QoS Control List
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.
Label
Description
QCL#
Select a QCL to display a table that lists all the QCEs for that particular QCL.
QCE Type
Specifies which frame fields the QCE processes to determine the QoS class of the frame.
The following QCE types are supported:
Ethernet Type: The Ethernet Type 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 tagged.
Type Value
Indicates the value according to its QCE type.
Ethernet Type: The field shows the Ethernet Type value.
VLAN ID: The field shows the VLAN ID.
TCP/UDP Port: The field shows the TCP/UDP port range.
DSCP: The field shows the IPv4/IPv6 DSCP value.
Traffic Class
The QoS class associated with the QCE.
Modification
Buttons
You can modify each QCE in the table using the following buttons:
+ : Inserts a new QCE before the current row.
e : Edits the QCE.
Ó
: Moves the QCE up the list.
Ô
: Moves the QCE down the list.
× : Deletes the QCE.
+ : The lowest plus sign adds a new entry at the bottom of the list of QCL.
