Item Description

Parent ID Due to the hierarchical characteristic of QoS, classes are classified

into the root class(highest level class) and the leaf class(lowest level

class) and into the parent class and the child class.

If the target class is a child class of another class, set the parent class

in the Parent ID item. Do not set the Parent ID if the target class is the

root class(highest level class physically connected to the device) or the

default class(class including the bandwidth for traffics that do not

belong to a filter).

Priority If several classes compete to occupy leftover bandwidths or if all

classes attempt to occupy excess bandwidth, set the priority so that

the class with the highest priority occupies the bandwidth first.

MTU The Maximum Transmit Unit(MTU) represents the maximum amount of

packets that can be transmitted at a time. It is recommended that this

setting does not exceed the maximum packet size(1504 Byte) of

Ethernet. If this item is not entered, the default value, ‘1500 Byte’, will

be applied.

Rate This is the basic bandwidth needed for setting class for an assigned

bandwidth.

Ceil Maximum value of assigned bandwidth.

Burst Size of data that can be sent by the class.

Cburst Maximum data size that can be sent at a time.

Filter List Sets filtering rules for the class.

Leaf Qdisc

Parameter

Set a desired Qdisc for the Leaf Qdisc parameter when setting the

lowest level class.

Scheduling

Parameter

1/2/3

Changes the bandwidth of the class based on day and hour.

Up to three scheduling parameter can be set.
