• Full Duplex Mode — Permits for bisynchronous communication, for example, a telephone. Two parties
can transmit information at the same time.
• Half Duplex Mode — Permits asynchronous communication, for example, a walkie-talkie. Only one party
can transmit information at a time.
E
Egress Ports
Ports from which network traffic is transmitted.
End System
An end user device on a network.
Ethernet
Ethernet is standardized as per IEEE 802.3. Ethernet is the most common implemented LAN standard.
Supports data transfer rates of Mpbs, where 10, 100 or 1000 Mbps is supported.
EWS
Embedded Web Server. Provides device management via a standard web browser. Embedded Web Servers are used
in addition to or in place of a CLI or NMS.
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 devices, 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.
