TOS Configuration
Use this screen to set the TOS priority level.
TOS priority
- the system provides 0~63 TOS priority levels. Each level has four
types of priority – high, mid, low, and lowest. The default value is the
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 been received. For example: TOS level is set to 25.
Port 1 will follow the TOS priority policy only. When the packet for port 1 is received,
the system will check the TOS value of the received IP packet. If the TOS value of the
received IP packet is 25 (priority = high), the packet priority will have highest priority.

multicast traffic through the switch. IGMP provides the following three fundamental
types of messages:
