LMIB (Local Management Information Base).
LMIB (Local Management Information Base). See MIB (Management Information
Base)..
Local address. The terms local address and remote address refer to the two endpoints of a
connection. A local address is the address of the end-system which is considered local
with respect to the user.
Loopback connection. For qualifying applications, an improvement in throughput and
performance can be accomplished by using a loopback connection. Data is passed
between the applications only going as far as the TAPS processes, bypassing the TSP
and NSP processes. To use loopback, both applications must use #APPL entries, use the
same OSI manager process, and reside on the same OSI subsystem, with the called
application specifying loopback.
Major activity token. One of the four types of Session Layer tokens that are associated
with functional units.
Major synchronization. In the Session Layer, the separation of the exchange of data into a
series of dialog units. A major synchronization point indicates the end of one dialog
unit and the beginning of the next. Each major synchronization point is confirmed
explicitly.
MIB (Management Information Base). A database used by the OSI manager process to
store and retrieve configuration information and information about applications. The
MIB consists of the LDIB and the LMIB. The LDIB (Local Directory Information
Base) is the part of the MIB that contains local subsystem addressing information about
applications. The LMIB (Local Management Information Base) is the part of the MIB
that contains local subsystem configuration and management information.
Minor synchronization. In the Session Layer, the structuring of the exchange of data within
a dialog unit. Each minor synchronization point may or may not be confirmed
explicitly.
MLAM (Multilan access method). The I/O process that is part of the Compaq TLAM
product.
Network Layer. Layer 3 in the OSI Reference Model. This layer routes data by
establishing, maintaining, and terminating communications between nodes. It sets up
the most economical path, both physical and logical, between communicating nodes;
routes messages through intervening nodes to their destinations; and controls the flow of
messages between nodes.
Network service access point. See NSAP (network service access point).

Nonsensitive command. A DSM command that can be issued by any user or program
allowed access to the target subsystem—that is, a command on which the subsystem
imposes no further security restrictions. For Compaq data communications subsystems,
the nonsensitive commands are all those that cannot change the state or configuration of
objects (usually information commands).
