3-6. QoS(Quality of Service) Configuration
The
switch
support 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, Ethertype, VID, IPv4/IPv6
DSCP and UDP/TCP ports and ranges.
High flexibility in the classification of incoming frames to a QoS class. The
QoS classification looks for information up to Layer 4, including IPv4 and IPv6
DSCP, IPv4 TCP/UDP port numbers, and user priority of tagged frames. This QoS
classification mechanism is implemented in a QoS control list (QCL). The QoS class
assigned to a frame is used throughout the device for providing queuing, scheduling,
and congestion control guarantees to the frame according to what was configured
for that specific QoS class.
The switch support advanced memory control mechanisms providing
excellent performance of all QoS classes under any traffic scenario, including jumbo
frame. A super priority queue with dedicated memory and strict highest priority in
the arbitration. The ingress super priority queue allows traffic recognized as CPU
traffic to be received and queued for transmission to the CPU even when all the
QoS class queues are congested.
3-6-1. Ports
Function name:
Port QoS Configuration
Function description:
To configure each port QoS behavior. Four QoS queue 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, Ethertype,
VID, IPv4/IPv6 DSCP and UDP/TCP ports and ranges.
Parameter description:
Number of Classes:
1 / 2 / 4
Port:
User can choose the port (1~24) respectively with Priority Class on Per
Port Priority function.
Default Class:
User can set up High Priority or Low Priority for each port respectively.
Low / Normal / Medium / High
QCL:
The number of QCL rule 1~24, each port have to apply one of the QCL
rule for QoS behavior
User priority:
The user priority value 0~7 (3 bits) is used as an index to the eight QoS
