been adopted by ANSI. The 802.5 committee
produced the standard for a Token Ring local
area network which has been adopted by
ANSI.
IEEE 802.3 network: A
10-megabit-per-second LAN, described by
the ANSI/IEEE 802.3 Standard for Local
Area Networks, which uses a CSMA/CD
network access method.
IEEE 802.5 network: A 16- or
4-megabit-per-second LAN 802.5 network
which has a token passing network access
method and a ring or star configuration.
Internet Address: The network address of
a computer node. This address identifies
both which network the host is on and which
host it is. Refer to the Installing and
Administering LAN/9000 Software manual
for detailed information about network
addressing.
IP Address: See Internet Address.
LAN: See Local Area Network.
LED: Light Emitting Diode, a
semiconductor chip that emits light when
activated. LEDs are commonly used as
visible indicators to inform users that
various components in a computer system or
other electronic device are functioning.
Lobe Cable: Used interchangeably with
adapter cable; lobe cables attach at one end
to a token ring adapter in the system and at
the other end to a wall jack or TAU.
Local Area Network (LAN): A data
communications system that allows a
number of independent devices to
communicate with each other.
Local Network: The network to which a
node is directly attached.
Major Number: Unique value that
identifies an individual hardware device.
MIB: Management Information Base. A
virtual data base of managed objects
contained within the SNMP agent. The MIB
is not a physically distinct database, but
rather it is a concept that includes
configuration and status values normally
available on the agent system. MIB I
includes objects dealing with IP
internetworking routing variables. MIB II or
link-specific MIB extensions, now an
Internet standard, add new objects to the
MIB I groups and also adds two new groups.
The new groups add media devices and
network devices to the SNMP capabilities.
Maximum Transmission Unit (MTU).
Largest amount of data that can be
transmitted through that interface. This
value does not include the LLC or MAC
headers.
Network Architecture: Any point in a
network where services are provided or
communications channels are
interconnected. A node could be a
workstation or a server processor.
Network Interface: Acommunication path
through which messages can be sent and
received. A hardware network interface has
a hardware deviceassociated with it, such as
a LAN or FDDI card. A software network
interface does not includea hardware device,
for example the loopback interface. For every
IP address instance, there must be one
network interface configured.
