DESCRIPTION
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.
Enter the destination IP address in dotted decimal notation. A blank destination
IP address means any destination IP address.
Enter the destination subnet mask. This field is N/A if you do not specify a
Destination IP Address. Refer to the appendix for more information on IP
subnetting.
Enter the port number of the destination. A blank destination port means any
destination port.
Enter the source IP address. A blank source IP address means any source IP
address.
Enter the source subnet mask. This field is N/A if you do not specify a Source IP
Address. Refer to the appendix for more information on IP subnetting.
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.
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.
