Rule Configuration

Active

Select this to have the ZyXEL Device apply this bandwidth management rule. 
Enable a bandwidth management rule to give traffic that matches the rule priority 

over traffic that does not match the rule.
Enabling a bandwidth management rule also allows you to control the maximum 

amounts of bandwidth that can be used by traffic that matches the rule.

Rule Name 

Use the auto-generated name or enter a descriptive name of up to 20 

alphanumeric characters, including spaces.

BW Budget

Specify the maximum bandwidth allowed for the rule in kbps. The 

recommendation is a setting between 20 kbps and 20000 kbps for an individual 

rule.

Priority

Select a priority from the drop down list box. Choose High, Mid or Low. 

Use All Managed 

Bandwidth

Select this option to allow a rule to borrow unused bandwidth on the interface. 
Bandwidth borrowing is governed by the priority of the rules. That is, a rule with 

the highest priority is the first to borrow bandwidth. Do not select this if you want 

to leave bandwidth available for other traffic types or if you want to restrict the 

amount of bandwidth that can be used for the traffic that matches this rule.

Filter Configuration

Service

This field simplifies bandwidth class configuration by allowing you to select a 

predefined application. When you select a predefined application, you do not 

configure the rest of the bandwidth filter fields (other than enabling or disabling 

the filter).
SIP (Session Initiation Protocol) is a signaling protocol used in Internet 

telephony, instant messaging and other VoIP (Voice over IP) applications. Select 

VoIP(SIP) from the drop-down list box to configure this bandwidth filter for traffic 

that uses SIP. 
File Transfer Protocol (FTP) is an Internet file transfer service that operates on 

the Internet and over TCP/IP networks. A system running the FTP server accepts 

commands from a system running an FTP client. The service allows users to 

send commands to the server for uploading and downloading files. Select FTP 

from the drop-down list box to configure this bandwidth filter for FTP traffic. 
Select User defined from the drop-down list box if you do not want to use a 

predefined application for the bandwidth class. When you select User defined, 

you need to configure at least one of the following fields (other than the Subnet 

Mask fields which you only enter if you also enter a corresponding destination or 

source IP address).

Destination Address Enter the destination IP address in dotted decimal notation.

Destination Subnet 

Netmask

Enter the destination subnet mask. This field has no effect if you do not specify a 

Destination Address. Refer to the appendices for more information on IP 

subnetting.

Destination Port

Enter the port number of the destination.A blank destination IP address means 

any destination IP address.

Source Address

Enter the source IP address in dotted decimal notation. A blank source IP 

address means any source IP address.

Source Subnet 

Netmask

Enter the destination subnet mask. This field has no effect if you do not specify a 

Source Address. Refer to the appendices for more information on IP subnetting. 

A blank source port means any source port number.
