Active Select the check box to have the Prestige use this bandwidth filter when it
performs bandwidth management.
Service 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.

specify one by configuring the Destination Port, Source Port and Protocol ID
fields.
