Class of Service Additional Ranges Window
2 Enter the beginning of the port or socket range for
the application in the Range Start box.
The range start should be a hexadecimal value with a
maximum of four digits.
3 Enter the inclusive range end value of the port or
socket range for the application.
The range end should be a hexadecimal number with a
maximum of four digits. If only one port or socket is
needed, Range End should match Range Start.
4 Select the protocol that the application uses.
The protocol can be TCP, UDP, or IPX.
Some applications support multiple protocols and have
port or socket ranges for each protocol. In this case, the
range or protocol must match the protocol on the PC. For
example, if only TCP/IP is installed, do not enter the socket
range for IPX, because doing so will adversely affect driver
performance.
