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-transmit policer keyword.

• PFC QoS does not support the set-dscp-transmit or set-prec-transmit keywords as arguments to

the exceed-action keyword.

• 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:

Configuring a Per-Interface Policer

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

Command Purpose

Router(config-pmap-c)# police aggregate

aggregate_name

Configures the policy map class to use a previously defined

named aggregate policer.

Router(config-pmap-c)# no police aggregate

aggregate_name

Clears use of the named aggregate policer.

Command Purpose

Router(config-pmap-c)# police [flow [mask {src-only |

dest-only | full-flow}]] bits_per_second

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}]

Creates a per-interface policer and configures the policy-map

class to use it.

Router(config-pmap-c)# no police [flow [mask

{src-only | dest-only | full-flow}]] bits_per_second
