Glossary
Basic Encoding Rules. A language for describing transfer syntax.
BER. See Basic Encoding Rules.
broadcast trap destination. In a SNMP agent configuration, a trap destination to which the
SNMP agent directs traps when not specifically told to send a directed trap by the
subagent. See also trap destination and directed trap destination.
coldStart trap. A trap signaling that the SNMP agent has been initialized and that some
object values may change as a result. This trap is generated by the SNMP agent when
it is first started or when its backup process takes over. In addition, whenever a
TRAPDEST object is added and started, the SNMP agent sends a coldStart trap to it.
collector. A process, defined by EMS, to which subsystems report events.
columnar objects. The table cells that make up a table row.
community. The relationship between an SNMP agent and one or more SNMP managers
that defines access to MIB objects. An agent establishes one community for each
combination of access mode and SNMP manager station(s).
community name. A string of 1 to 50 characters identifying a community. SNMP messages
always contain a community name. If the community name corresponds to a
community known to the receiving SNMP entity, the receiving entity accepts the
message.
connection. A logical binding between two or more users of a service. Also, the path
between two protocol modules that provides reliable stream delivery service.
connectionless. Characterized by the absence of logical connections between
communicating entities. Connectionless operation requires that the data itself contain
all the context information, such as addresses, required to get it to its destination and
identify it to the recipient. Higher levels of protocol, or the application itself, are
responsible for message sequencing and error handling.
connection-oriented. Characterized by logical connections between communicating
entities. Connection-oriented protocols ensure that data arrives at its destination in
sequence and error free.
DARPA. See Defense Advanced Research Projects Agency.
datagram. The basic unit of information passed across the Internet. It is a self-contained
unit of data transmitted independently of other datagrams. It contains the source and
the destination address, along with the data to be transferred.
Defense Advanced Research Projects Agency. The agency of the U.S. Department of
Defense under which the Internet suite of protocols was developed.
