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 supports 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.
3.14.1 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 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. Select QoS class, DP Level, PCP and DEI parameters
3. Click Apply 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

Parameter description:
Port:
The port number for which the configuration below applies.
QoS class:
Controls the default QoS class, i.e., the QoS class for frames not classified in any other way. There is a one to one mapping
between QoS class, queue and priority. A QoS class of 0 (zero) has the lowest priority.
DP level:
Controls the default DP level, i.e., the DP level for frames not classified in any other way.
PCP:
Controls the default PCP for untagged frames.
