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 inbound traffic
for QoS.
In releases earlier than Cisco IOS Release 12.2(25)EY, auto-QoS configures the switch only for VoIP
with Cisco IP Phones on switch ports.
In Cisco IOS Release 12.2(25)EY or later, 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.
