Interface QoS Settings
The Interface Settings page enables configuring QoS on each port of the switch,
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. 1 p trusted mode or DSCP trusted mode.
To enter QoS settings per interface:
Click Quality of Service > QoS Basic Mode > Interface Settings. The Interface
Settings page is displayed.
Select Port or LAG to display the list of ports or LAGs.
The list of ports/LAGs is displayed. QoS State displays whether QoS is enabled
on the interface.
Select an interface, and click Edit. The Edit QoS Interface Settings is displayed.
Select the Port or LAG interface.
Click to enable or disable QoS State for this interface.
Click Apply. The Running Configuration file is updated.
