Auto-QoS is not always a very good way of doing QoS, but at least it's
very easy. On SXI it's something like:

Switch(config)# do show run int gi4/24
Building configuration...

Current configuration : 62 bytes
!
interface GigabitEthernet4/24
 no ip address
 shutdown
end

Switch(config)# interface gi4/24
Switch(config-if)# switchport
Switch(config-if)# auto qos voip cisco-phone
(loads of messages)
Switch(config-if)#
Switch(config-if)# do show run int gi4/24
Building configuration...

Current configuration : 931 bytes
!
interface GigabitEthernet4/24
 switchport
 shutdown

 auto qos voip cisco-phone 
end

Switch(config)#

Please test this in a lab first, and verify that the configuration suits
your needs. And be aware that there are a lot of considerations
regarding port-groups and QoS on neighboring ports.
