network element
network element. A resource that is monitored and controlled by network management
applications. A network element consists of the managed entity (devices such as
hosts, gateways, and terminal servers) and the managed entity’s agent. The managed
entity’s agent is responsible for performing the network management functions
requested by the network management stations.
network interface file. The file used by the Host Resources Subagent to maintain values
for MIB objects in the hrNetworkTable.
network management application. A software application consisting of a single program
or a collection of programs that monitors and controls network elements. Network
management applications generally display the state of the network graphically.
network management protocol. The protocol used to convey management information.
SNMP is a network management protocol used to communicate management
information between managers and agents.
network management variable. A MIB object.
Network Operation Console. The system responsible for managing one or more nodes on
an internet network.
nnm group. A group of scalar objects in the NonStop NET/MASTER Trap MIB that is used
as variable bindings in the traps created from NonStop NET/MASTER events.
NMMTRAP. An NCL procedure of the NonStop NET/MASTER Trap Subagent which
contains procedures for opening and closing sessions with the SNMP agent and for
forwarding traps to the SNMP agent. Unlike GENTRAP, NMMTRAP’s NCL code should
not be modified.
NOC. See Network Operation Console.
NonStop NET/MASTER MS. A network management environment that lets you monitor
and control local and remote NonStop systems interactively or programmatically (using
NCL procedures). It also lets you tailor your individual operations environment.
not-accessible. A MIB object attribute that excludes access by any community to object
values.
object. An entity in an SNMP environment.
object descriptor. A textual name for an object.
object group. A logical collection of MIB objects with similar characteristics.
object identifier. A sequence of integers, derived by traversing an object tree, that identifies
a particular MIB object.
