hrSWRunPerf group
hrSWRunPerf group.
The optional MIB-II group in the Host Resources Subagent’s MIB
that describes the resource consumption of the processes contained in the hrSWRun
group.
hrSystem group.
The MIB-II group in the Host Resources Subagent’s MIB that describes
general host characteristics, such as the number of current users.
ICMP.
See
Internet Control Message Protocol.
ICMP group.
The group in MIB-II supported by the TCP/IP Subagent that provides
information about the ICMP layer of a TCP/IP subsystem being managed.
IFTBL.
See
network interface file.
instance.
A single occurrence of a MIB object. Some MIB objects have only a single
instance: for example, sysDescr. Other MIB objects have several instances: for
example, ifType.
interface layer.
The layer in the Internet suite of protocols responsible for transmission at
the hardware (media) level.
Interfaces group.
The MIB-II group that provides information about the network interfaces
of a TCP/IP subsystem being managed.
internet.
When spelled with a lowercase “i,” internet refers to any collection of packet-
switching networks that use the TCP/IP protocol suite. The Internet, spelled with an
uppercase “I,” is the largest internet in existence.
Internet.
A large collection of connected networks that use the Internet suite of protocols
and function as a single, cooperative, virtual network. The Internet provides universal
connectivity and three levels of network service: unreliable, connectionless packet
delivery; reliable, full-duplex stream delivery; and application-level services (like
electronic mail) that build on the first two. The Internet reaches many universities,
government research labs, commercial organizations, and military installations.
Internet Activities Board.
The technical body overseeing the development of the Internet
suite of protocols.
Internet address.
The 32-bit address assigned to hosts that want to participate in the
Internet using TCP/IP. Internet addresses are an abstraction of physical hardware
addresses, just as the Internet is an abstraction of physical networks. Actually
assigned to the interconnection of a host to a physical network, an Internet address
consists of a network portion and a host portion.
Internet Control Message Protocol.
A simple reporting protocol for the Internet Protocol
(IP) that provides low-level feedback about how the internet layer is operating. It
supports a modest number of basic control messages for error reporting. Specifically,
gateways and hosts use ICMP to send reports of problems about datagrams back to
the original source of the datagram. ICMP also includes an echo request-reply used to
