QoS Control List Configuration
This page lists the QCEs for a given QCL.
„ Frames can be classified by 4 different QoS classes: Low, Normal, Medium, and High.
„ The classification is controlled by a QoS assigned to each port.
„ A QCL consists of an ordered list of up to 12 QCEs.
„ Each QCE can be used to classify certain frames to a specific QoS class.
„ This classification can be based on parameters such as VLAN ID, UDP/TCP port, IPv4/IPv6 DSCP or Tag Priority.
Frames not matching any of the QCEs are classified to the default QoS Class for the port.
The QoS Control List Configuration screen is shown Figure 4-9-7 .
