Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.

Usage Guidelines

Before using the class command, you must use the policy-map global configuration command to identify the policy map and enter policy-map configuration mode. After specifying a policy map, you can configure a policy for new classes or modify a policy for any existing classes in that policy map. You attach the policy map to a port by using the service-policy interface configuration command.

After entering the class command, you enter the policy-map class configuration mode. These configuration commands are available:

admit—Admits a request for Call Admission Control (CAC)
bandwidth—Specifies the bandwidth allocated to the class.
exit—Exits the policy-map class configuration mode and returns to policy-map configuration mode.
no—Returns a command to its default setting.
police—Defines a policer or aggregate policer for the classified traffic. The policer specifies the bandwidth limitations and the action to take when the limits are exceeded. For more information about this command, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com.
priority—Assigns scheduling priority to a class of traffic belonging to a policy map.
queue-buffers—Configures the queue buffer for the class.
queue-limit—Specifies the maximum number of packets the queue can hold for a class policy configured in a policy map.
service-policy—Configures a QoS service policy.
set—Specifies a value to be assigned to the classified traffic. For more information, see set
shape—Specifies average or peak rate traffic shaping. For more information about this command, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com.

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

The class command performs the same function as the class-map global configuration command. Use the class command when a new classification, which is not shared with any other ports, is needed. Use the class-map command when the map is shared among many ports.

You can configure a default class by using the class class-default policy-map configuration command. Unclassified traffic (traffic that does not meet the match criteria specified in the traffic classes) is treated as default traffic.

You can verify your settings by entering the show policy-map privileged EXEC command.

Examples

This example shows how to create a policy map called policy1. When attached to the ingress direction, it matches all the incoming traffic defined in class1, sets the IP Differentiated Services Code Point (DSCP) to 10, and polices the traffic at an average rate of 1 Mb/s and bursts at 20 KB. Traffic exceeding the profile is marked down to a DSCP value gotten from the policed-DSCP map and then sent.

Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# police 1000000 20000 exceed-action policed-dscp-transmit
Switch(config-pmap-c)# exit

This example shows how to configure a default traffic class to a policy map. It also shows how the default traffic class is automatically placed at the end of policy-map pm3 even though class-default was configured first:

Switch# configure terminal 
Switch(config)# class-map cm-3
Switch(config-cmap)# match ip dscp 30
Switch(config-cmap)# exit

Switch(config)# class-map cm-4
Switch(config-cmap)# match ip dscp 40
Switch(config-cmap)# exit

Switch(config)# policy-map pm3
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# exit

Switch(config-pmap)# class cm-3
Switch(config-pmap-c)# set dscp 4
Switch(config-pmap-c)# exit

Switch(config-pmap)# class cm-4
Switch(config-pmap-c)# set precedence 5
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit

Command	Description
class-map	Creates a class map to be used for matching packets to the class whose name you specify and enters class-map configuration mode.
policy-map	Creates or modifies a policy map that can be attached to multiple physical ports or SVIs and enters policy-map configuration mode.
show policy-map	Displays QoS policy maps.
set	Classifies IP traffic by setting a DSCP or an IP-precedence value in the packet.

class-map

To create a class map to be used for matching packets to the class whose name you specify and to enter class-map configuration mode, use the class-map command in global configuration mode. Use the no form of this command to delete an existing class map and to return to global or policy map configuration mode.

class-map [ match-any | type ] class-map-name

no class-map [ match-any | type ] class-map-name

Syntax Description

match-any	(Optional) Perform a logical-OR of the matching statements under this class map. One or more criteria must be matched.
type	(Optional) Configures the CPL class map.
class-map-name	The class map name.

Command Default

No class maps are defined.

Command Modes

Global configuration

Policy map configuration

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.
Cisco IOS XE 3.3SE	The type keyword was added.

Usage Guidelines

Use this command to specify the name of the class for which you want to create or modify class-map match criteria and to enter class-map configuration mode.

The class-map command and its subcommands are used to define packet classification, marking, and aggregate policing as part of a globally named service policy applied on a per-port basis.

After you are in quality of service (QoS) class-map configuration mode, these configuration commands are available:

description—Describes the class map (up to 200 characters). The show class-map privileged EXEC command displays the description and the name of the class map.
exit—Exits from QoS class-map configuration mode.
match—Configures classification criteria.
no—Removes a match statement from a class map.

If you enter the match-any keyword, you can only use it to specify an extended named access control list (ACL) with the match access-group class-map configuration command.

To define packet classification on a physical-port basis, only one match command per class map is supported.

The ACL can have multiple access control entries (ACEs).

Examples

This example shows how to configure the class map called class1 with one match criterion, which is an access list called 103:

Switch(config)# access-list 103 permit ip any any dscp 10
Switch(config)# class-map class1
Switch(config-cmap)# match access-group 103
Switch(config-cmap)# exit

This example shows how to delete the class map class1:

Switch(config)# no class-map class1

You can verify your settings by entering the show class-map privileged EXEC command.

Syntax Description

access-group	Specifies an access group.
name acl-name	Specifies the name of an IP standard or extended access control list (ACL) or MAC ACL.
acl-index	Specifies the number of an IP standard or extended access control list (ACL) or MAC ACL. For an IP standard ACL, the ACL index range is 1 to 99 and 1300 to 1999. For an IP extended ACL, the ACL index range is 100 to 199 and 2000 to 2699.
class-map class-map-name	Uses a traffic class as a classification policy and specifies a traffic class name to use as the match criterion.
cos cos-value	Matches a packet on the basis of a Layer 2 class of service (CoS)/Inter-Switch Link (ISL) marking. The cos-value is from 0 to 7. You can specify up to four CoS values in one match cos statement, separated by a space.
dscp dscp-value	Specifies the parameters for each DSCP value. You can specify a value in the range 0 to 63 specifying the differentiated services code point value.
ip dscp dscp-list	Specifies a list of up to eight IP Differentiated Services Code Point (DSCP) values to match against incoming packets. Separate each value with a space. The range is 0 to 63. You also can enter a mnemonic name for a commonly used value.
ip precedence ip-precedence-list	Specifies a list of up to eight IP-precedence values to match against incoming packets. Separate each value with a space. The range is 0 to 7. You also can enter a mnemonic name for a commonly used value.
precedence precedence-value1...value4	Assigns an IP precedence value to the classified traffic. The range is 0 to 7. You also can enter a mnemonic name for a commonly used value.
qos-group qos-group-value	Identifies a specific QoS group value as a match criterion. The range is 0 to 31.
vlan vlan-id	Identifies a specific VLAN as a match criterion. The range is 1 to 4095.

Command Default

Command Modes

Class-map configuration

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.
Cisco IOS XE 3.3SE	The class-map class-map-name, cos cos-value, qos-group qos-group-value, and vlan vlan-id keywords were added.

Usage Guidelines

The match command is used to specify which fields in the incoming packets are examined to classify the packets. Only the IP access group or the MAC access group matching to the Ether Type/Len are supported.

If you enter the class-map match-anyclass-map-name global configuration command, you can enter the following match commands:

match access-group name acl-name

Note

The ACL must be an extended named ACL.
match ip dscp dscp-list
match ip precedence ip-precedence-list

The match access-group acl-index command is not supported.

To define packet classification on a physical-port basis, only one match command per class map is supported. In this situation, the match-any keyword is equivalent.

For the match ip dscp dscp-list or the match ip precedence ip-precedence-list command, you can enter a mnemonic name for a commonly used value. For example, you can enter the match ip dscp af11 command, which is the same as entering the match ip dscp 10 command. You can enter the match ip precedence critical command, which is the same as entering the match ip precedence 5 command. For a list of supported mnemonics, enter the match ip dscp ? or the match ip precedence ? command to see the command-line help strings.

Use the input-interface interface-id-list keyword when you are configuring an interface-level class map in a hierarchical policy map. For the interface-id-list, you can specify up to six entries.

Examples

This example shows how to create a class map called class2, which matches all the incoming traffic with DSCP values of 10, 11, and 12:

Switch(config)# class-map class2
Switch(config-cmap)# match ip dscp 10 11 12
Switch(config-cmap)# exit

This example shows how to create a class map called class3, which matches all the incoming traffic with IP-precedence values of 5, 6, and 7:

Switch(config)# class-map class3
Switch(config-cmap)# match ip precedence 5 6 7 
Switch(config-cmap)# exit

This example shows how to delete the IP-precedence match criteria and to classify traffic using acl1:

Switch(config)# class-map class2
Switch(config-cmap)# match ip precedence 5 6 7 
Switch(config-cmap)# no match ip precedence
Switch(config-cmap)# match access-group acl1
Switch(config-cmap)# exit

This example shows how to specify a list of physical ports to which an interface-level class map in a hierarchical policy map applies:

Switch(config)# class-map match-any class4
Switch(config-cmap)# match cos 4
Switch(config-cmap)# exit

This example shows how to specify a range of physical ports to which an interface-level class map in a hierarchical policy map applies:

Switch(config)# class-map match-any class4
Switch(config-cmap)# match cos 4
Switch(config-cmap)# exit

You can verify your settings by entering the show class-map privileged EXEC command.

policy-map

To create or modify a policy map that can be attached to multiple physical ports or switch virtual interfaces (SVIs) and to enter policy-map configuration mode, use the policy-map command in global configuration mode. Use the no form of this command to delete an existing policy map and to return to global configuration mode.

policy-map policy-map-name

no policy-map policy-map-name

Syntax Description

policy-map-name

Name of the policy map.

Command Default

No policy maps are defined.

Command Modes

Global configuration (config)

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.

Usage Guidelines

After entering the policy-map command, you enter policy-map configuration mode, and these configuration commands are available:

class—Defines the classification match criteria for the specified class map.
description—Describes the policy map (up to 200 characters).
exit—Exits policy-map configuration mode and returns you to global configuration mode.
no—Removes a previously defined policy map.
sequence-interval—Enables sequence number capability.

To return to global configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Before configuring policies for classes whose match criteria are defined in a class map, use the policy-map command to specify the name of the policy map to be created, added to, or modified. Entering the policy-map command also enables the policy-map configuration mode in which you can configure or modify the class policies for that policy map.

You can configure class policies in a policy map only if the classes have match criteria defined for them. To configure the match criteria for a class, use the class-map global configuration and match class-map configuration commands. You define packet classification on a physical-port basis.

Only one policy map per ingress port is supported. You can apply the same policy map to multiple physical ports.

You can apply a nonhierarchical policy maps to physical ports. A nonhierarchical policy map is the same as the port-based policy maps in the switch.

A hierarchical policy map has two levels in the format of a parent-child policy. The parent policy cannot be modified but the child policy (port-child policy) can be modified to suit the QoS configuration.

In VLAN-based QoS, a service policy is applied to an SVI interface. All physical interfaces belonging to a VLAN policy map then need to be configured to refer to the VLAN-based policy maps instead of the port-based policy map.

Note

Not all MQC QoS combinations are supported for wired and wireless ports. For information about these restrictions, see chapters "Restrictions for QoS on Wired Targets" and "Restrictions for QoS on Wireless Targets" in the QoS configuration guide.

Examples

This example shows how to create a policy map called policy1. When attached to the ingress port, it matches all the incoming traffic defined in class1, sets the IP DSCP to 10, and polices the traffic at an average rate of 1 Mb/s and bursts at 20 KB. Traffic less than the profile is sent.

Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# police 1000000 20000 conform-action transmit
Switch(config-pmap-c)# exit

This example show you how to configure hierarchical polices:

Switch# configure terminal
Switch(config)# class-map c1
Switch(config-cmap)# exit

Switch(config)# class-map c2
Switch(config-cmap)# exit

Switch(config)# policy-map child
Switch(config-pmap)# class c1
Switch(config-pmap-c)# priority level 1
Switch(config-pmap-c)# police rate percent 20 conform-action transmit exceed action drop
Switch(config-pmap-c-police)# exit
Switch(config-pmap-c)# exit

Switch(config-pmap)# class c2

Switch(config-pmap)# class class-default
Switch(config-pmap-c)# shape average 1000000
Switch(config-pmap-c)# service-policy child
Switchconfig-pmap-c)# end

This example shows how to delete a policy map:

Switch(config)# no policy-map policymap2

You can verify your settings by entering the show policy-map privileged EXEC command.

Related Commands

Command	Description
class	Defines a traffic classification match criteria for the specified class-map name.
class-map	Creates a class map to be used for matching packets to the class whose name you specify and enters class-map configuration mode.
service-policy (Wired)	Applies a policy map to a physical port or an SVI.
show policy-map	Displays QoS policy maps.

priority

To assign priority to a class of traffic belonging to a policy map, use the priority command in policy-map class configuration mode. To remove a previously specified priority for a class, use the no form of this command.

priority [ Kbps [ burst -in-bytes] | level level-value [ Kbps [ burst -in-bytes] ] | percent percentage [ Kb/s [ burst -in-bytes] ] ]

no priority [ Kb/s [ burst -in-bytes] | level level value [ Kb/s [ burst -in-bytes] ] | percent percentage [ Kb/s [ burst -in-bytes] ] ]

Syntax Description

Kb/s	(Optional) Guaranteed allowed bandwidth, in kilobits per second (kbps), for the priority traffic. The amount of guaranteed bandwidth varies according to the interface and platform in use. Beyond the guaranteed bandwidth, the priority traffic will be dropped in the event of congestion to ensure that the nonpriority traffic is not starved. The value must be between 1 and 2,000,000 kbps.
burst -in-bytes	(Optional) Burst size in bytes. The burst size configures the network to accommodate temporary bursts of traffic. The default burst value, which is computed as 200 milliseconds of traffic at the configured bandwidth rate, is used when the burst argument is not specified. The range of the burst is from 32 to 2000000 bytes.
level level-value	(Optional) Assigns priority level. Available values for level-value are 1 and 2. Level 1 is a higher priority than Level 2. Level 1 reserves bandwidth and goes first, so latency is very low. Reserve the bandwidth even if you do not use it. Both levels 1 and 2 can reserve bandwidth.
percent percentage	(Optional) Specifies the amount of guaranteed bandwidth to be specified by the percent of available bandwidth.

Command Default

No priority is set.

Command Modes

Policy-map class configuration (config-pmap-c)

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.
Cisco IOS XE 3.3SE	The Kbps, burst -in-bytes, and percent percentage keywords were added.

Usage Guidelines

This command configures low latency queuing (LLQ), providing strict priority queuing (PQ) for class-based weighted fair queuing (CBWFQ). Strict PQ allows delay-sensitive data such as voice to be dequeued and sent before packets in other queues are dequeued.

Note

You can configure a priority only with a level.

Only one strict priority or priority with levels is allowed in one policy-map. Multiple priorities with same priority levels without kbps/percent are allowed in a policy-map only if all of them are configured with police.

The priority command allows you to set up classes based on a variety of criteria (not just User Datagram Ports [UDP] ports) and assign priority to them, and is available for use on serial interfaces and ATM permanent virtual circuits (PVCs). A similar command, the ip rtp priority command, allows you to stipulate priority flows based only on UDP port numbers and is not available for ATM PVCs.

When the device is not congested, the priority class traffic is allowed to exceed its allocated bandwidth. When the device is congested, the priority class traffic above the allocated bandwidth is discarded.

The bandwidth and priority commands cannot be used in the same class, within the same policy map. However, these commands can be used together in the same policy map.

Within a policy map, you can give one or more classes priority status. When multiple classes within a single policy map are configured as priority classes, all traffic from these classes is queued to the same, single, priority queue.

When the policy map containing class policy configurations is attached to the interface to stipulate the service policy for that interface, available bandwidth is assessed. If a policy map cannot be attached to a particular interface because of insufficient interface bandwidth, the policy is removed from all interfaces to which it was successfully attached.

Examples

The following example shows how to configure the priority of the class in policy map policy1:

Switch(config)# class-map cm1
Switch(config-cmap)#match precedence 2
Switch(config-cmap)#exit

Switch(config)#class-map cm2
Switch(config-cmap)#match dscp 30
Switch(config-cmap)#exit

Switch(config)# policy-map policy1
Switch(config-pmap)# class cm1
Switch(config-pmap-c)# priority level 1
Switch(config-pmap-c)# police 1m
Switch(config-pmap-c-police)#exit
Switch(config-pmap-c)#exit
Switch(config-pmap)#exit

Switch(config)#policy-map policy1
Switch(config-pmap)#class cm2
Switch(config-pmap-c)#priority level 2
Switch(config-pmap-c)#police 1m

qos queue-softmax-multiplier

To increase the value of softmax buffer, use the qos queue-softmax-multiplier command in the global configuration mode.

qos queue-softmax-multiplier range-of-multiplier

no qos queue-softmax-multiplier range-of-multiplier

Syntax Description

range-of-multiplier

You can specify a value in the range of 100 to 1200. The default value is 100.

Command Default

None

Command Modes

Global configuration (config)

Command History

Release	Modification
Cisco IOS XE 3.6.3 and Cisco IOS XE 3.7.2	This command was introduced.

Usage Guidelines

Note

This command would take effect only on the ports where a policy-map is attached. If configured as 1200, the softmax for non-priority queues and non-primary priority queue (!=level 1) are multiplied by 12 with their default values. This command is not applicable for priority queue level 1.

queue-buffers ratio

To configure the queue buffer for the class, use the queue-buffers ratio command in policy-map class configuration mode. Use the no form of this command to remove the ratio limit.

queue-buffers ratio ratio limit

no queue-buffers ratio ratio limit

Syntax Description

ratio limit

(Optional) Configures the queue buffer for the class. Enter the queue buffers ratio limit (0-100).

Command Default

No queue buffer for the class is defined.

Command Modes

Policy-map class configuration (config-pmap-c)

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.

Usage Guidelines

Either the bandwidth, shape, or priority command must be used before using this command. For more information about these commands, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com

The switch allows you to allocate buffers to queues. If buffers are not allocated, then they are divided equally amongst all queues. You can use the queue-buffer ratio to divide it in a particular ratio. The buffers are soft buffers because Dynamic Threshold and Scaling (DTS) is active on all queues by default.

Note

The queue-buffer ratio is supported on both wired and wireless ports, but the queue-buffer ratio cannot be configured with a queue-limit.

Examples

The following example sets the queue buffers ratio to 10 percent:

Switch(config)# policy-map policy_queuebuf01
Switch(config-pmap)# class-map class_queuebuf01
Switch(config-cmap)# exit
Switch(config)# policy policy_queuebuf01
Switch(config-pmap)# class class_queuebuf01
Switch(config-pmap-c)# bandwidth percent 80
Switch(config-pmap-c)# queue-buffers ratio 10
Switch(config-pmap)# end

You can verify your settings by entering the show policy-map privileged EXEC command.

Command	Description
show policy-map	Displays QoS policy maps.

queue-limit

To specify or modify the maximum number of packets the queue can hold for a class policy configured in a policy map, use the queue-limit policy-map class configuration command. To remove the queue packet limit from a class, use the no form of this command.

queue-limit queue-limit-size [ packets ] { cos cos-value | dscp dscp-value } percent percentage-of-packets

no queue-limit queue-limit-size [ packets ] { cos cos-value | dscp dscp-value } percent percentage-of-packets

Syntax Description

queue-limit-size	The maximum size of the queue. The maximum varies according to the optional unit of measure keyword specified ( bytes, ms, us, or packets).
cos cos-value	Specifies parameters for each cos value. CoS values are from 0 to 7.
dscp dscp-value	Specifies parameters for each DSCP value. You can specify a value in the range 0 to 63 specifying the differentiated services code point value for the type of queue limit .
percent percentage-of-packets	A percentage in the range 1 to 100 specifying the maximum percentage of packets that the queue for this class can accumulate.

Command Default

None

Command Modes

Policy-map class configuration (policy-map-c)

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.

Usage Guidelines

Although visible in the command line help-strings, the packets unit of measure is not supported; use the percent unit of measure.

Note

This command is supported only on wired ports in the egress direction.

Weighted fair queuing (WFQ) creates a queue for every class for which a class map is defined. Packets satisfying the match criteria for a class accumulate in the queue reserved for the class until they are sent, which occurs when the queue is serviced by the fair queuing process. When the maximum packet threshold you defined for the class is reached, queuing of any further packets to the class queue causes tail drop.

You use queue limits to configure Weighted Tail Drop (WTD). WTD ensures the configuration of more than one threshold per queue. Each class of service is dropped at a different threshold value to provide for QoS differentiation.

You can configure the maximum queue thresholds for the different subclasses of traffic, that is, DSCP and CoS and configure the maximum queue thresholds for each subclass.

Examples

The following example configures a policy map called port-queue to contain policy for a class called dscp-1. The policy for this class is set so that the queue reserved for it has a maximum packet limit of 20 percent:

Switch(config)# policy-map policy11
Switch(config-pmap)# class dscp-1
Switch(config-pmap-c)# bandwidth percent 20
Switch(config-pmap-c)# queue-limit dscp 1 percent 20

Command History

Release	Modification
Cisco IOS XE 3.3SE	This command was introduced.

Usage Guidelines

A policy map is defined by the policy map command.

Only one policy map is supported per port, per direction. In other words, only one input policy and one output policy is allowed on any one port.

You can apply a policy map to incoming traffic on a physical port or on an SVI. QoS Configuration Guide (Catalyst 3650 Switches).

Note

Though visible in the command-line help strings, the history keyword is not supported, and you should ignore the statistics that it gathers.

Examples

This example shows how to apply plcmap1 to an physical ingress port:

Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# service-policy input plcmap1

This example shows how to remove plcmap2 from a physical port:

Switch(config)# interface gigabitethernet2/0/2
Switch(config-if)# no service-policy input plcmap2

The following example displays a VLAN policer configuration. At the end of this configuration, the VLAN policy map is applied to an interface for QoS:

Switch# configure terminal
Switch(config)# class-map vlan100
Switch(config-cmap)# match vlan 100
Switch(config-cmap)# exit
Switch(config)# policy-map vlan100
Switch(config-pmap)# policy-map class vlan100
Switch(config-pmap-c)# police 100000 bc conform-action transmit exceed-action drop
Switch(config-pmap-c-police)# end
Switch# configure terminal
Switch(config)# interface gigabitEthernet1/0/5
Switch(config-if)#  service-policy input vlan100

You can verify your settings by entering the show running-config privileged EXEC command.

set wlan user-priorityuser-priority-value | costable table-map-name | dscptable table-map-name | qos-grouptable table-map-name | wlantable table-map-name

Syntax Description

cos	Sets the Layer 2 class of service (CoS) value or user priority of an outgoing packet. You can specify these values: cos-value—CoS value from 0 to 7. You also can enter a mnemonic name for a commonly used value. Specify a packet-marking category to set the CoS value of the packet. If you also configure a table map for mapping and converting packet-marking values, this establishes the "map from" packet-marking category. Packet-marking category keywords: cos—Sets a value from the CoS value or user priority. dscp—Sets a value from packet differentiated services code point (DSCP). precedence—Sets a value from packet precedence. qos-group—Sets a value from the QoS group. wlan—Sets the WLAN user priority values. (Optional)table table-map-name—Indicates that the values set in a specified table map are used to set the CoS value. Enter the name of the table map used to specify the CoS value. The table map name can be a maximum of 64 alphanumeric characters. If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the CoS value. For example, if you enter the set cos precedence command, the precedence (packet-marking category) value is copied and used as the CoS value.
dscp	Sets the differentiated services code point (DSCP) value to mark IP(v4) and IPv6 packets. You can specify these values: cos-value—Number that sets the DSCP value. The range is from 0 to 63. You also can enter a mnemonic name for a commonly used value. Specify a packet-marking category to set the DSCP value of the packet. If you also configure a table map for mapping and converting packet-marking values, this establishes the "map from" packet-marking category. Packet-marking category keywords: cos—Sets a value from the CoS value or user priority. dscp—Sets a value from packet differentiated services code point (DSCP). precedence—Sets a value from packet precedence. qos-group—Sets a value from the QoS group. wlan—Sets a value from WLAN. (Optional)table table-map-name—Indicates that the values set in a specified table map will be used to set the DSCP value. Enter the name of the table map used to specify the DSCP value. The table map name can be a maximum of 64 alphanumeric characters. If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the DSCP value. For example, if you enter the set dscp cos command, the CoS value (packet-marking category) is copied and used as the DSCP value.
ip	Sets IP values to the classified traffic. You can specify these values: dscp—Specify an IP DSCP value from 0 to 63 or a packet marking category. precedence—Specify a precedence-bit value in the IP header; valid values are from 0 to 7 or specify a packet marking category.
precedence	Sets the precedence value in the packet header. You can specify these values: precedence-value— Sets the precedence bit in the packet header; valid values are from 0 to 7. You also can enter a mnemonic name for a commonly used value. Specify a packet marking category to set the precedence value of the packet. cos—Sets a value from the CoS or user priority. dscp—Sets a value from packet differentiated services code point (DSCP). precedence—Sets a value from packet precedence. qos-group—Sets a value from the QoS group. (Optional)table table-map-name—Indicates that the values set in a specified table map will be used to set the precedence value. Enter the name of the table map used to specify the precedence value. The table map name can be a maximum of 64 alphanumeric characters. If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the precedence value. For example, if you enter the set precedence cos command, the CoS value (packet-marking category) is copied and used as the precedence value.
qos-group	Assigns a QoS group identifier that can be used later to classify packets. qos-group-value—Sets a QoS value to the classified traffic. The range is 0 to 31. You also can enter a mnemonic name for a commonly used value. dscp—Sets the original DSCP field value of the packet as the QoS group value. precedence—Sets the original precedence field value of the packet as the QoS group value. (Optional)table table-map-name—Indicates that the values set in a specified table map will be used to set the DSCP or precedence value. Enter the name of the table map used to specify the value. The table map name can be a maximum of 64 alphanumeric characters. If you specify a packet-marking category (dscp or precedence) but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the QoS group value. For example, if you enter the set qos-group precedence command, the precedence value (packet-marking category) is copied and used as the QoS group value.
wlan user-priority wlan-user-priority	Assigns a WLAN user-priority to the classified traffic. You can specify these values: wlan-user-priority—Sets a WLAN user priority to the classified traffic. The range is 0 to 7. cos—Sets the Layer 2 CoS field value as the WLAN user priority. dscp—Sets the DSCP field value as the WLAN user priority. precedence—Sets the precedence field value as the WLAN user priority. wlan—Sets the WLAN user priority field value as the WLAN user priority. (Optional)table table-map-name—Indicates that the values set in a specified table map will be used to set the WLAN user priority value. Enter the name of the table map used to specify the value. The table map name can be a maximum of 64 alphanumeric characters. If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the WLAN user priority. For example, if you enter the set wlan user-priority cos command, the cos value (packet-marking category) is copied and used as the WLAN user priority.

Command Default

Command History

Release	Modification
Cisco IOS XE 3.3SECisco IOS XE 3.3SE	This command was introduced.
Cisco IOS XE 3.3SE	The cos, dscp, qos-group, wlantable table-map-name, keywords were added.

Usage Guidelines

For the set dscp dscp-value command, the set cos cos-value command, and the set ip precedence precedence-value command, you can enter a mnemonic name for a commonly used value. For example, you can enter the set dscp af11 command, which is the same as entering the set dscp 10 command. You can enter the set ip precedence critical command, which is the same as entering the set ip precedence 5 command. For a list of supported mnemonics, enter the set dscp ? or the set ip precedence ? command to see the command-line help strings.

When you configure the set dscp coscommand, note the following: The CoS value is a 3-bit field, and the DSCP value is a 6-bit field. Only the three bits of the CoS field are used.

When you configure the set dscp qos-group command, note the following:

The valid range for the DSCP value is a number from 0 to 63. The valid value range for the QoS group is a number from 0 to 99.
If a QoS group value falls within both value ranges (for example, 44), the packet-marking value is copied and the packets is marked.
If QoS group value exceeds the DSCP range (for example, 77), the packet-marking value is not be copied and the packet is not marked. No action is taken.

The set qos-group command cannot be applied until you create a service policy in policy-map configuration mode and then attach the service policy to an interface or ATM virtual circuit (VC).

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Examples

This example shows how to assign DSCP 10 to all FTP traffic without any policers:

Switch(config)# policy-map policy_ftp
Switch(config-pmap)# class-map ftp_class
Switch(config-cmap)# exit
Switch(config)# policy policy_ftp
Switch(config-pmap)# class ftp_class
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap)# exit

You can verify your settings by entering the show policy-map privileged EXEC command.

Usage Guidelines

Policy maps can include policers that specify the bandwidth limitations and the action to take if the limits are exceeded.

Note

Though visible in the command-line help string, the control-plane, session, and type keywords are not supported, and the statistics shown in the display should be ignored.

To display classification counters for ternary content addressable memory (TCAM) (marking or policing) based policies, enter the interface ID. Classification counters have the following restrictions:

Filter- based classification counters are not supported.
Classification counters are supported only on wired ports (in the ingress and egress directions).
Classification counters count packets instead of bytes.
Only QoS configurations with marking or policing trigger the classification counter.
As long as there is policing or marking action in the policy, the class-default will have classification counters.
Classification counters are not port based. The counters are shared across targets sharing the same policy map. This means that the classification counter aggregates all packets belonging to the same class of the same policy which attach to different interfaces.

Examples

This is an example of output from the show policy-map interface command, where classification counters are displayed:
