3. Create a QoS profile which associates a service level and a classifier.
4. Apply a QoS profile to a port(s).
4.8.2 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 in Figure 4-8-1 appears.

The page includes the following fields:
Object Description
• QCL #
Select a QCL to display a table that lists all the QCEs for that particular QCL.
• QCE Type
Specifies which frame field the QCE processes to determine the QoS class of the
frame.The following QCE types are supported:
•
Ethernet Type: The Ethernet T
ype field. If frame is tagged, this is the
Ethernet Type that follows the tag header.
• VLAN ID: VLAN ID. Only
applicable if the frame is VLAN tagged.
• TCP/UDP Port: IPv4 TCP/UDP source/destination port.
• DSCP: IPv4 and IPv6 DSCP.
•
ToS: The 3 precedence bit in the ToS byte of the IPv4/IPv6 header (also
known
as DS field).
• Tag Priority: User Priority. Only applicable if the frame is VLAN tagged or
priority ta
gged.
