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 appendices for more information on IP
subnetting.
Destination Port Enter the port number of the destination. See Table 74 on page 189 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 appendices for more information on IP subnetting.
A blank source port means any source port number.
Source Port Enter the port number of the source. See Table 74 on page 189 for some
common services and port numbers.
Protocol Select the protocol (TCP or UDP) or select User defined and enter the protocol
(service type) number. 0 means any protocol number.
