Network QoS Policies

This chapter provides information to configure network QoS policies using the command line interface (CLI).

Topics in this chapter include:

Overview

The network QoS policy consists of an ingress and egress component for interfaces in the IP domain, and a ring component for interfaces in the bridging domain.

The ingress component of the QoS policy defines how DSCP bits (for GRE and IP) and multiprotocol label switching (MPLS) Experimental (EXP) bits are mapped to internal forwarding class and profile state. The forwarding class and profile state define the per-hop behavior (PHB) or the QoS treatment through the 7705 SAR.

The egress component of the QoS policy defines the DSCP bit, MPLS EXP bit, and the dot1p marking based on the forwarding class and the profile state.

The ring component of the QoS policy defines how dot1p bits are mapped to network queue and profile state.

The mapping on each network interface defaults to the mappings defined in the default network QoS policy until an explicit policy is defined for the network interface. Network policy-id 1 exists as the default policy that is applied to all network interfaces by default. The network policy-id 1 cannot be modified or deleted. For the ingress, it defines the default DSCP-to-FC and profile state, and MPLS EXP-to-FC and profile state mappings. For the egress, it defines eight forwarding classes and profile states that represent the packet marking criteria. For the ring, it defines eight dot1p-to-queue and profile state mappings.

New (non-default) network policy parameters can be modified. The no form of the command reverts to the default values.

Changes made to a policy are applied immediately to all network interfaces where the policy is applied. For this reason, when a policy requires several changes, it is recommended that you copy the policy to a work area policy-id. The work-in-progress copy can be modified until all the changes are made, and then the original policy-id can be overwritten with the config qos copy command.

For information about the tasks and commands necessary to access the command line interface and to configure and maintain your 7705 SAR devices, refer to the 7705 SAR Basic System Configuration Guide, ‟CLI Usage”.

Basic Configuration

This section contains the following topics related to creating and applying network QoS policies for the IP domain and the bridging domain:

A basic network QoS policy must conform to the following rule:

  • Each network QoS policy must have a unique policy ID.

Configuring a Network QoS Policy

Configuring and applying QoS policies other than the default policy is optional.

Define the following parameters to configure a network QoS policy (see Default Network QoS Policy Values for default values):

  • a network policy ID value — the system does not dynamically assign a value

  • a network policy type — the type of network policy can be ip-interface for IP domain policies (to configure ingress and egress criteria), or ring for bridging domain policies (to configure ring criteria), or default (to set any network policy to its default values)

  • a description — a text string description of policy features

  • scope — the policy scope as exclusive or template

  • egress criteria — you can modify egress criteria to customize the forwarding class to be instantiated. Otherwise, the default values are applied.

    • dot1p — the dot1p-in-profile and dot1p-out-profile mapping for the forwarding class

    • DSCP — the DSCP value is used for all GRE and IP packets (in or out of profile) requiring marking that egress on this forwarding class

    • LSP EXP — the EXP value is used for all MPLS labeled packets (in or out of profile) requiring marking that egress on this forwarding class

  • ingress criteria — the DSCP to forwarding class mapping for all GRE and IP packets and the MPLS EXP bits to forwarding class mapping for all labeled packets

    • default-action — the default action to be taken for packets that have undefined DSCP or MPLS EXP bits set. The default-action specifies the forwarding class to which such packets are assigned. The default-action is automatically created when the policy is created.

    • DSCP —  a mapping between the DSCP bits of the network ingress traffic and the forwarding class. Ingress traffic that matches the specified DSCP bits will be assigned to the corresponding forwarding class.

    • LSP EXP — a mapping between the LSP EXP bits of the network ingress traffic and the forwarding class. Ingress traffic that matches the specified LSP EXP bits will be assigned to the corresponding forwarding class.

  • ring criteria — the dot1p-to-queue mapping for all packets arriving on a bridging domain port (that is, a ring port or the add/drop port)

    • default-action — the default action to be taken for packets that have undefined dot1p bits set. The default-action specifies the queue to which such packets are assigned and the profile state of the packets. The default-action is automatically created when the policy is created.

    • dot1p — a mapping of the dot1p bits of the ingress traffic to the queue and the profile state

Creating a Network QoS Policy

Configuring and applying network QoS policies other than the default policy is optional.

Use the following CLI syntax to create a network QoS policy for router interfaces (ip-interface type) and ring port (ring type).

The ip-interface keyword is optional for router interface network policies.

Use the ring keyword to create a network QoS policy that can be applied to a bridging domain port (that is, a ring port or the add/drop port). Up to eight dot1p-to-queue and profile mappings can be defined under the ring command.

CLI Syntax:
config>qos# 
    network network-policy-id [create] [network-policy-type {ip-interface | ring | default}] 
        description description-string 
        scope {exclusive|template}
        egress
            fc {be|l2|af|l1|h2|ef|h1|nc}
                dot1p dot1p-priority
                dot1p-in-profile dot1p-priority
                dot1p-out-profile dot1p-priority
                dscp-in-profile dscp-name
                dscp-out-profile dscp-name
                lsp-exp-in-profile lsp-exp-value
                lsp-exp-out-profile lsp-exp-value
        ingress
            default-action fc {be|l2|af|l1|h2|ef|h1|nc} profile {in|out}
            dscp dscp-name fc {be|l2|af|l1|h2|ef|h1|nc} profile {in|out}
            ler-use-dscp
            lsp-exp lsp-exp-value fc fc-name profile {in|out}
        ring
            default-action queue queue-id profile {in | out}
            dot1p dot1p-priority queue queue-id profile {in|out}
        exit
Example:
configure qos network 700 create network-policy-type ip-interface
config>qos>network$ description "Net Policy"
config>qos>network$ scope template
config>qos>network$ egress fc be
config>qos>network>egress>fc$ dot1p 1
config>qos>network>egress>fc$ lsp-exp-in-profile 2
config>qos>network>egress>fc$ lsp-exp-out-profile 3
config>qos>network>egress>fc$ exit
config>qos>network$ ingress
config>qos>network>ingress$ default-action fc be profile in
config>qos>network>ingress$ exit
config>qos>network$ exit

The following output displays the configuration for an ip-interface type network policy 700:

*A:ALU-1>config>qos# info
---------------------------------------------------
echo "QoS Policy Configuration"
#--------------------------------------------------
network 700 network-policy-type ip-interface create

                    dot1p-in-profile 1
                    dot1p-out-profile 1
                exit
            exit
        exit
---------------------------------------------------

The following example creates a ring type network QoS policy on the 2-port 10GigE (Ethernet) Adapter card or 2-port 10GigE (Ethernet) module.

Example:
config>qos>network 5 network-policy-type ring create 
config>qos>network>ring# default-action queue 1 profile out
config>qos>network>ring# dot1p 1 queue 4 profile in
config>qos>network>ring# dot1p 5 queue 6 profile out
config>qos>network>ring# exit
config>qos>network# scope template
config>qos>network# exit

The following output displays the configuration for ring network policy 5:

Applying Network QoS Policies

You can apply network QoS policies to router interfaces and a ring adapter card.

Use the following CLI syntax to apply network policies to router interfaces:

CLI Syntax:
config>router
    interface interface-name
        qos network-policy-id
Example:
config>router# interface ALU-1
config>router>if$ qos 700
config>router>if$ exit

The following output displays the configuration for router interface ALU-1 with network policy 700 applied to the interface.

A:ALU-1>config>router# info
#--------------------------------------------------
echo "IP Configuration"
#--------------------------------------------------
        interface "ALU-1"
            qos 700
        exit
        interface "ip-10.0.0.2"
            address 10.10.0.2/16
        exit
---------------------------------------------------

Use the following CLI syntax to apply a ring type network policy to a ring adapter card. Applying the policy to the card means that the policy is applied to ingress traffic of the ring ports and the add/drop port:

CLI Syntax:
config>card>mda>network
    ring
        qos-policy network-policy-id
Example:
config# card 1
config>card# mda 8
config>card>mda# network ring 
config>card>mda>network>ring# qos-policy 5

The following output displays the configuration for ring type network policy 5 applied to a ring adapter card.

*A:7705custDoc:Sar18>config>card>mda>network# info detail
----------------------------------------------
                ingress
                    fabric-policy 1
                    queue-policy "default"
                exit
                ring
                    qos-policy 5
                    add-drop-port-queue-policy "default"
                exit
----------------------------------------------
*A:7705custDoc:Sar18>config>card>mda>network#

Default Network QoS Policy Values

The default network policy is identified as policy-id 1. Default policies cannot be modified or deleted. Default Network QoS Policy DSCP-to-Forwarding Class Mappings, Default Network QoS Policy LSP EXP-to-Forwarding Class Mappings , and Default Network QoS Policy Dot1p-to-Queue Class Mappings (found in the section on Network and Network Queue QoS Policies) list the default network QoS policy parameters for ingress, egress, and ring policies.

The following output displays the default network policy configuration:

Service Management Tasks

This section describes the following service management tasks:

Deleting QoS Policies

A network policy is associated by default with router interfaces. You can replace the default policy with a non-default policy, but you cannot entirely remove the policy from the configuration. When you remove a non-default policy, the policy association reverts to the default network policy-id 1.

Use the following syntax to delete a network policy.

CLI Syntax:
config>qos# no network network-policy-id
Example:
config>qos# no network700

Copying and Overwriting Network Policies

You can copy an existing network policy to a new policy ID value or overwrite an existing policy ID. The overwrite option must be specified or an error occurs if the destination policy ID exists.

Use the following syntax to overwrite an existing policy ID.

CLI Syntax:
config>qos# copy network source-policy-id dest-policy-id [overwrite]
Example:
config>qos# copy network 1 600
  config>qos# copy slope-policy 600 700 
  MINOR: CLI Destination "700" exists use {overwrite}.
  config>qos# copy slope-policy 600 700 overwrite
  config>qos# 

The following output displays copied policies:

ALU-12>config>qos# info detail

                default-action fc be profile out
...
---------------------------------------------
ALU-12>config>qos# 

Editing QoS Policies

You can change existing policies, except the default policies, and entries in the CLI. The changes are applied immediately to all interfaces where the policy is applied. To prevent configuration errors, use the copy command to make a duplicate of the original policy in a work area, make the edits, and then overwrite the original policy.

Description

This command associates a text string with a configuration context to help identify the context in the configuration file.

The no form of this command removes any description string from the context.

Default

n/a

Parameters
description-string

a text string describing the entity. Allowed values are any string up to 80 characters long composed of printable, 7-bit ASCII characters. If the string contains special characters (such as #, $, or spaces), the entire string must be enclosed within double quotes.

Network QoS Policy Commands
network
Syntax

[no] network network-policy-id [create] [network-policy-type {ip-interface | ring | default}]

Context

config>qos

Description

This command creates or edits a QoS network policy. The network policy defines the treatment that GRE, IP, or MPLS packets receive as they ingress and egress the network port.

The network-policy-type keyword defines the type of network policy that will be created. The ip-interface type network policy is assigned to router interfaces. The ring type network policy is assigned to bridging domain ports on a ring adapter card.

Using the network-policy-type keyword is optional. If network-policy-type is not used, a default ip-interface policy is created.

Note: With the addition of ring ports on the 2-port 10GigE (Ethernet) Adapter card, the network-policy-type keyword allows the creation of network QoS policies for IP interfaces in the IP domain (that is, ingress and egress network ports) and for ring policies in the bridging domain.

Network policy-id 1 exists as the default policy that is applied to all network interfaces by default. Network policy-id 1 cannot be modified or deleted, and is reapplied when the network-policy-type default keyword is used.

If a new network policy is created for the IP domain (for instance, policy-id 2), only the default action and egress forwarding class parameters are identical to the default policy-id 1. A new network policy does not contain the default DSCP-to-FC or MPLS EXP-to-FC mapping. To create a new network policy that includes the default ingress DSCP-to-FC or MPLS EXP-to-FC mapping, the default network policy-id 1 can be copied (using the copy command). You can modify parameters or use the no modifier to remove an object from the configuration. Similarly, the copy and modify process is used to create a new ring type network policy, where the dot1p-to-queue and profile state mapping are available for use in the new policy.

Any changes made to an existing policy, using any of the sub-commands, will be applied immediately to all network interfaces where this policy is applied. For this reason, when many changes are required on a policy, it is highly recommended that the policy be copied to a work area policy-id. That work-in-progress policy can be modified until complete and then written over the original policy-id. Use the config qos copy command to maintain policies in this manner.

The no form of this command deletes the network policy. A policy cannot be deleted until it is removed from all services where it is applied. The default network policy policy-id 1 cannot be deleted.

Default

System Default Network Policy 1 defined

Parameters
network-policy-id

uniquely identifies the policy on the 7705 SAR

Values

1 to 65535

Default

1

create

keyword used to create a network QoS policy

network-policy-type {ip-interface | ring | default}

keyword used to define the type of network policy

Values

ip-interface: creates a network QoS policy for the IP domain by providing access to the egress and ingress commands

ring: creates a ring network QoS policy for the bridging domain by providing access to the ring command

default: sets the network policy type to policy ID 1

scope
Syntax

scope {exclusive | template}

no scope

Context

config>qos>network

Description

This command configures the network policy scope as exclusive or template. The policy’s scope cannot be changed if the policy is applied to an interface.

The no form of this command sets the scope of the policy to the default of template.

Default

template

Parameters
exclusive

when the scope of a policy is defined as exclusive, the policy can only be applied to one network. If a policy with an exclusive scope is assigned to a second network, an error message is generated. If the policy is removed from the exclusive network, it will become available for assignment to another exclusive network.

The system default policies cannot be defined as exclusive scope. An error will be generated if scope exclusive is executed in any policies with a policy-id equal to 1.

template

when the scope of a policy is defined as template, the policy can be applied to multiple networks on the router.

Default QoS policies are configured with template scopes. An error is generated if you try to modify the template scope parameter to exclusive scope on default policies.

Network Egress QoS Policy Commands
egress
Syntax

egress

Context

config>qos>network

Description

This command is used to enter the CLI mode that creates or edits egress policy entries that specify the forwarding class to be instantiated when this policy is applied to the network port.

The forwarding class and profile state mapping to in-profile and out-of-profile DSCP and MPLS EXP bits mapping for all labeled packets are also defined under this node.

For MPLS tunnels, if network egress Ethernet ports are used, dot1p bit marking can be enabled in conjunction with EXP bit marking. In this case, the tunnel and pseudowire EXP bits do not have to be the same as the dot1p bits.

For GRE and IP tunnels, dot1p marking and pseudowire EXP marking can be enabled, and DSCP marking can also be enabled.

The service packets are transported over an MPLS LSP, GRE tunnel, or IP tunnel.

All out-of-profile service packets are marked with the corresponding DSCP (for GRE or IP packets) or EXP (for MPLS packets) bit value at network egress. All in-profile service packets are marked with the corresponding in-profile DSCP or EXP bit value based on the forwarding class they belong to.

fc
Syntax

[no] fc fc-name

Context

config>qos>network>egress

Description

This command specifies the forwarding class name. The fc fc-name represents a CLI parent node that contains sub-commands or parameters describing the marking criteria for that forwarding class. The fc command overrides the default parameters for that forwarding class defined in the network default policy-id 1.

The no form of this command reverts to the defined parameters in the default network policy policy-id 1. If the fc-name is removed from the default network policy policy-id 1, that forwarding class reverts to the factory defaults.

Default

Undefined forwarding classes default to the configured parameters in the default network policy policy-id 1.

Parameters
fc-name

the case-sensitive, system-defined forwarding class name for which policy entries will be created

Values

be, l2, af, l1, h2, ef, h1, nc

Default

Network Ingress QoS Policy Commands
ingress
Syntax

ingress

Context

config>qos>network

Description

This command is used to enter the CLI mode that creates or edits policy entries that specify the DSCP to forwarding class mapping for all GRE or IP packets and define the MPLS EXP bits to forwarding class mapping for all labeled packets.

When pre-marked GRE, IP, or MPLS packets ingress on a network port, they get a per-hop behavior (that is, the QoS treatment through the 7705 SAR based on the mapping defined under the current node).

default-action
Syntax

default-action fc fc-name profile {in | out}

Context

config>qos>network>ingress

Description

This command defines or edits the default action to be taken for packets that have  undefined DSCP or MPLS EXP bits set. The default-action command specifies the forwarding class to which such packets are assigned.

Multiple default-action commands will overwrite each previous default-action command.

Default

n/a

Parameters
fc-name

specifies the forwarding class name. All packets with DSCP or MPLS EXP bits not defined will be placed in this forwarding class.

Values

be, l2, af, l1, h2, ef, h1, nc

Default

be

profile {in | out}

all packets that are assigned to this forwarding class will be considered in or out of profile based on this command. In case of congestion, the in-profile packets are preferentially queued over the out-of-profile packets.

Values

in, out

Default

out

dscp
Syntax

dscp dscp-name fc fc-name profile {in | out}

no dscp

Context

config>qos>network>ingress

Description

This command creates a mapping between the DSCP of the network ingress traffic and the forwarding class for GRE or IP packets.

Ingress traffic that matches the specified DSCP is assigned to the corresponding forwarding class. Multiple commands can be entered to define the association of some or all 64 DSCP values with the forwarding class. For undefined code points, packets are assigned to the forwarding class specified under the default-action command.

The no form of this command removes the DSCP-to-FC association. The default-action then applies to that code point value.

Default

n/a

Parameters
dscp-name

specifies the DSCP to be associated with the forwarding class. The DSCP value is derived from the most significant six bits in the IP header ToS byte field (DSCP bits). The six DSCP bits define 64 DSCP values used to map packets to per-hop QoS behavior.

A maximum of 64 DSCP rules are allowed on a single policy. The specified name must exist as a dscp-name. Valid DSCP Names lists all the valid DSCP names.

Values

in, out

Default

out

ler-use-dscp
Syntax

[no] ler-use-dscp

Context

config>qos>network>ingress

Description

This command is used to override tunnel QoS mapping on all ingress network IP interfaces that the network-policy-id is associated with. The command may be defined at any time after the network QoS policy has been created.

For IP traffic riding over MPLS or GRE tunnels that will be routed to the base router, a VRPN interface, or an IES interface at the tunnel termination point (the eLER), this command makes it possible for the 7705 SAR to ignore the EXP/DSCP bits in the tunnel header when the packets arrive at the eLER. This is useful when the mapping for the tunnel QoS marking does not completely reflect the required QoS handling for the IP routed packet. When the command is enabled on an ingress network IP interface, the IP interface will ignore the tunnel’s QoS mapping and will derive the internal forwarding class and associated profile state based on the DSCP values of the IP header ToS field. This command applies only on the eLER where the tunnel or service is terminated and the next header in the packet is IP.

The default state is to not enforce customer DSCP at the tunnel-termination point, IP-routed QoS override within the network QoS policy.

The no form of the command removes use of customer DSCP at tunnel-termination, IP-routed QoS override from the network QoS policy and all ingress network IP interfaces associated with the policy.

Default

no ler-use-dscp

lsp-exp
Syntax

lsp-exp lsp-exp-value fc fc-name profile {in | out}

no lsp-exp lsp-exp-value

Context

config>qos>network>ingress

Description

This command creates a mapping between the LSP EXP bits of the network ingress traffic and the forwarding class.

Ingress traffic that matches the specified LSP EXP bits will be assigned to the corresponding forwarding class. Multiple commands can be entered to define the association of some or all of the eight LSP EXP bit values with the forwarding class. For undefined values, packets are assigned to the forwarding class specified under the default-action command.

The no form of this command removes the association of the LSP EXP bit value with the forwarding class. The default-action then applies to that LSP EXP bit pattern.

Default

n/a

Self-generated Traffic Commands
sgt-qos
Syntax

sgt-qos

Context

config>router

Description

This command enables the context to configure DSCP or dot1p re-marking for self-generated traffic (SGT).

application
Syntax

application dscp-app-name dscp {none | dscp-value | dscp-name} [fc-queue fc-name profile {in | out}]

application dot1p-app-name dot1p {none | dot 1p-priority} [fc-queue fc-name profile {in | out}]

no application {dscp-app-name | dot1p-app-name}

Context

config>router>sgt-qos

Description

This set of commands configures DSCP marking for self-generated IP traffic or dot1p marking for self-generated non-IP traffic (specifically, IS-IS and ARP traffic).

When an IP or Layer 3 application is configured using the dscp-app-name parameter, the specified DSCP name or DSCP value is used for all packets generated by this application within the router instance in which it is configured. The value set in this command sets the DSCP value in the egress IP header. The egress QoS policy will not overwrite this value.

When a Layer 2 application is configured using the dot1p-app-name parameter, the specified dot1p priority value is used for all packets generated by this application within the router instance in which it is configured.

Only one name or value can be configured per application. If multiple entries are configured, a subsequent entry overrides the previously configured entry.

The fc-queue option redirects SGT applications to egress data queues rather than the default control queue by assigning them to a forwarding class. If this option is configured, the profile state must be set. All packets that are assigned to this forwarding class will be considered in-profile or out-of-profile based on the configuration. In case of congestion, the in-profile packets are preferentially queued over the out-of-profile packets.

If the fc-queue option is used with the dscp-app-name application, any configuration done using the sgt-qos>dscp command is ignored for packets generated by this application, as illustrated in the following examples:

sgt-qos>application telnet dscp cp1

sgt-qos>dscp cp1 fc af

sgt-qos>application ftp dscp cp1 fc-queue be profile out

sgt-qos>dscp cp1 fc af

In the first example, all packets generated by the Telnet application use DSCP CP1 and map to FC AF as configured in the dscp command. The dot1p bits of the outgoing packets are marked from the value that FC AF points to in the egress QoS policy.

In the second example, all packets generated by the FTP application use DSCP CP1 and map to FC BE as dictated by the fc-queue redirection. The dot1p bits of the outgoing packets are marked from the value that FC BE points to in the egress QoS policy. Because redirection is configured, the mapping configured with the dscp command is ignored.

Note: The above behavior applies to all SGT IP applications with the exception of VRRP, where the dot1p value is always set to 7, regardless of the value in the FC egress QoS policy.

If the fc-queue option is used with the dot1p-app-name application, the dot1p bits of the outgoing packets are marked with the value set with the dot1p-priority parameter, regardless of the value in the FC egress queue policy.

The no form of this command resets the DSCP or dot1p value for the application to its default value and resets the application to use the egress control queue.

Default

n/a

Parameters
dscp-app-name

the DSCP application name

Values

bgp, cflowd, dhcp, dns, ftp, icmp, igmp, ldp, mcfw, mld, ndis, ntp, ospf, pim, ptp, radius, rip, rsvp, snmp, snmp-notification, ssh, syslog, tacplus, telnet, tftp, traceroute, vrrp

Note:

  • PTP in the context of SGT QoS is defined as Precision Timing Protocol and is an application in the 7705 SAR. The PTP application name is also used in areas such as event-control and logging. Precision Timing Protocol is defined in IEEE 1588-2008.

  • PTP in the context of IP filters is defined as Performance Transparency Protocol. IP protocols can be used as IP filter match criteria; the match is made on the 8-bit protocol field in the IP header.

dscp-value

the value that maps to the DSCP name (the value none specifies that the default DSCP value for the application be used; see Applications and Support for Configurable DSCP or dot1p Markings)

Values

none | 0 to 63

dscp-name

the DSCP to be associated with the forwarding class. Valid DSCP Names lists the valid DSCP names.

dot1p-app-name

the dot1p application name

Values

arp, isis

dot1p-priority

the dot1p priority (the value none specifies that the default dot1p value for the application be used; see Applications and Support for Configurable DSCP or dot1p Markings)

Values

none | 0 to 7

fc-name

the forwarding class assigned to SGT applications redirected to data queues

Values

be, l2, af, l1, h2, ef, h1, nc

profile {in | out}

the profile state of packets assigned to the specified forwarding class; this parameter must be specified when the fc-queue parameter is configured

dscp
Syntax

dscp dscp-name fc fc-name

no dscp dscp-name

Context

config>router>sgt-qos

Description

This command creates a mapping between the DSCP of the self-generated traffic and the forwarding class. The forwarding class dot1p network QoS policy mapping is used to mark the dot1p bits of the Layer 3 or IP application. For example, configuring the dscp-name parameter as be and the fc-name parameter as l1 results in marking the dot1p bits of the outgoing Ethernet frame, which is transporting self-generated IP traffic with DSCP bits set to BE, to the value that FC L1 points to in the network QoS policy (as configured in the config>qos>network>egress>fc context).

Note: The dot1p class of service may not apply to all IP traffic and is dependent on the egress port encapsulation type.

Based on this configured FC, the network QoS policy for the egress forwarding complex sets the IEEE 802.1 dot1p bits.

Multiple commands can be entered to associate some or all of the 64 DSCP values with the forwarding class. For undefined code points, packets are assigned to the default forwarding class for the DSCP value. This value can be seen in the show>router>sgt-qos>dscp-map output under the Default FC Value column.

The no form of the command resets the DSCP value to its default forwarding class.

Note: If the fc-queue option is configured in the sgt-qos>application dscp-app-name command, the mapping created with this command is ignored for packets generated by the applications that are configured with the option.

The following table lists the default FC value for each DSCP value.
