Chapter 42 Configuring PFC QoS

Configuring PFC QoS

Note In the DSCP mutation map displays, the marked-down DSCP values are shown in the body of the matrix; the first digit of the original DSCP value is in the column labeled d1 and the second digit is in the top row. In the example shown, DSCP 30 maps to DSCP 08.

Attaching an Egress DSCP Mutation Map to an Interface

To attach an egress DSCP mutation map to an interface, perform this task:

 

Command

Purpose

Step 1

 

 

Router(config)# interface {{vlan vlan_ID}

Selects the interface to configure.

 

{type1 slot/port[.subinterface]}

 

 

{port-channelnumber[.subinterface]}}

 

Step 2

 

 

Router(config-if)#mls qos dscp-mutation

Attaches an egress DSCP mutation map to the interface.

 

mutation_map_name

 

 

Router(config-if)#no mls qos dscp-mutation

Removes the egress DSCP mutation map from the

 

mutation_map_name

interface.

Step 3

 

 

Router(config-if)# end

Exits configuration mode.

Step 4

 

 

Router# show running-config interface {{vlan

Verifies the configuration.

 

vlan_ID} {type1 slot/port} {port-channel

 

 

number}}

 

 

 

 

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

This example shows how to attach the egress DSCP mutation map named mutmap1 to 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)#mls qos dscp-mutation mutmap1

Router(config-if)# end

Configuring Ingress CoS Mutation on IEEE 802.1Q Tunnel Ports

Note The Supervisor Engine 2 does not support the switching modules that support ingress CoS mutation.

Release 12.2(17b)SXA and later releases support ingress CoS mutation on IEEE 802.1Q tunnel ports configured to trust received CoS (see the “Ingress CoS Mutation Configuration Guidelines and Restrictions” section on page 42-84for the list of supported modules).

When you configure ingress CoS mutation on an IEEE 802.1Q tunnel port that you have configured to trust received CoS, PFC QoS uses the mutated CoS value instead of the received CoS value in the ingress drop thresholds and for any trust CoS marking and policing.

These sections describe how to configure ingress CoS mutation:

•Ingress CoS Mutation Configuration Guidelines and Restrictions, page 42-84

•Configuring Ingress CoS Mutation Maps, page 42-85

•Applying Ingress CoS Mutation Maps to IEEE 802.1Q Tunnel Ports, page 42-85
