CONFIGURING QOS
CONTROL LISTS
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. Each list may consist of up
to 24 entries, and can be mapped to a specific port using the Port QoS
Configuration menu (page 185).
Once a QCL is mapped to a port, traffic matching the first entry in the QCL
is assigned to the traffic class (Low, Medium, Normal or High) defined by
that entry. Traffic not matching any of the QCEs are classified to the default
QoS Class for the port.
