Auto-QoS Commands
This chapter contains the following auto-QoS commands:
auto qos classify
To automatically configure quality of service (QoS) classification for untrusted devices within a QoS domain, use the auto qos classify command in interface configuration mode. To return to the default setting, use the no form of this command.
auto qos classify [police]
no auto qos classify [police]
Syntax Description
|
police |
(Optional) Configures QoS policing for untrusted devices. |
Command Default
Auto-QoS classify is disabled on the port.

Usage Guidelines
Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS.
When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to configure the ingress and egress queues.

Auto-QoS configures the switch for connectivity with a trusted interface. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routed ports, the DSCP value of the incoming packet is trusted.
To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.
To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging.

This is the policy map when the auto qos classify police command is configured:
policy-map AUTOQOS-SRND4-CLASSIFY-POLICE-POLICY class AUTOQOS_MULTIENHANCED_CONF_CLASS set dscp af41 police 5000000 8000 exceed-action drop class AUTOQOS_BULK_DATA_CLASS set dscp af11 police 10000000 8000 exceed-action policed-dscp-transmit class AUTOQOS_TRANSACTION_CLASS set dscp af21 police 10000000 8000 exceed-action policed-dscp-transmit class AUTOQOS_SCAVANGER_CLASS set dscp cs1 police 10000000 8000 exceed-action drop class AUTOQOS_SIGNALING_CLASS set dscp cs3 police 32000 8000 exceed-action drop class AUTOQOS_DEFAULT_CLASS set dscp default police 10000000 8000 exceed-action policed-dscp-transmit
 Note | The switch applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (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 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 fail to be applied, the previous running configuration is restored. |
After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface and apply the new policy map.
Note | To disable auto-QoS, you need remove the auto-QoS commands manually. |
To disable auto-QoS on a port, use the no auto qos trust interface configuration command. 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 trust 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).
Examples
This example shows how to enable auto-QoS classification of an untrusted device and police traffic:
Switch(config)# interface gigabitethernet2/0/1 Switch(config-if)# auto qos classify police
You can verify your settings by entering the show auto qos interface interface-id privileged EXEC command.

Note | The switch applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (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 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 fail to be applied, the previous running configuration is restored. |
If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed.
When you enable the auto-QoS feature on the first port, QoS is globally enabled (mls qos global configuration command), and other global configuration commands are added.
After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.
Note | To disable auto-QoS, you need to remove the auto-QoS commands manually. |
To disable auto-QoS on a port, use the no auto qos video interface configuration command. 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 video 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).
Examples
This example shows how to enable auto-QoS for a Cisco Telepresence interface with conditional trust. The interface is trusted only if a Cisco Telepresence device is detected; otherwise, the port is untrusted.
Switch(config)# interface gigabitethernet2/0/1 Switch(config-if)# auto qos video cts
You can verify your settings by entering the show auto qos video interface interface-id privileged EXEC command.

auto qos voip
To automatically configure quality of service (QoS) for voice over IP (VoIP) within a QoS domain, use the auto qos voip command in interface configuration mode. Use the no form of this command to return to the default setting.
auto qos voip { cisco-phone | cisco-softphone | trust}
no auto qos voip { cisco-phone | cisco-softphone | trust}
Syntax Description
|
cisco-phone |
Identifies this port as connected to a Cisco IP Phone, and automatically configures QoS for VoIP. The QoS labels of incoming packets are trusted only when the telephone is detected. |
|
cisco-softphone |
Identifies this port as connected to a device running the Cisco SoftPhone, and automatically configures QoS for VoIP. |
|
trust |
Identifies this port as connected to a trusted switch, and automatically configures QoS for VoIP. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packet is trusted. For routed ports, the DSCP value of the incoming packet is trusted. |
Command Default
Auto-QoS is disabled on the port.
When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, assign packet labels, and configure the ingress and egress queues. For more information, seeTable 1

This command was introduced. |
Usage Guidelines
Use this command to configure the QoS appropriate for VoIP traffic within the QoS domain. The QoS domain includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS.
Auto-QoS configures the switch for VoIP with Cisco IP Phones on switch and routed ports and for VoIP with devices running the Cisco SoftPhone application. These releases support only Cisco IP SoftPhone Version 1.3(3) or later. Connected devices must use Cisco Call Manager Version 4 or later.
To take advantage of the auto-QoS defaults, enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.

If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed.
When you enable the auto-QoS feature on the first port, these automatic actions occur:
- QoS is globally enabled (mls qos global configuration command), and other global configuration commands are added.
- When you enter the auto qos voip cisco-phone interface configuration command on a port at the edge of the network that is connected to a Cisco IP Phone, the switch enables the trusted boundary feature. The switch uses the Cisco Discovery Protocol (CDP) to detect the presence of a Cisco IP Phone. When a Cisco IP Phone is detected, the ingress classification on the port is set to trust the QoS label received in the packet. The switch also uses policing to determine whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the switch changes the DSCP value to 0. When a Cisco IP Phone is absent, the ingress classification is set to not trust the QoS label in the packet. The policing is applied to the traffic that matches the policy-map classification before the switch enables the trust boundary feature.
- When you enter the auto qos voip cisco-softphone interface configuration command on a port at the edge of the network that is connected to a device running the Cisco SoftPhone, the switch uses policing to decide whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the switch changes the DSCP value to 0.
- When you enter the auto qos voip trust interface configuration command on a port connected to the network interior, the switch trusts the CoS value for nonrouted ports or the DSCP value for routed ports in ingress packets (the assumption is that traffic has already been classified by other edge devices).
You can enable auto-QoS on static, dynamic-access, and voice VLAN access, and trunk ports. When enabling auto-QoS with a Cisco IP Phone on a routed port, you must assign a static IP address to the IP phone.
Note | When a device running Cisco SoftPhone is connected to a switch or routed port, the switch supports only one Cisco SoftPhone application per port. |
After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.
To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging.
Note | To disable auto-QoS, you need to remove the auto-QoS commands manually. |
To disable auto-QoS on a port, use the no auto qos voip interface configuration command. 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).

Usage Guidelines
To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. You enable debugging by entering the debug auto qos privileged EXEC command.
The undebug auto qos command is the same as the no debug auto qos command.
When you enable debugging on a switch stack, it is enabled only on the active switch. To enable debugging on a stack member, you can start a session from the active switch by using the session switch-number privileged EXEC command. Then enter the debug command at the command-line prompt of the stack member. You also can use the remote command stack-member-number LINE privileged EXEC command on the active switch to enable debugging on a member switch without first starting a session.
