Chapter 15 Bandwidth Management

P-660HWP-Dx User’s Guide

The following table describes the labels in this screen.  

Table 94   Bandwidth Management Rule Configuration

Rule Configuration

Active

Select this check box to have the P-660HWP-Dx 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.

Enable DiffServ 

Marking

Select this option to enable DiffServ marking on the P-660HWP-Dx.

DiffServ mark

Select the marking rule from the drop-down list. The first three digits are the 

DiffServ code point. A packet with the lowest priority mark will be dropped when 

the line is busy. 

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.
