3-7-2. Qos Control List

Function name:

Qos Control List Configuration

Function description:

The

switch

support four QoS queues per port with strict or weighted fair

queuing scheduling. There are 8 QoS Control Lists (QCL) for advance
programmable QoS classification, based on IEEE 802.1p, Ether Type, VID,
IPv4/IPv6 DSCP and UDP/TCP ports and ranges.

Fig. 3-35

QCE Configuration:

The QCL consists of 8 QoS Control Entries (QCEs) that are searched
from the top of the list to the bottom of the list for a match. The first
matching QCE determines the QoS classification of the frame. The QCE
ordering is therefore important for the resulting QoS classification
algorithm. If no matching QCE is found, the default QoS class is used in
the port QoS configuration.
