Enabling Egress ACL Support for Remarked DSCP
To enable egress ACL support for remarked DSCP on an ingress interface, perform this task:
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
Step 1
Router(config)# interface {{vlan vlan_ID} |
{type
1
slot/port} | {port-channel number}}
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Selects the ingress interface to configure.
Step 2
Router(config-if)# platform ip features
sequential [access-group IP_acl_name_or_number]
Enables egress ACL support for remarked DSCP on the
ingress interface.
Router(config-if)# no platform ip features
sequential [access-group IP_acl_name_or_number]
Disables egress ACL support for remarked DSCP on the
ingress interface.
Step 3
Router(config-if)# end
Exits configuration mode.
Step 4
Router# show running-config interface
({type
1
slot/port} | {port-channel number}}
Verifies the configuration.
Command Purpose
Router(config)# mls qos aggregate-policer
policer_name bits_per_second normal_burst_bytes
[maximum_burst_bytes] [pir peak_rate_bps]
[[[conform-action {drop | set-dscp-transmit
1
dscp_value | set-prec-transmit
1
ip_precedence_value |
transmit}] exceed-action {drop | policed-dscp |
transmit}] violate-action {drop | policed-dscp |
transmit}]
1. The set-dscp-transmit and set-prec-transmit keywords are only supported for IP traffic.
Creates a named aggregate policer.
Router(config)# no mls qos aggregate-policer
policer_name
Deletes a named aggregate policer.
