Chapter 51 Configuring Control Plane Policing and Layer 2 Control Packet QoS
Policing IPv6 Control Traffic
Switch(config)# ipv6 access-list pimv6
Switch(config-ipv6-acl)# permit ipv6 any host ff02::d
Switch(config-ipv6-acl)# exit
Switch(config)# class-map pimv6Class
Switch(config-cmap)# match access-group name pimv6
Switch(config-cmap)# exit
The following example shows how to configure a traffic class to identify MLD protocol control packets:
Switch(config)# ipv6 access-list mldv1
Switch(config-ipv6-acl)# permit icmp any any mld-query
Switch(config-ipv6-acl)# permit icmp any any mld-report
Switch(config-ipv6-acl)# permit icmp any any mld-reduction
Switch(config-ipv6-acl)# exit
Switch(config)# class-map mldClass
Switch(config-cmap)# match access-group name mldv1
Switch(config-cmap)# exit
The following example shows how to configure a QoS policy to police OSPFv6, PIMv6 and MLD traffic
classes:
Switch(config)# policy-map v6_control_packet_policy
Switch(config-pmap)# class mldClass
Switch(config-pmap-c)# police 32k
Switch(config-pmap-c-police)# class ospfv6Class
Switch(config-pmap-c)# police 32k
Switch(config-pmap-c)# class pimv6Class
Switch(config-pmap-c)# police 32k
Switch(config-pmap-c-police)# exit
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# exit
Switch# show policy-map
Policy Map v6_control_packet_policy
Class mldClass
police cir 32000 bc 1500
conform-action transmit
exceed-action drop
Class ospfv6Class
police cir 32000 bc 1500
conform-action transmit
exceed-action drop
Class pimv6class
police cir 32000 bc 1500
conform-action transmit
exceed-action drop
The following example shows how to policy to interface gi2/2 in the input direction:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gi2/2
Switch(config-if)# service-policy in v6_control_packet_policy
Switch(config-if)# exit
