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.
Beginning in Cisco IOS Release 12.2(40)SE, the show auto qos command output shows the service
policy information for the Cisco IP phone.
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.
The switch applies the auto-QoS-generated commands as if the commands were entered from the
Note
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.
