Interface QoS 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.

In QoS advanced mode, the device uses policies to support per flow QoS. A
policy and its components have the following characteristics and relationships:
• A policy contains one or more class maps.
• A class map defines a flow with one or more associating ACLs. Packets that
match only ACL rules (ACE) in a class map with Permit (forward) action are
considered belonging to the same flow, and are subjected to the same
