Signamax 065-7931 16-Port 10/100/1000BaseT/TX WebSmart Switch
71
Function name:
IP TCP/UDP Port Classification
Function description:
In L4 QoS Configuration, you can enter a special network transmission event
to prioritize it appropriately; for example we use ”Down prioritize web browsing,
e-mail, FTP and news“ in the L4 QoS Configuration and click apply, and then
click Custom L4. We can find Special TCP/UDP port 80, 280, 443, 25, 110, 20,
21, 69, 119, 2009 have already existed and are defined for your use, but it is
possible for you to modify this pre-defined TCP/UDP port with other port
numbers you prefer. In ”Down prioritize web browsing, e-mail, FTP and news“,
L4 QoS Configuration with a default setting, specially defined TCP/UDP port
possesses a lower QoS traffic than Default class (all other TCP/UDP ports
such as port 81,82,83,84,85,etc.). As an example, when we transmit TCP
packets with port number 80 from port 2 and port number 81 from port 3 to
port 1 until congestion occurs, the packets from port 3 will be dropped by port
1 because the TCP packets have port number 80 assigned as high priority and
will have a higher precedence to be forwarded from port 1.
