Enable DiffServ

Marking

Select this option to enable DiffServ marking on the Prestige.

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.

Bandwidth Filter
The Prestige uses a bandwidth filter to identify the traffic that belongs to a bandwidth class.

Active

Select the check box to have the Prestige use this bandwidth filter when it

performs bandwidth management.

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 None from the drop-down list box if you do not want to use a predefined

application for the bandwidth class. When you select None, 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 IP

Address

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

IP address means any destination IP address.

Destination Subnet

Mask

Enter the destination subnet mask. This field is N/A if you do not specify a

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

subnetting.

Destination Port

Enter the port number of the destination. A blank destination port means any

destination port.

Source IP Address

Enter the source IP address. A blank source IP address means any source IP

address.

Source Subnet

Mask

Enter the source subnet mask. This field is N/A if you do not specify a Source IP

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

Source Port

Enter the port number of the source. See the following table for some common

services and port numbers. A blank source port means any source port number.

Protocol ID

Enter the protocol ID (service type) number, for example: 1 for ICMP, 6 for TCP

or 17 for UDP. A blank protocol ID means any protocol number.

TOS (Type of

Service)

TOS defines the DS(Differentiated Service) field in the IP header. Enter the new

TOS value of the outgoing packet (between 0 and 255). 0 is the lowest priority.
