Configuration Examples for VLAN Tag-Based QoS

Configuring a VLAN Tag-Based QoS Policy: Example

The following configuration example shows how to configure a VLAN tag-based QoS policy using the
PRE3 hierarchical queuing framework. In the example, the policy map named service1 defines QoS
services for two VLAN traffic classes: vlans_5_to_10 and vlans_11_to_14. The child-policy1 defines
QoS services for voice, video, data, and default traffic, and is applied to both of the VLAN classes in
service1.

policy-map service1

Configuring a VLAN Tag-Based QoS Policy: Invalid Configuration Example

The following configuration example shows an invalid configuration in which the subinterface-shaper
policy is attached to the Gigabit Ethernet subinterface 1/1/1.5 and the vlangroup-shapers policy is
attached to the main interface, Gigabit Ethernet interface 1/1/1. In this example, the traffic classes
defined in the subinterface-shaper policy match the VLAN-group classes in the vlangroup-shapers
policy. As a result, this configuration is invalid because the router does not support the attachment of a
QoS policy on a subinterface that matches any of the VLAN-group traffic classes in a policy attached to
the main interface.
