Chapter 42 Configuring PFC QoS

Configuring PFC QoS

Router(config)# interface gigabitethernet 6/1

Router(config-if)# mls qos trust dscp

Router(config-if)# end

Router#

This example shows how to verify the configuration:

Router# show queueing interface gigabitethernet 6/1 include Trust state

Trust state: trust DSCP

Mapping DSCP Values to Standard Receive-Queue Thresholds

To map DSCP values to the standard receive-queue thresholds, perform this task:

 

Command

Purpose

Step 1

 

 

Router(config)# interface tengigabitethernet

Selects the interface to configure.

 

slot/port

 

Step 2

 

 

Router(config-if)# rcv-queuedscp-mapqueue_#

Maps DSCP values to the standard receive queue

 

threshold_# dscp1 [dscp2 [dscp3 [dscp4 [dscp5

thresholds.

 

[dscp6 [dscp7 [dscp8]]]]]]]

 

 

Router(config-if)#no rcv-queue dscp-map

Reverts to the default mapping.

Step 3

 

 

Router(config-if)# end

Exits configuration mode.

Step 4

 

 

Router# show queueing interface

Verifies the configuration.

 

tengigabitethernet slot/port

 

 

 

 

When mapping DSCP values, note the following information:

•You can enter up to 8 DSCP values that map to a queue and threshold.

•You can enter multiple commands to map additional DSCP values to the queue and threshold.

•You must enter a separate command for each queue and threshold.

This example shows how to map the DSCP values 0 and 1 to threshold 1 in the standard receive queue for 10-Gigabit Ethernet port 6/1 port 6/1:

Router# configure terminal

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

Router(config)# interface tengigabitethernet 6/1

Router(config-if)#rcv-queue dscp-map 1 1 0 1

Router(config-if)# end

Router#
