DESCRIPTION

 

 

Borrow bandwidth

Select this option to allow a sub-class to borrow bandwidth from its parent class if

from parent class

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 207) 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

Select this if you want the ZyXEL Device to use at least one of the following filter

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.

Destination IP

Enter the destination IP address.

Address

 

Destination

This field is effective if you specify a Destination IP Address.

Subnet Mask

Enter the destination subnet mask.

 

 

 

Destination Port

Enter the destination port number.

 

 

Source IP Address

Enter the source IP address.

 

 

Source Subnet

This field is effective if you specify a Source IP Address.

Mask

Enter the source subnet mask.

 

 

 

Source Port

Enter the source port number.

 

 

Protocol ID

Enter the IP protocol number (service type); for example, 1 for ICMP, 6 for TCP or

 

17 for UDP.

Apply

Click this to save your changes and to apply them to the ZyXEL Device.

 

 

Cancel

Click this to set every field in this screen to its last-saved value.
