Cisco Systems OL-4266-08 Configuring Policy Map Class Policing, Using a Named Aggregate Policer

Chapter 42 Configuring PFC QoS

Configuring PFC QoS

Configuring Policy Map Class Policing

When you configure policy map class policing, note the following information:

•PFC QoS does not support the set-qos-transmitpolicer keyword.

•PFC QoS does not support the set-dscp-transmitor set-prec-transmitkeywords as arguments to the exceed-actionkeyword.

•PFC QoS does not detect the use of unsupported keywords until you attach a policy map to an interface.

These sections describe configuration of policy map class policing:

•Using a Named Aggregate Policer, page 42-76

•Configuring a Per-Interface Policer, page 42-76

Note Policing with the conform-action transmit keywords sets the port trust state of matched traffic to trust DSCP or to the trust state configured by a trust command in the policy map class.

Using a Named Aggregate Policer

To use a named aggregate policer, perform this task:

Command	Purpose
Router(config-pmap-c)# police aggregate	Configures the policy map class to use a previously defined
aggregate_name	named aggregate policer.
Router(config-pmap-c)# no police aggregate	Clears use of the named aggregate policer.
aggregate_name

Configuring a Per-Interface Policer

To configure a per-interface policer, perform this task:

Command	Purpose
Router(config-pmap-c)# police [flow [mask {src-only	Creates a per-interface policer and configures the policy-map
dest-only full-flow}]]bits_per_second	class to use it.
normal_burst_bytes [maximum_burst_bytes] [pir
peak_rate_bps] [[[conform-action {drop
set-dscp-transmit dscp_value set-prec-transmit
ip_precedence_value transmit}] exceed-action {drop
policed-dscp transmit}] violate-action {drop
policed-dscp transmit}]
Router(config-pmap-c)# no police [flow [mask	Deletes the per-interface policer from the policy-map class.
{src-only dest-only full-flow}]]bits_per_second

set-dscp-transmit dscp_value set-prec-transmit
ip_precedence_value transmit}] exceed-action {drop
policed-dscp transmit}] violate-action {drop
policed-dscp transmit}]
