Control Plane Policing Commands
This chapter is a reference for the Control Plane Policing (CoPP) commands.
clear interface cpu counters
Use this command to clear the CPU queue counters.
Command Syntax
clear interface cpu counters
Parameter
None
Command Mode
Exec mode and Privileged Exec mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#clear interface cpu counters
cpu-queue
Use this command to set protocol queues shaper and enable/disable queue monitoring for drop.
Command Syntax
cpu-queue (acl|arp|best-effort|bgp|bpdu|ccm|dhcp|daivm|igmp|ipmc-miss|isis|l3-miss|mpls|nd|ospf|pim|ptp|rip|sflow|bfd| vrrp|vxlan) (lossy | lossless|) (monitor|no-monitor|) (rate <0-100000>|)
no cpu-queue (acl|arp|best-effort|bgp|bpdu|ccm|dhcp|daivm|igmp|ipmc-miss|isis|l3-miss|mpls|nd|ospf|pim|ptp|rip|sflow|bfd| vrrp|vxlan) (lossy | lossless|) (monitor|no-monitor|) (rate <0-100000>|)
Parameters
acl
ACL queue parameters (for acl logging)
arp
ARP queue parameters
best-effort
Best-effort queue parameters
bfd
BFD queue parameters
bgp
BGP queue parameters
bpdu
BPDU queue parameters
ccm
CCM queue parameters
dhcp
DHCP queue parameters
igmp
IGMP queue parameters
ipmc-miss
IPMC-Miss queue parameters
isis

monitor
Monitor CPU queue usage
no-monitor
Do not monitor CPU queue usage
lossless
Configure cpu queue as lossless
lossy
Configure cpu queue as lossy
rate
Set CPU queue rate <0-100000>
Default
CPU queues are set with the default values as shown in
Table 2-1.
Command Mode
Exec mode and Privileged exec mode
Applicability
This command was introduced before OcNOS version 1.3.8.
Example
Use the following command to configure rate/monitor/no-monitor for protocol queues:
#configure terminal
#cpu-queue bpdu rate 500 lossy no-monitor
Use the following command to verify the rate received on each protocol queue:
#show int cpu counters rate kbps
Load interval: 30 second
+-------------------+--------------+-------------+--------------+-------------+
| CPU Queue(%) | Rx kbps | Rx pps | Tx kbps | Tx pps |
+-------------------+--------------+-------------+--------------+-------------+
bpdu ( 0%) - - 0.54 1
Use the following command to verify the maximum, configured, and default configuration values:
#show cpu-queue details
Cpu queue Rate In PPS Monitor Status Lossy Status
Name Configured Default Max Rate Allowed Configured Default Configured Default
