Interface Settings
The Interface Settings page enables configuring QoS on each port of the device, as follows:
• QoS State Disabled on an Interface—All inbound traffic on the port is mapped to the 
best effort queue and no classification/prioritization takes place.
• QoS State of the Port is Enabled—Port prioritize traffic on ingress is based on the 
system wide configured trusted mode, which is either CoS/802.1p trusted mode or 
DSCP trusted mode. 
To enter QoS settings per interface:
STEP 1 Click Quality of Service > QoS Basic Mode > Interface Settings.
STEP  2 Select Port or LAG to display the list of ports or LAGs. 
QoS State displays whether QoS is enabled on the interface.
STEP  3 Select an interface, and click Edit.
STEP  4 Select the Port or LAG interface.
STEP  5 Click to enable or disable QoS State for this interface.
STEP  6 Click Apply. The Running Configuration file is updated.
