Chapter 40 Configuring Quality of Service
Configuring QoS
The following example shows how to enable marking action using table-map.
Switch(config)# table-map dscp2Cos
Switch(config-tablemap)# map from 8 to 1
Switch(config-tablemap)# exit
Switch(config)# policy-map p1
Switch(config-pmap)# class ipp5
Switch(config-pmap-c)# set cos dscp table dscp2Cos
Switch(config-pmap-c)# end
Switch# show policy-map p1
Policy Map p1
Class ipp5
set cos dscp table dscp2Qos
Switch# show table-map dscp2Cos
Table Map dscp2Cos
from 8 to 1

Configuring Policer Result-based Conditional Marking
To configure policer result-based conditional marking, setup a single rate or dual rate policer. Refer to
the “How to Implement Policing” section on page 40-17.
This example shows how to configure a two rate three-color policer with explicit actions for each policer
region:
Switch# configure terminal
Switch(config-pmap-c)# policer cir percent 20 pir percent 30
Switch(config-pmap-c-policer)# conform-action set-cos-transmit 3 set-dscp-transmit 10
Switch(config-pmap-c-policer)# exceed-action set-cos-transmit 4 set-dscp-transmit 20
Switch(config-pmap-c-policer)# violate action drop
Switch# show policy-map p1
Policy Map police
Class ipp5
police cir percent 20 pir percent 30
conform-action set-cos-transmit 3
conform-action set-dscp-transmit af11
exceed-action set-cos-transmit 4
exceed-action set-dscp-transmit af22
violate-action drop
Step 4
Switch(config-tablemap)# exit
Exits table-map configuration mode.
Step 5
Switch(config)# policy-map name
Enters policy-map configuration mode.
Step 6
Switch(config-p)# class name
Selects the class for QoS actions.
Step 7
Switch(config-p-c)# set cos | dscp |
prec cos | dscp | prec | qos-group
[table name]
Selects the marking action based on an implicit or explicit
table-map.
Step 8
Switch(config-p-c)# end
Exits configuration mode.
Step 9
Switch# show policy-map name
Verifies the configuration of the policy-map.
Step 10
Switch# show table-map name
Verifies the configuration of the table-map.
