Usage Guidelines
Use this command to configure the QoS appropriate for VoIP traffic within the QoS domain. The QoS domain
includes the device, the network interior, and edge devices that can classify incoming traffic for QoS.
Auto-QoS configures the device for VoIP with Cisco IP phones on device and routed ports and for 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.
