Cisco Systems EA6500 Manual De Usuario

This example shows how to disable PFC QoS on the VLAN 5 interface:

Router# configure terminal 

Enter configuration commands, one per line.  End with CNTL/Z.

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:

    Vl5 

<...Output Truncated...>

Router#

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 

). Ports not configured with the switchport 

keyword are not associated with a VLAN.

To enable VLAN-based PFC QoS on a Layer 2 LAN port, perform this task: 

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.  End with CNTL/Z.

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:

    Fa5/42

<...Output Truncated...>

Router(config)# interface {{type

1

 slot/port} | 

{port-channel number}} 

1.

type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet 

Selects the interface to configure.

Router(config-if)# mls qos vlan-based 

Enables VLAN-based PFC QoS on a Layer 2 LAN port. 

Router(config-if)# no mls qos vlan-based 

Disables VLAN-based PFC QoS. 

Router(config-if)# end 

Exits configuration mode.

Router# show mls qos 

Verifies the configuration.
