QoS
The switch supports 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.
The switch offers 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. The QoS control list (QCL) implements the QoS
classification mechanism. 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 also supports advanced memory control mechanisms providing excellent performance of all
QoS classes under any traffic scenario, including jumbo frame. 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.
4.15.1 Port Classification
The section enables configuring the basic QoS Ingress Classification settings for all switch ports.
To configure the QoS Port Classification parameters via the web interface:
1. Navigate to Configuration > QoS > Port Classification .
2. Use the drop-down menu to set the various port parameters.
3. Click
Apply or click Reset to cancel changes and revert to previously saved values. 0.
