MAC address (Media Access Control Address)
MAC address (Media Access Control Address). A value in the Medium Access Control 
sublayer of the IEEE/ISO/ANSI LAN architecture, that uniquely identifies an individual 
station that implements a single point of physical attachment to a LAN.
management applications. In DSM, an application process that opens a management or 
subsystem process to control a subsystem. This process can issue SPI commands to 
subsystems and retrieve EMS event messages to assist in the management of a 
computer system or a network of systems. A management application is a requester to 
the subsystems to which it sends commands; the subsystems are servers to the 
management application.
management process. A process through which an application issues commands to a 
subsystem. A management process can be part of a subsystem, or it can be 
associated with more than one subsystem. In the latter case, the management process 
is logically part of each subsystem. Subsystem Control Point (SCP) is the management 
process for all subsystems controlled by Subsystem Control Facility (SCF). See also 
subsystem.
manager process. In DSM, an HP subsystem process with which the SCP management 
process communicates to control a particular data communications subsystem.
MFIOB. See multifunction I/O board (MFIOB).
MON. The monitor object in Parallel Library TCP/IP. See TCPMON.
multifunction I/O board (MFIOB). A ServerNet adapter that contains ServerNet 
addressable controllers (SACs) for SCSI and Ethernet; a service processor; ServerNet 
links to the processor, to the two ServerNet adapter slots, and to one of the ServerNet 
expansion board (SEB) slots; and provides connections to the serial maintenance bus 
(SMB), which connects components within an enclosure to the service processor.
Network File System (NFS). A protocol developed by SUN Microsystems that uses IP to 
allow a set of cooperating computers to access each other's file systems as if they 
were local. The key advantage of NFS over conventional file transfer protocols is that 
NFS hides the differences between local and remote files by placing them in the same 
name space. NFS is used primarily on UNIX systems, but has been implemented for 
many systems, including personal computers like an IBM PC and Apple Macintosh.
noncritical event. A DSM event not too crucial to system or network operations. Each 
subsystem determines which of its events are noncritical by setting the value of the 
emphasis token to FALSE. Compare critical event. 
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 HP data communications subsystems, the 
nonsensitive commands are all those that cannot change the state or configuration of 
objects (usually information commands). Compare sensitive command.
