Table 83 Bandwidth Manager: Edit Class (continued)

LABEL

DESCRIPTION

 

 

Borrow bandwidth

Select this option to allow a sub-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 sub-classes. That is, a

 

sub-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 (see Section 19.8.1 on page

 

201) 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 Table 81 on page 204).

Filter Configuration

 

 

 

Enable Bandwidth

Select Enable Bandwidth Filter to have the Prestige use this bandwidth filter

Filter

when it performs bandwidth management.

 

You must enter a value in at least one of the following fields (other than the

 

Subnet Mask fields which are only available when you enter the destination or

 

source IP address).

Application

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).

 

FTP (File Transfer Program) is a program to enable fast transfer of files,

 

including large files that may not be possible by e-mail. Select FTP from the

 

drop-down list box to configure the bandwidth filter for FTP traffic.

 

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

 

telephony, instant messaging, events notification and conferencing. The

 

Prestige supports SIP traffic pass-through. Select SIP from the drop-down list

 

box to configure this bandwidth filter for SIP traffic. This option makes it easier

 

to manage bandwidth for SIP traffic and is useful for example when there is a

 

VoIP (Voice over Internet Protocol) device on your LAN.

 

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

Enter the destination IP address in dotted decimal notation.

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 Appendix D on page 356 for more

 

information on IP subnetting.

Destination Port

Enter the port number of the destination. See Table 84 on page 208 for a table

 

of services and port numbers.

Source IP Address

Enter the 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 Appendix D on page 356 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.

Protocol ID

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

 

or 17 for UDP.
