Use the QoS Control List Configuration page to configure Quality of Service
policies for handling ingress packets based on Ethernet type, VLAN ID,
TCP/UDP port, DSCP, ToS, or VLAN priority tag.
Once a QCE is mapped to a port, traffic matching the first entry in the QoS
Control List is assigned to the QoS class, drop precedence level, and DSCP
value defined by that entry. Traffic not matching any of the QCEs are
classified to the default QoS Class for the port.
