of priority—High, Middle, Low, and Lowest. The default value is ‘Lowest’ priority for
each level. When the IP packet is received, the system will check the TOS level value in
the IP packet that has received. For example, the user sets the TOS level 25 as high,
the system will check the TOS value of the received IP packet. If the TOS value of
received IP packet is 25 (priority = high), and then the packet priority will have highest
priority.
