See Appendix H on page 283 for examples of services for which you might create bandwidth
classes. Each field is described in the following table.
Table 72 Management > Bandwidth MGMT > Class Setup > Edit
LABEL DESCRIPTION
This section lets you set the budget and priority for this class.
Class Name Finish the auto-generated name, or enter a descriptive name up to 20
alphanumeric characters long. Spaces are allowed.
Bandwidth Budget Enter the maximum bandwidth for the class, in kbps. The recommendation is 20 -
20000 kbps for each class.
Priority Enter the priority of this class. The higher the number, the higher the priority. Legal
values are 0 - 7. 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 15.1.7.1 on page 155 ) 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 Bandwidth Management Summary
Screen ).
This section lets you set criteria that are used to identify which traffic is managed
in this class and which traffic is not managed in this class. If you leave the default
value in a field, there is no restriction for that criteria.
Enable Bandwidth
Filter
Select this if you want the ZyXEL Device to use at least one of the following filter
criteria when it manages bandwidth. You must enter a value in at least one of the
following fields. (The Subnet Mask fields are only available when you enter the
destination or source IP address.)
