Table 103 Bandwidth Management Rule Configuration

LABEL	DESCRIPTION
Rule Configuration
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	Select this option to allow a rule to borrow unused bandwidth on the interface.
Bandwidth	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	Enter the destination subnet mask. This field is N/A if you do not specify a
Netmask	Destination Address. Refer to the appendix for more information on IP
	subnetting.
Destination Port	Enter the port number of the destination. See Appendix 31 on page 371 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.
