MDI-X
Medium Dependent Interface Crossover
An Ethernet port connection that allows networked end stations
(i.e., PCs or workstations) to connect to each other using a null-
modem, or crossover, cable. For 10/100 full-duplex networks, an
end point (such as a computer) and a switch are wired so that
each transmitter connects to the far end receiver. When
connecting two computers together, a cable that crosses the TX
and RX is required to do this. With auto MDI-X, the PHY senses
the correct TX and RX roles, eliminating any cable confusion.
MIB
Management Information Base
The MIB comprises the management portion of network devices.
This can include things like monitoring traffic levels and faults
(statistical), and can also change operating parameters in network
nodes (static forwarding addresses).
MII
Media Independent Interface
The MII accesses PHY registers as defined in the IEEE 802.3
specification.
NIC
Network Interface Card
An expansion board inserted into a computer to allow it to be
connected to a network. Most NICs are designed for a particular
type of network, protocol, and media, although some can serve
multiple networks.
NPVID
Non Port VLAN ID
The Port VLAN ID value is used as a VLAN reference.
PLL
Phase-Locked Loop
An electronic circuit that controls an oscillator so that it maintains a
constant phase angle (i.e., lock) on the frequency of an input, or
reference, signal. A PLL ensures that a communication signal is
locked on a specific frequency and can also be used to generate,
modulate, and demodulate a signal and divide a frequency.
PME
Power Management Event
An occurrence that affects the directing of power to different
components of a system.
QMU
Queue Management Unit
Manages packet traffic between MAC/PHY interface and the
system host. The QMU has built-in packet memories for receive
and transmit functions called TXQ (Transmit Queue) and RXQ
(Receive Queue).
SA
Source Address
The address from which information has been sent.
TDR
Time Domain Reflectometry
TDR is used to pinpoint flaws and problems in underground and
aerial wire, cabling, and fiber optics. They send a signal down the
conductor and measure the time it takes for the signal -- or part of
the signal -- to return.
UTP
Unshielded Twisted Pair
Commonly a cable containing 4 twisted pairs of wires. The wires
are twisted in such a manner as to cancel electrical interference
generated in each wire, therefore shielding is not required.
VLAN
Virtual Local Area Network
A configuration of computers that acts as if all computers are
connected by the same physical network but which may be
located virtually anywhere.
