Mode section.

Configuring QoS Properties
Use the QoS Properties page to configure the QoS mode for the switch, and 
define the default CoS priority for each interface.
To select the QoS mode and define the default CoS priority for each interface:
STEP 1 Click Quality of Service > General > QoS Properties. 
STEP  2 Select the QoS mode (basic, advanced, or disabled) that will be active on the 
switch. 
STEP  3 Click Apply. The QoS mode is defined, and the Running Configuration is updated. 
STEP  4 The Interface CoS Configuration Table displays the default CoS value for each 
interface. To modify the interface’s default CoS value, select the desired interface 
and click Edit. 
STEP  5 Enter the following information: 
• Interface—Select the interface to be configured.
• Default CoS—Select the default CoS value to be assigned for incoming 
packets (that do not have a VLAN tag). The range is 0 to 7.
The default CoS value is applicable only if the switch is in QoS basic mode 
and CoS/802.1p is the trusted mode.
