B&B Electronics EIR608-xSFP manual Igmp Configuration, TOS Configuration

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.

Message	Description
	A message sent from the querier (IGMP router or switch)
Query	asking for a response from each host belonging to the
	multicast group.

Report	host wants to be or is a member of a given group indicated in
	the report message.
