Figure 4-42. Port QoS configuration.
Parameter description:
Number of Classes: 1/2/4
Port: Users can choose ports (1–8) respectively with Priority Class for Per Port Priority function.
Default Class: Users can set up High Priority or Low Priority for each port respectively.
Low/Normal/Medium/High
QCL: The number of QCL rules 1–24. Each port has to apply one of the QCL rules for QoS behavior.
User priority: The user priority value 0~7 (3 bits) is used as an index to the eight QoS class values for VLAN tagged or priority tagged
frames.
Queuing Mode: There are two Scheduling Methods, Strict Priority and Weighted Fair. The default is Strict Priority. After you choose a
Scheduling Method, click on the Apply button.
Queue Weighted: There are four queues per port and four classes weighted number (1/2/4/8) for each queues. Select the weighted
number when the scheduling method is set to “Weighted Fair” mode.
4.8.2 Qos Control List
Function name: QoS Control List Configuration
Function description: The switch supports four QoS queues per port with strict or weighted fair queuing scheduling. There are 24 QoS
Control Lists (QCL) for advance programmable QoS classification, based on IEEE 802.1p, Ether Type, VID, IPv4/IPv6 DSCP, and
UDP/TCP ports and ranges.
