VMI QoS

The VMI QoS feature supports full modular quality of service (QoS) CLI (MQC) configurations on virtual multipoint interfaces. QoS configurations include remarking, shaping, and policing.

The VMI provides services that map outgoing packets to the appropriate PPP over Ethernet (PPPoE) sessions based on the next-hop forwarding address for that packet.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table.

Restrictions for VMI QoS

You can apply the quality of service (QoS) policy to only one outgoing interface that the PPP over Ethernet (PPPoE) session is traversing.

Information About VMI QoS

VMI QoS

Virtual multipoint interfaces (VMIs) support full modular quality of service (QoS) CLI (MQC) configurations, which includes remarking, shaping, and policing. For details, see the QoS Modular QoS Command-Line Interface Configuration Guide publication that is part of the Quality of Service Solutions Configuration Guide Library.


Note

Quality of service (QoS) is not supported on Virtual multipoint interfaces (VMIs).

Configuration Examples for VMI QoS

Examples: QoS Configuration for VMI

The following example shows a configuration for quality of service (QoS) features: 


class-map match-any chat            
 match dscp af11            
class-map match-any voice            
 match dscp ef            
class-map match-any af23            
 match dscp af23            
class-map match-any af31            
 match dscp af31            
class-map match-any af33            
 match dscp af33            
class-map match-any af42            
 match dscp af42             
policy-map multiple_sessions            
 class chat            
 bandwidth 50            
 class voice            
 bandwidth 100            
 class af23            
 bandwidth 150            
 class af31            
 bandwidth 200            
 class af33            
 bandwidth 250            
 class af42            
 bandwidth 300             
 interface virtual-template 1            
service-policy output multiple_sessions

The following example shows a configuration for shaping: 


class-map match-any chat
match dscp af11
class-map match-any voice
match dscp ef
policy-map shape_child
class chat
bandwidth 200
class voice
priority 100
policy-map shape_parent
class class-default
shape average 400000
service-policy shape_child

The following example shows a configuration for assigning a policy to a virtual multipoint interface (VMI): 


interface vmi1
service-policy output shape_parent

The following example shows a configuration for policing actions: 


class-map match-any af12
match dscp af12
class-map match-any af41
match dscp af41
policy-map police
class af12
police 1000000 conform-action set-dscp-transmit af31 exceed-action set-dscp-transmit af23 violate-action set-dscp-transmit af23
class af41
police 1000000 conform-action transmit exceed-action drop violate-action drop

The following example shows a configuration for assigning a policy to a virtual template interface: 


interface virtual-template 1
service-policy output police
