Table 17-4 Bandwidth Manager: Edit Class

Use the auto-generated name or enter a descriptive name of up to 20 alphanumeric
characters, including spaces.
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.
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.
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 17.6.1) 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 17-2).
