TOS Configuration
Set up the TOS priority.
 TOS priority: the system provides 0~63 TOS priority level. Each level has 4 types of
priority – high, mid, 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: user set the TOS level 25 is high. The port 1 is
following the TOS priority policy only. When the port 1 packet received, 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.
 Save the configuration.
