Chapter 44      Configuring Quality of Service
Configuring VSS Auto-QoS
Auto qos classify—Generates QoS configuration for untrusted interfaces. It applies a service-policy to 
classify the traffic stemming from untrusted desktops or devices and marks them accordingly. The 
service-policies generated do not police.
Auto-Qos Compact 
When you enter an auto-QoS command, the switch goes on to display all the generated commands as if 
the commands were entered from the CLI. Enable auto-QoS compact if you want to hide auto-QoS 
generated commands from the running configuration.
To enable auto-Qos compact, enter this command:
To disable auto-QoS compact, first remove all the auto-Qos configuration by entering the no form of the 
corresponding auto-QoS interface configuration command and then enter the no auto qos global 
compact global configuration command. Disabling auto-QoS compact is a required task when have to 
perform an ISSU from an image where auto-QoS compact is supported to an image where this feature is 
not available.
The following example shows you how to enable auto-qos compact and configure the auto qos voip 
cisco-phone interface configuration command and then display configuration details:
Switch# configure terminal
Switch(config)# auto qos global compact
Switch(config)# interface GigabitEthernet1/2 
Switch(config-if)# auto qos voip cisco-phone
Switch(config-if)# show auto-qos
GigabitEthernet1/2
auto qos voip cisco-phone 
Command Purpose
Switch# configure terminal
Enters global configuration mode.
Switch(config)# auto qos global 
compact 
Enables auto-Qos compact and generates global auto-Qos 
configurations that are hidden from the running configuration. 
You can then enter the auto-QoS command you want to 
configure, in the interface configuration mode. The interface 
commands that the system generates are also hidden from 
running configuration. 
To display the auto-QoS configuration that has been applied, use 
these the privileged EXEC commands: show derived-config, 
show policy-map, show policy-map interface, show 
class-map, show table-map, and show auto-qos, show ip 
access-list.
