Glossary

Fault isolation

A technique for identifying and alerting administrators about connections (such as those associated with
switch ports) that are experiencing congestion or failure, or exceeding an administrator-defined threshold.

Fast STP

A high-performance Spanning Tree Protocol. See “STP” on page 22 for more information.

Filtering

The process of screening a packet for certain characteristics, such as source address, destination address, or
protocol. Filtering is used to determine whether traffic is to be forwarded, and can also prevent unauthorized
access to a network or network devices.

Flash Memory

See “EEPROM” on page 8.

Flow Control

The process of adjusting the flow of data from one network device to another to ensure that the receiving
device can handle all of the incoming data. This is particularly important where the sending device is
capable of sending data much faster than the receiving device can receive it. There are many flow control
mechanisms. One of the most common flow control protocols for asynchronous communication is called
xon-xoff. In this case, the receiving device sends a an “xoff” message to the sending device when its buffer
is full. The sending device then stops sending data. When the receiving device is ready to receive more data,
it sends an “xon” signal.

Forwarding

When a frame is received on an input port on a switch, the address is checked against the lookup table. If the
lookup table has recorded the destination address, the frame is automatically forwarded on an output port.

Full-duplex

A system that allows packets to be transmitted and received at the same time and, in effect, doubles the
potential throughput of a link.

G

GARP

See “Generic Attribute Registration Protocol.” on page 10.

GARP Information Propagation

GIP is the propagation of information between GARP participants for the same application in a bridge is
carried out by a GIP component.
