TOS Configuration
„ TOS priority: the system provides 0 to 63 TOS priority levels. Each
level has four types of priority – high, middle, low, and lowest. The default
value is ‘Lowest’. When an IP packet is received, the system will check the
TOS level value in the IP packet. For example, if the TOS level 25 is high
and the port is following the TOS priority policy only, when a packet is
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), then the packet
will have highest priority.

IGMP Configuration
The Internet Group Management Protocol (IGMP) is an internal protocol of
the Internet Protocol (IP) suite. IP manages multicast traffic by using
switches, routers, and hosts that support IGMP. Enabling IGMP allows the
ports to detect IGMP queries and report packets and manage IP multicast
traffic through the switch. IGMP has three fundamental types of message.
