The role of an Ethernet switch is to forward Ethernet frames from one port to another. The presence of a FIB is one attribute that separates a switch from a hub. Without a functional FIB, all frames received by a network switch would be echoed back out to all other ports, much like an Ethernet hub.
For inserting a protocol analyzer into a network connection, a hub is an alternative to a network tap or port mirroring. [12] A hub with both 10BASE-T ports and a 10BASE2 port can be used to connect a 10BASE2 segment to a modern Ethernet-over-twisted-pair network. A hub with both 10BASE-T ports and an AUI port can be used to connect a 10BASE5 ...
Avaya ERS 2550T-PWR, a 50-port Ethernet 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.
The bridge has three ports. A is connected to bridge port 1, B is connected to bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge. The bridge examines the source address of the frame and creates an address and port number entry for host A in its forwarding table. The bridge examines the destination ...
RSTP adds new bridge port roles in order to speed convergence following a link failure: Root – A forwarding port that is the best port from non-root bridge to root bridge; Designated – A forwarding port for every network segment; Alternate – An alternate path to the root bridge. This path is different from using the root port

Bridging solutions for Token Ring and Ethernet networks included the AT&T StarWAN 10:4 Bridge, [25] the IBM 8209 LAN Bridge [25] and the Microcom LAN Bridge. Alternative connection solutions incorporated a router that could be configured to dynamically filter traffic, protocols and interfaces, such as the IBM 2210-24M Multiprotocol Router ...
