Table 58 Media Bandwidth Management: Class Configuration
LABEL 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
from parent class
Select this option to allow a child-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 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.
