DESCRIPTION

 

 

Class Name

Use the auto-generated name or enter a descriptive name of up to 20

 

alphanumeric characters, including spaces.

BW Budget (kbps)

Specify the maximum bandwidth allowed for the class in kbps. The

 

recommendation is a setting between 20 kbps and 20000 kbps for an individual

 

class.

Priority

Enter a number between 0 and 7 to set the priority of this class. The higher the

 

number, the higher the priority. The default setting is 3.

Borrow bandwidth

Select this option to allow a child-class to borrow bandwidth from its parent class

from parent class

if the parent class is not using up its bandwidth budget.

 

Bandwidth borrowing is governed by the priority of the child-classes. That is, a

 

child-class with the highest priority (7) is the first to borrow bandwidth from its

 

parent class.

 

Do not select this for the classes directly below the root class if you want to leave

 

bandwidth available for other traffic types or you want to set the interface’s

 

speed to match what the next device in network can handle (see the Speed field

 

description in the Summary screen).

Bandwidth Filter

The Prestige uses a bandwidth filter to identify the traffic that belongs to a bandwidth class.
