User’s Manual of FGSW-2840 / FGSW-4840S 4.6 Multicast Multicast Overview In the network, packets are sent in three modes: unicast, broadcast and multicast. In unicast, the source server sends separate copy information to each receiver. When a large number of users require this information, the server must send many pieces of information with the same content to the users.

User’s Manual of FGSW-2840 / FGSW-4840S 7. SWITCH OPERATION 7.1 Address Table The Managed Switch is implemented with an address table. This address table is composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port no, etc. This information comes from the learning process of Ethernet Switch.
Page 257: Auto-Negotiation
User’s Manual of FGSW-2840 / FGSW-4840S The Managed Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the re-transmission rate. No packet loss will occur. 7.5 Auto-Negotiation The STP ports on the Managed Switch have built-in "Auto-negotiation". This technology automatically sets the best possible bandwidth when a connection is established with another network device (usually at Power On or Reset).
