Configuring PFC QoS

Enabling Egress ACL Support for Remarked DSCP

To enable egress ACL support for remarked DSCP on an ingress interface, perform this task:

 

Command

Purpose

Step 1

 

 

Router(config)# interface {{vlan vlan_ID}

Selects the ingress interface to configure.

 

{type1 slot/port} {port-channelnumber}}

 

Step 2

 

 

Router(config-if)#platform ip features

Enables egress ACL support for remarked DSCP on the

 

sequential [access-group IP_acl_name_or_number]

ingress interface.

 

Router(config-if)#no platform ip features

Disables egress ACL support for remarked DSCP on the

 

sequential [access-group IP_acl_name_or_number]

ingress interface.

Step 3

 

 

Router(config-if)# end

Exits configuration mode.

Step 4

 

 

Router# show running-config interface

Verifies the configuration.

 

({type1 slot/port} {port-channelnumber}}

 

1.type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

When configuring egress ACL support for remarked DSCP on an ingress interface, note the following information:

•To enable egress ACL support for remarked DSCP only for the traffic filtered by a specific standard, extended named, or extended numbered IP ACL, enter the IP ACL name or number.

•If you do not enter an IP ACL name or number, egress ACL support for remarked DSCP is enabled for all IP ingress IP traffic on the interface.

This example shows how to enable egress ACL support for remarked DSCP on Fast Ethernet port 5/36:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# interface fastethernet 5/36

Router(config-if)#platform ip features sequential

Router(config-if)# end

Creating Named Aggregate Policers

To create a named aggregate policer, perform this task:

Command

Purpose

 

 

Router(config)# mls qos aggregate-policer

Creates a named aggregate policer.

policer_name bits_per_second normal_burst_bytes

 

[maximum_burst_bytes] [pir peak_rate_bps]

 

[[[conform-action {drop set-dscp-transmit1

 

dscp_value set-prec-transmit1ip_precedence_value

 

transmit}] exceed-action {drop policed-dscp

 

transmit}] violate-action {drop policed-dscp

 

transmit}]

 

Router(config)# no mls qos aggregate-policer

Deletes a named aggregate policer.

policer_name

 

 

 

1. The set-dscp-transmitand set-prec-transmitkeywords are only supported for IP traffic.
