F FFT Fast Forward Table. Provides information about forwarding routes. If a packet arrives to a device with a known route, the packet is forwarded via a route listed in the FFT. If there is not a known route, the CPU forwards the packet and updates the FFT. FIFO First In First Out. A queuing process where the first packet in the queue is the first packet out of the packet. Flapping Flapping occurs when an interfaces state is constantly changing. For example, an STP port constantly changes from listening to learning to forwarding. This may cause traffic loss. Flow Control Enables lower speed devices to communicate with higher speed device s, that is, that the higher speed device refrains from sending packets. Fragment Ethernet packets smaller than 576 bits. Frame Packets containing the header and trailer information required by the physical medium. G GARP General Attributes Registration Protocol. Registers client stations into a Multicast domain. Gigabit Ethernet Gigabit Ethernet transmits at 1000 Mbps, and is compatible with existing 10/100 Mbps Ethernet standards. GVRP GARP VLAN Registration Protocol. Registers client stations into a VLANs. H HOL Head of Line. Packets are queued. Packets at the head of the queue are forwarded before packets at the end of the line. Host A computer that acts as a source of information or services to other computers. HTTP HyperText Transport Protocol. Transmits HTML documents between servers and clients on the internet. Glossary 391
