Enabling Vlan-Based Pfc Qos On Layer 2 Lan Ports - Cisco 7609 Configuration Manual

Configuring PFC QoS
This example shows how to disable PFC QoS on the VLAN 5 interface:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface vlan 5
Router(config-if)# no mls qos
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos | begin QoS is disabled
QoS is disabled on the following interfaces:

Enabling VLAN-Based PFC QoS on Layer 2 LAN Ports

Note With DFCs installed, Supervisor Engine 2 does not support VLAN-based PFC QoS.
By default, PFC QoS uses policy maps attached to LAN ports. For ports configured as Layer 2 LAN
ports with the switchport keyword, you can configure PFC QoS to use policy maps attached to a VLAN
(see the
keyword are not associated with a VLAN.
To enable VLAN-based PFC QoS on a Layer 2 LAN port, perform this task:
Command
Step 1
Router(config)# interface {{type
{port-channel number}}
Step 2
Router(config-if)# mls qos vlan-based
Router(config-if)# no mls qos vlan-based
Step 3
Router(config-if)# end
Step 4
Router# show mls qos
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to enable VLAN-based PFC QoS on Fast Ethernet port 5/42:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface fastethernet 5/42
Router(config-if)# mls qos vlan-based
Router(config-if)# end
This example shows how to verify the configuration:
Router# show mls qos | begin QoS is vlan-based
QoS is vlan-based on the following interfaces:
