Prioritize Streaming Audio/Video:

Belong to the QoS in L4. Just tick the option button and press <Apply> button to have this function taken affect. Then, click <Advance >>> button set up Special TCP/UDP port for QoS.

Prioritize Databases (Oracle, IBM DB2, SQL, Microsoft):

Belong to the QoS in L4. Just tick the option button and press <Apply> button to have this function taken affect. Then, click <Advance >>> button to set up Special TCP/UDP port for QoS.

Advanced Mode:

Display the TCP/UDP port number in L4 QoS. In “Disable IP TCP/UDP Port Classification” mode, user can randomly choose TCP/UDP port number that L4 QoS will affect. As to other special L4 QoS events, Special TCP/UDP port number will be took action. Of course, user could be allowed to add or modify the port number at random. For instance, if we choose “Down prioritize web browsing, e-mail, FTP and news” as the QoS of L4 and enter the “Advanced Mode”, then we can see that some special port number 80, 280, 443, 25, 110, 20, 21, 69, 119, 2009 have been configured already. User also has the right to modify these port numbers. The display is shown as Fig. 3-21.

Special TCP/UDP class:

There are two modes for selection, including Low and High. Default class (all other TCP/UDP ports):

There are two modes for selection, including Low and High. Port:

User can set up the port (1~24) respectively to let Special TDP/UDP class function work on them. If you would like to set up all ports at a time, user is allowed to choose “All” selection to simplify the procedure of configuration.

Special UDP/TCP Port Selection:

The following are port numbers defined by six specific networks in L4:

Down prioritize web browsing, e-mail, FTP and news: port number 80,280,443,25,110,20,21,69,119,2009

Prioritize IP Telephony (VoIP):1718,1719,1720

Prioritize iSCSI:3225,3260,3420

Prioritize web browsing, e-mail, FTP transfers and news: 80,280,443,25,110,20,21,69,119,2009

Prioritize Streaming Audio/Video: 2979,1755,7070,7071,554,8000

Prioritize Databases (Oracle, IBM DB2, SQL, Microsoft): 66,1571,1575,523,118,156,3306,1232,1433,1434
