Usage Guidelines Use this command to configure the QoS that is appropriate for VoIP traffic within the QoS domain. The
QoS domain includes the switch, the interior of the network, and the edge devices that can classify
incoming traffic for QoS.
In releases earlier than Cisco IOS Release 12.2(20)EA2, auto-QoS configures the switch only for VoIP
with Cisco IP Phones on switch ports.
In Cisco IOS Release 12.2(20)EA2 or later, auto-QoS configures the switch for VoIP with Cisco IP
Phones 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, you should enable auto-QoS before you configure other QoS
commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.
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.
