Configuring Auto-QoS

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http:/​/​www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites for Auto-QoS

The prerequisites for auto-QoS are the same as the prerequisites for standard QoS.

Restrictions for Auto-QoS

The following are restrictions for auto-QoS:

  • Auto-qos is not supported on SVI interfaces.
  • Auto-qos is not supported on interfaces which are bundled in an EtherChannel.
  • The trust device device_type interface configuration command is only supported in an auto-QoS configuration, and not as a stand-alone command on the switch. When using the trust device device_type interface configuration command in an auto-QoS configuration, if the connected peer device is not a corresponding device (defined as a device matching your trust policy), both CoS and DSCP values are set to "0" and any input policy will not take effect.
  • When upgrading your software release from a pre- 3.2.2 software version to a 3.2.2 or later software version, you must follow the auto-QoS upgrade procedure described in this chapter.

Information About Configuring Auto-QoS

Auto-QoS Overview

You can use the auto-QoS feature to simplify the deployment of QoS features. Auto-QoS determines the network design and enables QoS configurations so that the switch can prioritize different traffic flows.

The switch employs the MQC model. This means that instead of using certain global configurations, auto-QoS applied to any interface on a switch configures several global class maps and policy maps.

Auto-QoS matches traffic and assigns each matched packet to qos-groups. This allows the output policy map to put specific qos-groups into specific queues, including into the priority queue.

QoS is needed in both directions, both on inbound and outbound. When inbound, the switch port needs to trust the DSCP in the packet (done by default). When outbound, the switch port needs to give voice packets "front of line" priority. If voice is delayed too long by waiting behind other packets in the outbound queue, the end host drops the packet because it arrives outside of the receive window for that packet.

Auto-QoS Global Configuration Templates

In general, an auto-QoS command generates a series of class maps that either match on ACLs or on DSCP and/or CoS values to differentiate traffic into application classes. An input policy is also generated, which matches the generated classes and in some cases, polices the classes to a set bandwidth. Eight egress-queue class maps are generated. The actual egress output policy assigns a queue to each one of these eight egress-queue class maps.

The auto-QoS commands only generate templates as needed. For example, the first time any new auto-QoS command is used, global configurations that define the eight queue egress service-policy are generated. From this point on, auto-QoS commands applied to other interfaces do not generate templates for egress queuing because all auto-QoS commands rely on the same eight queue models, which have already been generated from the first time a new auto-QoS command was used.

Auto-QoS Policy and Class Maps

After entering the appropriate auto-QoS command, the following actions occur:

  • Specific class maps are created.
  • Specific policy maps (input and output) are created.
  • Policy maps are attached to the specified interface.
  • Trust level for the interface is configured.

Effects of Auto-QoS on Running Configuration

When auto-QoS is enabled, the auto qos interface configuration commands and the generated global configuration are added to the running configuration.

The switch applies the auto-QoS-generated commands as if the commands were entered from the CLI. An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions may occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the switch without saving the current configuration to memory. If the generated commands are not applied, the previous running configuration is restored.

How to Configure Auto-QoS

Configuring Auto-QoS (CLI)

For optimum QoS performance, configure auto-QoS on all the devices in your network.

SUMMARY STEPS

    1.    configure terminal

    2.    interface interface-id

    3.    Depending on your auto-Qos configuration, use one of the following commands:

    • auto qos voip { cisco-phone | cisco-softphone | trust}
    • auto qos video { cts | ip-camera | media-player}
    • auto qos classify [ police]
    • auto qos trust { cos | dscp}

    4.    end

    5.    show auto qos interface interface-id


DETAILED STEPS
      Command or Action Purpose
    Step 1 configure terminal


    Example:
    
                
                
    Switch# configure terminal
    
    
     

    Enters the global configuration mode.

     
    Step 2 interface interface-id


    Example:
    
                
                
    Switch(config)# interface gigabitethernet 3/0/1
    
    
     

    Specifies the port that is connected to a VoIP port, video device, or the uplink port that is connected to another trusted switch or router in the network interior, and enters the interface configuration mode.

     
    Step 3 Depending on your auto-Qos configuration, use one of the following commands:
    • auto qos voip { cisco-phone | cisco-softphone | trust}
    • auto qos video { cts | ip-camera | media-player}
    • auto qos classify [ police]
    • auto qos trust { cos | dscp}


    Example:
    Switch(config-if)# auto qos trust dscp
    
    
     

    The following commands enable auto-QoS for VoIP:

    • auto qos voip cisco-phone—If the port is connected to a Cisco IP Phone, the QoS labels of incoming packets are only trusted (conditional trust through CDP) when the telephone is detected.
    • auto qos voip cisco-softphone—The port is connected to device running the Cisco SoftPhone feature. This command generates a QoS configuration for interfaces connected to PCs running the Cisco IP SoftPhone application and mark, as well as police traffic coming from such interfaces. Ports configured with this command are considered untrusted.
    • auto qos voip trust—The uplink port is connected to a trusted switch or router, and the VoIP traffic classification in the ingress packet is trusted.

    The following commands enable auto-QoS for the specified video device (system, camera, or media player):

    • auto qos video cts—A port connected to a Cisco Telepresence system. QoS labels of incoming packets are only trusted (conditional trust through CDP) when a Cisco TelePresence is detected.
    • auto qos video ip-camera—A port connected to a Cisco video surveillance camera. QoS labels of incoming packets are only trusted (conditional trust through CDP) when a Cisco camera is detected.
    • auto qos video media-player—A port connected to a CDP-capable Cisco digital media player. QoS labels of incoming packets are only trusted (conditional trust through CDP) when a digital media player is detected.

    The following command enables auto-QoS for classification:

    • auto qos classify police— This command generates a QoS configuration for untrusted interfaces. The configuration places a service-policy on the interface to classify traffic coming from untrusted desktops/devices and mark them accordingly. The service-policies generated do police.

    The following commands enable auto-QoS for trusted interfaces:

    • auto qos trust cos—Class of service.
    • auto qos trust dscp—Differentiated Services Code Point.
    • <cr>—Trust interface.
     
    Step 4 end


    Example:
    
                
                
    Switch(config-if)# end
    
    
     

    Returns to privileged EXEC mode.

     
    Step 5 show auto qos interface interface-id


    Example:
    
                
                
    Switch# show auto qos interface gigabitethernet 3/0/1
    
    
     

    (Optional) Verifies your entries.

    This command displays the auto-QoS command on the interface on which auto-QoS was enabled. You can use the show running-config privileged EXEC command to display the auto-QoS configuration and the user modifications.

     

    Upgrading Auto-QoS (CLI)

    This procedure should only be followed when upgrading your software release from a pre- 3.2.2 software version to a 3.2.2 or later software version.

    Before You Begin

    Prior to upgrading, you need to remove all auto-QoS configurations currently on the switch. This sample procedure describes that process.

    After following this sample procedure, you must then reboot the switch with the new or upgraded software image and reconfigure auto-QoS.

    SUMMARY STEPS

      1.    show auto qos

      2.    no auto qos

      3.    show running-config | i autoQos

      4.    no policy-map policy-map_name

      5.    show running-config | i AutoQoS

      6.    show auto qos

      7.    write memory


    DETAILED STEPS
      Step 1   show auto qos


      Example:
      Switch# show auto qos
      
      GigabitEthernet2/0/3
      auto qos voip cisco-phone
      
      GigabitEthernet2/0/27
      auto qos voip cisco-softphone
      
      

      In privileged EXEC mode, record all current auto QoS configurations by entering this command.

      Step 2   no auto qos


      Example:
      Switch(config-if)#no auto qos
      
      

      In interface configuration mode, run the appropriate no auto qos command on each interface that has an auto QoS configuration.

      Step 3   show running-config | i autoQos


      Example:
      Switch# show running-config | i autoQos
      
      

      Return to privileged EXEC mode, and record any remaining auto QoS maps class maps, policy maps, access lists, table maps, or other configurations by entering this command.

      Step 4   no policy-map policy-map_name


      Example:
      Switch)config# no policy-map pmap_101
      Switch)config# no class-map cmap_101
      Switch)config# no ip access-list extended AutoQos-101
      Switch)config# no table-map 101
      Switch)config# no table-map policed-dscp
      
      

      In global configuration mode, remove the QoS class maps, policy maps, table maps, and any other auto QoS configurations by entering these commands:

      • no policy-map policy-map-name
      • no class-map class-map-name
      • no ip access-list extended Auto-QoS-x
      • no table-map table-map-name
      • no table-map policed-dscp

      Step 5   show running-config | i AutoQoS


      Example:
      Switch# show running-config | i AutoQos
      
      

      Return to privileged EXEC mode, run this command again to ensure that no auto-QoS configuration or remaining parts of the auto-QoS configuration exists

      Step 6   show auto qos


      Example:
      Switch# show auto qos
      
      

      Run this command to ensure that no auto-QoS configuration or remaining parts of the configuration exists.

      Step 7   write memory


      Example:
      Switch# write memory
      
      

      Write the changes to the auto QoS configuration to NV memory by entering the write memory command.


      What to Do Next

      Reboot the switch with the new or upgraded software image.

      After rebooting with the new or upgraded software image, re-configure auto-QoS for the appropriate switch interfaces as determined by running the show auto qos command described in step 1.


      Note


      There is only one table-map for exceed and another table-map for violate markdown per switch or stack. If the switch already has a table-map under the exceed action, then the auto-qos policy cannot be applied.

      Monitoring Auto-QoS

      Table 1 Commands for Monitoring Auto-QoS

      Command

      Description

      show auto qos [ interface [ interface-id]]

      Displays the initial auto-QoS configuration.

      You can compare the show auto qos and the show running-config command output to identify the user-defined QoS settings.

      show running-config

      Displays information about the QoS configuration that might be affected by auto-QoS.

      You can compare the show auto qos and the show running-config command output to identify the user-defined QoS settings.

      Troubleshooting Auto-QoS

      To troubleshoot auto-QoS, use the debug auto qos privileged EXEC command. For more information, see the debug auto qos command in the command reference for this release.

      To disable auto-QoS on a port, use the no form of the auto qos command interface configuration command, such as no auto qos voip. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos voip command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration).
