DESCRIPTION

Class Configuration

 

 

 

Class Name

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

 

alphanumeric characters, including spaces.

 

 

Bandwidth Budget

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

(kbps)

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 sub-class to borrow bandwidth from its parent

from parent class

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

 

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

 

sub-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 (see Section 19.7.4 on page

 

353) 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 Table 108 on page

 

357).
