Chapter 25 Bandwidth Management Screens Figure 270 ADVANCED > BW MGMT > Class Setup > Add Sub-Class The following table describes the labels in this screen. Table 146 ADVANCED > BW MGMT > Class Setup > Add Sub-Class LABEL 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 25.1.5 on page 467) 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 469).
