QoS
The AS Series switches support four QoS queues per port with strict or weighted fair queuing
scheduling. It supports 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 priority to the frame according to what was
configured for that specific QoS class.
The AS Series switches support advanced memory control mechanisms providing excellent
performance of all QoS classes under any traffic scenario, including jumbo frames. 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.
