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.
