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

(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

from parent class

Select this option to allow a sub-class to borrow bandwidth from its parent 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 25.7.4 on page

405

) 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 141 on page

409

).
