MDI
Medium Dependent
Interface
An Ethernet port connection that allows network hubs or switches to
connect to other hubs or switches without a null-modem, or crossover,
cable. MDI provides the standard interface to a particular media (copper or
fiber) and is therefore 'media dependent.'
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.
