12-14 Bandwidth Management
Table 12-4 Bandwidth Manager: Class Configuration
LABEL DESCRIPTION
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 (see
12.6.1 ) 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 12-2 ).
