Usage Guidelines
Use this command to configure the QoS appropriate for VoIP traffic within the QoS domain. The QoS
domain includes the switch, the interior of the network, 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, 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.
