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:
