2. MAC-Forced Forwarding - Wikipedia

   en.wikipedia.org/wiki/MAC-Forced_Forwarding

   MACFF is described in RFC 4562, MAC-Forced Forwarding: A Method for Subscriber Separation on an Ethernet Access Network. Allied Telesis switches implement MACFF using DHCP snooping to maintain a database of the hosts that appear on each switch port. When a host tries to access the network through a switch port, DHCP snooping checks the host’s ...

3. Network switch - Wikipedia

   en.wikipedia.org/wiki/Network_switch

   A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data ...

4. Forwarding information base - Wikipedia

   en.wikipedia.org/wiki/Forwarding_information_base

   Forwarding information base. A forwarding information base ( FIB ), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ...

5. Spanning Tree Protocol - Wikipedia

   en.wikipedia.org/wiki/Spanning_Tree_Protocol

   t. e. The Spanning Tree Protocol ( STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link ...

6. Medium access control - Wikipedia

   en.wikipedia.org/wiki/Medium_access_control

   The most widespread multiple access method is the contention-based CSMA/CD used in Ethernet networks. This mechanism is only utilized within a network collision domain, for example an Ethernet bus network or a hub-based star topology network. An Ethernet network may be divided into several collision domains, interconnected by bridges and switches.

7. Autonegotiation - Wikipedia

   en.wikipedia.org/wiki/Autonegotiation

   The first version of the autonegotiation specification, in the 1995 IEEE 802.3u Fast Ethernet standard, was implemented differently by different manufacturers leading to interoperability issues. These problems led many network administrators to manually set the speed and duplex mode of each network interface.
