Configuring a Control Plane Policy Map
You must configure a policy map for CoPP, which includes policing parameters. If you do not configure a
policer for a class, the following default is configured:
• 50 packets per second (pps) with a burst of 32 packets (for Cisco Nexus 9300 and 9500 Series and 3164Q,
31128PQ, 3232C, and 3264Q switches)
• 150 kilobits per second (kbps) with a burst of 32,000 bytes (for Cisco Nexus 9200 Series switches)
Before you begin
Ensure that you have configured a control plane class map.

DETAILED STEPS
Purpose
Command or Action
Enters global configuration mode.
configure terminal
Example:
Step 1
switch# configure terminal
switch(config)#
Specifies a control plane policy map and enters policy map
configuration mode. The policy map name can have a
maximum of 64 characters and is case sensitive.
policy-map type control-plane policy-map-name
Example:
switch(config)# policy-map type control-plane
ClassMapA
switch(config-pmap)#
Step 2
Specifies a control plane class map name or the class
default and enters control plane class configuration mode.
class
{
class-map-name
[
insert-before class-map-name2
]
|
class-default
}
Step 3
