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
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 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.
