DESCRIPTION

 

 

 

 

 

 

Borrow bandwidth

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

 

 

from parent class

if the parent class is not using up its bandwidth budget.

 

 

 

Bandwidth borrowing is governed by the priority of the child-classes. That is, a

 

 

 

child-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 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 Summary screen).

 

 

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

You can select a predefined service instead of configuring the Destination Port,

 

 

 

Source Port and Protocol ID fields.

 

 

 

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.

 

 

 

When you select None, the bandwidth class applies to all services unless you

 

 

 

specify one by configuring the Destination Port, Source Port and Protocol ID

 

 

 

fields.

 

 

Destination IP

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

 

 

Address

IP address means any destination IP address.

 

 

Destination Subnet

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

 

 

Mask

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

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

 

 

Mask

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.
