Configuration: QoS (Quality of Service) Configuration
The switch support four QoS queues per port with strict or weighted fair queu-
ing scheduling. There are 24 QoS Control Lists (QCL) for advance program-
mable 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 accor-
ding 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 prio-
rity in the arbitration. The ingress super priority queue allows traffic recogni-
zed as CPU traffic to be received and queued for transmission to the CPU even
when all the QoS class queues are congested.
