media access control (MAC) address
media access control (MAC) address. A MAC address is 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. In DSM, an HP 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 of the subsystems. SCP is the management process
for all HP data communications subsystems that support DSM. 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).
MILNET (Military Network). Originally part of the ARPANET, MILNET was partitioned in
1984 to make it possible for military installations to have reliable network service, while
the ARPANET continues to be used for research. MILNET uses exactly the same
hardware and protocol technology as ARPANET, and there are several interconnection
points between the two. Therefore, under normal circumstances, MILNET sites are part
of the Internet.
multicast. A technique that allows copies of a single packet to be passed to a selected
subset of all possible destinations. Some hardware (for example, Ethernet) supports
multicast by allowing a network interface to belong to one or more multicast groups.
Broadcast is a special form of multicast in which the subset of machines selected to
receive a copy of a packet consists of the entire set.
multicast address. An identifier for a set of interfaces (typically belonging to different
nodes). A packet sent to a multicast address is delivered to all interfaces identified by
that address.
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.
neighbor. A node that is attached to the same link.
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
