For complete information about creating ACL rules and QoS policies, refer to Access Control Lists (ACLs)
and Quality of Service (QoS).
1. Create a Layer 2 extended ACL for specified protocol traffic.
CONFIGURATION mode
mac access-list extended name permit {arp | frrp | gvrp | isis | lacp | lldp
| stp} cpu-qos
2. Create a Layer 3 extended ACL for specified protocol traffic.
CONFIGURATION mode
ip access-list extended name permit {bgp | dhcp | dhcp-relay | ftp | icmp |
igmp | msdp | ntp | ospf | pim | rip | ssh | telnet | vrrp} cpu-qos
3. Create an IPv6 ACL for specified protocol traffic.
CONFIGURATION mode
ipv6 access-list name permit {bgp | icmp | icmp-nd-na | icmp-nd-ns | icmp-
rd-ra | icmp-rd-rs | ospf | vrrp} cpu-qos
4. Create a QoS input policy to rate limit input traffic.
CONFIGURATION mode
qos-policy-input name rate-police [rate-kbps] [burst-kbytes] peak [rate-
kbps] [burst-kbytes] cpu-qos
5. Create a QoS class map to filter protocol traffic.
CONFIGURATION mode
class-map match-any name match {ip | mac | ipv6} access-group name cpu-qos
6. Create a QoS input-policy map to associate filtered protocol traffic with the rate limiting
configuration.
CONFIGURATION mode
policy-map-input name class-map name qos-policy name cpu-qos
7. Enter Control Plane configuration mode.
CONFIGURATION mode
control-plane-cpuqos
8. Apply the QoS input policy-map that configures rate limiting on specified protocol traffic on the
control plane.
CONTROL-PLANE mode
service-policy rate-limit-protocols input-policy-map cpu-qos
