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. 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. 434 Glossary

Glossary
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.
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.
