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