Gigabit Ethernet Switch User's Guide MIBs The information stored in the Switch is known as the Management Information Base (MIB). The Switch uses the standard MIB-II Management Information Base module. Consequently, MIB values inside the Switch can be retrieved from any SNMP-based network manager. - D-Link DGS-3204 | User Guide - Page 36
Gigabit Ethernet Switch User's Guide Packet Forwarding The Switch looks at the network configuration to forward packets. This reduces the traffic congestion on the network, because packets, instead of being transmitted to all segments, are transmitted to the destination only. Example: if Port 1 - D-Link DGS-3204 | User Guide - Page 37
Switch determines that a problem has developed in the primary paths. When a primary path is lost, the switch providing the alternative path will automatically go into service with no operator intervention. This automatic network reconfiguration provides maximum uptime to network users. The concept - D-Link DGS-3204 | User Guide - Page 38
Gigabit Ethernet Switch User's Guide there is more than one path, forwarded packets will automatically activated, and STA will automatically re-configure the network topology.

In this example, you can anticipate some major network problems if the STA assistance is not applied - D-Link DGS-3204 | User Guide - Page 42
Gigabit Ethernet Switch User's Guide STA setup can be somewhat complex. Therefore, you are advised to keep the default factory settings and STA will automatically assign root bridges/ports and block loop connections.
