cards are as follows.Table 11.
