Glossary
1000BASE-T
–1000BASE-T - Known as IEEE 802.3ab which is a standard for
Gigabit Ethernet over copper wiring.
100BASE-TX
– 100Mbps Ethernet implementation over Category 5 and Type 1
Twisted Pair cabling.
10BASE-T
– The IEEE 802.3 specification for Ethernet over Unshielded
Twisted Pair (UTP) cabling.
aging
– The automatic removal of dynamic entries from the Switch Database
which have timed-out and are no longer valid.
ATM
–
Asynchronous Transfer Mode. A connection oriented transmission
protocol based on fixed length cells (packets). ATM is designed to carry a
complete range of user traffic, including voice, data, and video signals.
Auto-Negotiation
– A feature on a port, which allows it to advertise its
capabilities for speed, duplex, and flow control. When connected to an end
station that also supports auto-negotiation, the link can self-detect its optimum
operating setup.
Backbone port
–
A port that does not learn device addresses, and that
receives all frames with an unknown address. Backbone ports are normally
used to connect the Switch to the backbone of your network. Note that
backbone ports were formerly known as designated downlink ports.
Backbone
–
The part of a network used as the primary path for transporting
traffic between network segments.
Bandwidth
– Information capacity, measured in bits per second, that a channel
can transmit. The bandwidth of Ethernet is 10Mbps. the bandwidth of Fast
Ethernet is 100Mbps.
Baud rate
– The switching speed of a line. Also known as
line speed
.
BOOTP
– The BOOTP protocol allows you to automatically map an IP address
to a given MAC address each time a device is started. In addition, the protocol
can assign the subnet mask and default gateway to a device.
Bridge
– A device that interconnects local or remote networks no matter what
higher level protocols are involved. Bridges form a single logical network,
centralizing network administration.
Broadcast
– A message sent to all destination devices on the network.
Broadcast Storm
– Multiple simultaneous broadcasts that typically absorb
available network bandwidth and can cause network failure.
Console port
– The port on the Switch accepting a terminal or modem
connector. It changes the parallel arrangement of data within computers to the
serial form used on data transmission links. This port is most often used for
dedicated local management.
