Consolidated Platform Configuration Guide, Cisco IOS 15.2(6)E (Catalyst 2960-XR Switch)

Prerequisites for Auto-QoS

Before configuring standard QoS or auto-QoS, you must have a thorough understanding of these items:

The types of applications used and the traffic patterns on your network.
Traffic characteristics and needs of your network. Is the traffic bursty? Do you need to reserve bandwidth for voice and video streams?
Bandwidth requirements and speed of the network.
Location of congestion points in the network.

Auto-QoS VoIP Considerations

Before configuring auto-QoS for VoIP, you should be aware of this information:

Auto-QoS configures the switch for VoIP with Cisco IP Phones on nonrouted and routed ports. Auto-QoS also configures the switch for VoIP with devices running the Cisco SoftPhone application.

Note

When a device running Cisco SoftPhone is connected to a nonrouted or routed port, the switch supports only one Cisco SoftPhone application per port.

When enabling auto-QoS with a Cisco IP Phone on a routed port, you must assign a static IP address to the IP phone.
This release supports only Cisco IP SoftPhone Version 1.3(3) or later.
Connected devices must use Cisco Call Manager Version 4 or later.
Auto-Qos VoIP uses the priority-queue interface configuration command for an egress interface. You can also configure a policy-map and trust device on the same interface for Cisco IP phones.

Auto-QoS Enhanced Considerations

Auto-QoS is enhanced to support video. Automatic configurations are generated that classify and trust traffic from Cisco TelePresence systems and Cisco IP cameras.

Before configuring auto-QoS enhanced, you should be aware of this information:

The auto qos srnd4 global configuration command is generated as a result of enhanced auto-QoS configuration.

Restrictions for Auto-QoS

The following are restrictions for automatic QoS (auto-QoS):

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 this new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map to the interface.
To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. If necessary, you can fine-tune the QoS configuration, but we recommend that you do so only after the auto-QoS configuration is completed.
By default, the CDP is enabled on all ports. For auto-QoS to function properly, do not disable CDP.

Note

You can enable auto-QoS on static, dynamic-access, voice VLAN access, and trunk ports.

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. It uses the egress queues instead of using the default (disabled) QoS behavior. The switch offers best-effort service to each packet, regardless of the packet contents or size, and sends it from a single queue.

When you enable auto-QoS, it automatically classifies traffic based on the traffic type and ingress packet label. The switch uses the classification results to choose the appropriate egress queue.

You can use auto-QoS commands to identify ports connected to the following Cisco devices:

Cisco IP Phones
Devices running the Cisco SoftPhone application
Cisco TelePresence
Cisco IP Camera
Cisco digital media player

You also use the auto-QoS commands to identify ports that receive trusted traffic through an uplink. Auto-QoS then performs these functions:

Detects the presence or absence of auto-QoS devices through conditional trusted interfaces.
Configures QoS classification
Configures egress queues

Auto-QoS Compact Overview

When you enter an auto-QoS command, the switch displays all the generated commands as if the commands were entered from the CLI. You can use the auto-QoS compact feature to hide the auto-QoS generated commands from the running configuration. This would make it easier to comprehend the running-configuration and also help to increase efficient usage of memory.

Generated Auto-QoS Configuration

By default, auto-QoS is disabled on all ports. Packets are not modified--the CoS, DSCP and IP precedence values in the packet are not changed.

When you enable the auto-QoS feature on the first port of the interface:

Ingress packet label is used to categorize traffic, to assign packet labels, and to configure the ingress and egress queues.
QoS is globally enabled (mls qos global configuration command), and other global configuration commands are automatically generated. (See Examples: Global Auto-QoS Configuration).
Switch enables the trusted boundary feature and uses the Cisco Discovery Protocol (CDP) to detect the presence of a supported device.
Policing is used to determine whether a packet is in or out of profile and specifies the action on the packet.

VoIP Device Specifics

The following actions occur when you issue these auto-QoS commands on a port:

auto qos voip cisco-phone —When you enter this command on a port at the network edge connected to a Cisco IP Phone, the switch enables the trusted boundary feature. 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 there is no Cisco IP Phone, the ingress classification is set to not trust the QoS label in the packet. The policing is applied to the traffic matching the policy-map classification before the switch enables the trust boundary feature.
auto qos voip cisco-softphone —When you enter this interface configuration command on a port at the network edge that is connected to a device running the Cisco SoftPhone, the switch 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.
auto qos voip trust —When you enter this 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).

The switch configures egress queues on the port according to the settings in the following tables.

Table 1. Traffic Types, Packet Labels, and Queues
	VoIP Data Traffic	VoIP Control  Traffic	Routing Protocol Traffic	STP BPDU Traffic	Real-Time Video Traffic	All Other Traffic
DSCP value	46	24, 26	48	56	34	–
CoS value	5	3	6	7	3	–
CoS-to-Egress queue map	4, 5  (queue 1)	2, 3, 6, 7 (queue 2)			0 (queue 3)	2 (queue 3)	0, 1  (queue 4)

The following table shows the generated auto-QoS configuration for the egress queues.

Table 2. Auto-QoS Configuration for the Egress Queues
Egress Queue	Queue Number	CoS-to-Queue Map	Queue Weight (Bandwidth)	Queue (Buffer) Size for Gigabit-Capable Ports	Queue (Buffer) Size for 10/100 Ethernet Ports
Priority	1	4, 5	Up to 100 percent	25 percent	15 percent
SRR shared	2	2, 3, 6, 7	10 percent	25 percent	25 percent
SRR shared	3	0	60 percent	25 percent	40 percent
SRR shared	4	1	20 percent	25 percent	20 percent

When you enable auto-QoS by using the auto qos voip cisco-phone , the auto qos voip cisco-softphone , or the auto qos voip trust interface configuration command, the switch automatically generates a QoS configuration based on the traffic type and ingress packet label and applies the commands listed in Examples: Global Auto-QoS Configuration to the port.

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.

Effects of Auto-Qos Compact on Running Configuration

If auto-QoS compact is enabled:

Only the auto-QoS commands entered from the CLI are displayed in running-config.
The generated global and interface configurations are hidden.
When you save the configuration, only the auto-qos commands you have entered are saved (and not the hidden configuration).
When you reload the switch, the system detects and re-executes the saved auto-QoS commands and the AutoQoS SRND4.0 compliant config-set is generated .

Note

Do not make changes to the auto-QoS-generated commands when auto-QoS compact is enabled, because user-modifications are overridden when the switch reloads.

When auto-qos global compact is enabled:

show derived-config command can be used to view hidden AQC derived commands.
AQC commands will not be stored to memory. They will be regenerated every time the switch is reloaded.
When compaction is enabled, auto-qos generated commands should not be modified .
If the interface is configured with auto-QoS and if AQC needs to be disabled, auto-qos should be disabled at interface level first.

Enabling Auto-Qos Compact

To enable auto-Qos compact, enter this command:

SUMMARY STEPS

configure terminal
auto qos global compact

DETAILED STEPS

Command or Action Purpose

	Command or Action	Purpose
Step 1	configure terminal Example: `Device# configure terminal`	Enters global configuration mode.
Step 2	auto qos global compact Example: `Device(config)# auto qos global compact`	Enables auto-Qos compact and generates (hidden) the global configurations for auto-QoS. You can then enter the auto-QoS command you want to configure in the interface configuration mode and the interface commands that the system generates are also hidden. To display the auto-QoS configuration that has been applied, use these the privileged EXEC commands: show derived-config show policy-map show access-list show class-map show table-map show auto-qos show policy-map interface show ip access-lists These commands will have keyword "AutoQos- ".

Step 1

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 2

auto qos global compact

Example:


Device(config)# auto qos global compact

Enables auto-Qos compact and generates (hidden) the global configurations for auto-QoS.

You can then enter the auto-QoS command you want to configure in the interface configuration mode and the interface commands that the system generates are also hidden.

To display the auto-QoS configuration that has been applied, use these the privileged EXEC commands:

show derived-config
show policy-map
show access-list
show class-map
show table-map
show auto-qos
show policy-map interface
show ip access-lists

These commands will have keyword "AutoQos- ".

What to do next

To disable auto-QoS compact, remove auto-Qos instances from all interfaces by entering the no form of the corresponding auto-QoS commands and then enter the no auto qos global compact global configuration command.

Troubleshooting Auto-QoS

To display the QoS commands that are automatically generated when auto-QoS is enabled or disabled, enter the debug auto qos privileged EXEC command before you enable auto-QoS. 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 .

Note

Auto-QoS generated global commands can also be removed manually if desired.

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).

You can use the no mls qos global configuration command to disable the auto-QoS-generated global configuration commands. With QoS disabled, there is no concept of trusted or untrusted ports because the packets are not modified (the CoS, DSCP, and IP precedence values in the packet are not changed). Traffic is switched in pass-through mode (packets are switched without any rewrites and classified as best effort without any policing).
