2-16 QoS
The switch 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 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.
2-16.1 Port Classification
The section allows you to configure the basic QoS Ingress Classification
settings for all switch ports. and the settings relate to the currently selected
stack unit, as reflected by the page header.
Web Interface
To configure the QoS Port Classification parameters in the web interface:
1. Click Configuration, QoS, Port Classification
2. Scroll to select QoS class, DP Level, PCP and DEI parameters
3. Click the save to save the setting
4. If you want to cancel the setting then you need to click the Reset button.
It will revert to previously saved values
