Chapter 21 Bandwidth Management

P-2602H(W)(L)-DxA User’s Guide

See 

 for a list of commonly-used services. The following table 

describes the labels in this screen.  

Table 123   Bandwidth Management Rule Configuration

Rule Configuration

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 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. 
H.323 is a standard teleconferencing protocol suite that provides audio, data 

and video conferencing. It allows for real-time point-to-point and multipoint 

communication between client computers over a packet-based network that 

does not provide a guaranteed quality of service. Select H.323 from the drop-

down list box to configure this bandwidth filter for traffic that uses H.323. 
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 is N/A if you do not specify a 

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

subnetting.

Destination Port

Enter the port number of the destination. See 

 for some 

common services and port numbers. 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 is N/A if you do not specify a 

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

A blank source port means any source port number.
