17.2.4 Bandwidth Monitor Screen
Use this screen to look at the device’s bandwidth usage and allocation. To access this screen,
click Management > Bandwidth MGMT > Monitor.
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 17.1.7.1 on page 199) 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.)
Application
Select a pre-defined application. If you select a predefined application, do not set
up the other filter criteria.
FTP (File Transfer Program) enables fast transfer of files, including large files that
may not be possible by e-mail. Select this to configure the bandwidth filter for FTP
traffic.
SIP (Session Initiation Protocol) is a signaling protocol used in Internet telephony,
instant messaging, events notification and conferencing. The ZyXEL Device
supports SIP traffic pass-through. Select this to configure this bandwidth filter for
SIP traffic. This makes it easier to manage bandwidth for SIP traffic and is useful,
for example, when there is a VoIP (Voice over Internet Protocol) device on your
LAN.
