permitted. A VLAN can be configured as a private VLAN.

QCE

QCE is an acronym for QoS Control Entry. It describes QoS class associated

with a particular QCE ID.

There are six QCE frame types: Ethernet Type, VLAN, UDP/TCP Port, DSCP,

TOS, and Tag Priority. Frames can be classified by one of 4 different QoS

classes: "Low", "Normal", "Medium", and "High" for individual application.

QCL

QCL is an acronym for QoS Control List. It is the list table of QCEs, containing

QoS control entries that classify to a specific QoS class on specific traffic

objects.

Each accessible traffic object contains an identifier to its QCL. The privileges

determine specific traffic object to specific QoS class.

QL In SyncE this is the Quality Level of a given clock source. This is received

on a port in a SSM indicating the quality of the clock received in the port.

QoS

QoS is an acronym for Quality of Service. It is a method to guarantee a

bandwidth relationship between individual applications or protocols.

A communications network transports a multitude of applications and data,

including high-quality video and delay-sensitive data such as real-time voice.

Networks must provide secure, predictable, measurable, and sometimes

guaranteed services.

Achieving the required QoS becomes the secret to a successful end-to-end

business solution. Therefore, QoS is the set of techniques to manage network

resources.

There are 4 web-pages associated with the QoS configuration:

QoS|QoS Control List: The web page shows the QCEs in a prioritized way,

highest (top) to lowest (bottom). Default the table is empty. An ingress frame

will only get a hit on one QCE even though there are more matching QCEs. The

first matching QCE will give that frame a priority: Low, Normal, Medium or

High. 5 different QCLs can be created, each with 8 different QCEs. You assign

each port a QCL id under QoS|Ports page. The QoS counters can be viewed

under Monitor|Ports|QoS statistics. There are number of parameters that can be

configured with a QCE. Read the Web page help text to get further information

for each of them.

QoS|Ports: The Ports QoS page is used to assign a QCL id to an ingress port.
