Chapter 21 VLAN Tag-Based Quality of Service
Configuration Examples for VLAN Tag-Based QoS
Example
The following example configuration shows how to attach a VLAN tag-based policy named policy1 to
the Gigabit Ethernet main interface 1/0/0 for outbound traffic.
Router(config)# class-map match-any vlan-customer1
Router(config-cmap)# match vlan 10 -20
Router(config-cmap)# class-map child
Router(config-cmap)# match prec 1
Router(config-cmap)# exit
Router(config)# policy-map child-cust1
Router(config-pmap)# class child
Router(config-pmap-c)# bandwidth percent 10
Router(config-pmap-c)# exit
Router(config-pmap)# policy-map policy1
Router(config-pmap)# class vlan-customer1
Router(config-pmap-c)# shape 10000000
Router(config-pmap-c)# service-policy child-cust1
!
Router(config)# interface GigabitEthernet 1/0/0.1
Router(config-subif)# encapsulation dot1q 10
Router(config-subif)# interface GigabitEthernet 1/0/0
Router(config-if)# service-policy output policy1
Configuration Examples for VLAN Tag-Based QoS
This section provides the following configuration examples:
• Configuring a VLAN Tag-Based QoS Policy: Example, page 21-14
• Configuring a VLAN Tag-Based QoS Policy: Invalid Configuration Example, page 21-14
Step 9
Router(config-if)# encapsulation dot1q vlan-id
Enables IEEE 802.1Q encapsulation of traffic on the
specified subinterface in a virtual LAN (VLAN
vlan-id is the virtual LAN identifier. The allowed range is
from 1 to 4095. For the IEEE 802.1Q-in-Q VLAN Tag
Termination feature, the first instance of this argument
defines the outer VLAN ID, and the second and
subsequent instances define the inner VLAN ID.
Step 10
Router(config-if)# service-policy [input |
output] policy-map-name
Applies the policy map you specify to the interface.
input indicates to apply the policy to inbound traffic.
output indicates to apply the policy to outbound traffic.
policy-map-name is the name of the policy map that you
want to apply to the traffic class.
