socket.
socket. A pairing of an IP address and a port number. Also, a logical connection between
two applications across a TCP/IP network. On SNMP systems, a socket corresponds
to a file system open. The same application or system can use multiple sockets. When
you identify the process or device with which you want to communicate, you identify
the socket by specifying the address and port.
SPI. See Subsystem Programmatic Interface.
startup parameter. A parameter you specify when you invoke the SNMP agent or a
subagent to control attributes of the running agent or subagent processes.
subagent. A process that handles a particular collection of network resources on behalf of
an SNMP agent. Examples of subagents offered on SNMP systems are the EMS Trap
Subagent and the Host Resources Subagent.
Subagent Toolkit. The product offered by HP that helps programmers generate subagents
that make SNMP resources manageable by SNMP managers.
subnet. A physical network within an IP network. The terms “subnet” and “subnetwork” are
used interchangeably.
Subsystem Control Facility. The interactive product you use to configure, control, and
collect information about many SNMP subsystems. SCF is the primary configuration
management facility for the SNMP agent.
Subsystem Control Point. A process through which management applications, including
SCF, control subsystems.
Subsystem Programmatic Interface. A set of procedures and associated definition files
and a standard message protocol used to define common message-based interfaces
for communication among applications and subsystems that run on NonStop systems.
subtree. On an object tree, a node that is not the root or a leaf. It acts as the logical root of
a related set of objects descending from it.
syh group. A collection of scalar objects in the Syshealth Trap MIB that is used as variable
bindings in traps created from Syshealth events.
System group. The MIB-II group supported by the SNMP agent that provides information
about the agent and the node on which it resides.
table. See MIB table.
Tandem LAN Access Method (TLAM). The pre-G-series communication subsystem that
provides a LAN interface to the NonSTop system. TLAM software implements the IEEE
802.2 Logical Link Control (LLC) local area network (LAN) standard, providing a
uniform interface between upper-layer protocol products (such as TCP/IP) and the
physical LAN medium. In addition to 802.2 type 1 connectionless service, TLAM
supports Ethernet and IEEE 802.3 protocols. TLAM allows NonStop systems to
