Attaching Qos Service Policies To Physical Interfaces With Vlan Subinterfaces - Cisco 10000 Series Configuration Manual

Attaching Virtual LAN QoS Service Policies

Attaching QoS Service Policies to Physical Interfaces with VLAN Subinterfaces

To attach QoS service policies to physical interfaces with VLAN subinterfaces, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# interface type
slot/module/port
Step 2
Router(config-if)# service-policy {input
| output} policy-map-name
Step 3
Router(config-if)# interface type
slot/module/port.subinterface
Step 4
Router(config-subif)# encapsulation dot1q
vlanid
Configuration Example for Attaching QoS Policies to Physical Interfaces with VLAN Subinterfaces
Example 4-13
interface 1/0/0 for inbound traffic. VLAN 4, configured on the GigabitEthernet subinterface 1/0/0.3,
inherits the service policy of the physical Gigabit Ethernet interface 1/0/0.
Example 4-13 Attaching a QoS Policy to a VLAN Interface
Router(config)# interface GigabitEthernet 1/0/0
Router(config-if)# service-policy input myQoS
Router(config-if)# interface GigabitEthernet 1/0/0.3
Router(config-subif)# encapsulation dot1q 4

Purpose
Specifies the physical Ethernet interface to which you want to
attach the QoS service policy. Enters interface configuration
mode.
Attaches the service policy you specify to the physical interface.
input indicates to apply the service policy to inbound traffic on
the interface.
output indicates to apply the service policy to outbound traffic on
the interface.
Note
policy-map-name is the name of the policy map.
Creates a subinterface and enters subinterface configuration
mode.
Configures the subinterface as a VLAN subinterface.
dot1q defines the encapsulation format as IEEE 802.1Q VLAN.
vlanid is a number that identifies the VLAN.
Note
shows how to attach a service policy named myQoS to the physical Gigabit Ethernet
For QoS policies containing the bandwidth, priority,
random-detect, queue-limit, and shape commands, you
must specify the output keyword. If you use these
commands with the input keyword, the router ignores the
commands.
The router applies the service policy of the physical
interface to all of the individual VLANs configured on the
interface.
