inform
--A type of notification message that is more reliable than a conventional trap notification message because the informs message
notification requires acknowledgment, but a trap notification does not.
IPC
--Inter-Process Communication. The protocol used by routers that support distributed packet forwarding. The Cisco IOS XE version
of IPC provides a reliable ordered delivery of messages using an underlying platform driver transport or User Date Protocol
(UDP) transport protocol. Cisco IOS XE software IPC services allow line cards (LCs) and the central route processor (RP) in
a distributed system, to communicate with each other by exchanging messages from the RP to the LCs. Communication messages
are also exchanged between active and standby RPs. The IPC messages include configuration commands, responses to the configuration
commands, and other events that are reported by an LC to the RP.
MIB
--Management Information Base. A database of network management information that is used and maintained by a network management
protocol such as Simple Network Management Protocol (SNMP). The value of a MIB object can be changed or retrieved by the use
of SNMP commands, usually through a network management system. MIB objects are organized in a tree structure that includes
public (standard) and private (proprietary) branches.
NMS
--network management station. A powerful, well-equipped computer (typically an engineering workstation) that is used by a
network administrator to communicate with other devices in the network. An NMS is typically used to manage network resources,
gather statistics, and perform a variety of network administration and configuration tasks. In the context of SNMP, an NMS
is a device that performs SNMP queries to the SNMP agent of a managed device to retrieve or modify information.
notification
--A message sent by a Simple Network Management Protocol (SNMP) agent to a network management station, console, or terminal
to indicate that a significant network event has occurred.
SNMP
--Simple Network Management Protocol. A network management protocol used almost exclusively in TCP/IP networks. SNMP enables
a user to monitor and control network devices, manage configurations, collect statistics, monitor performance, and ensure
network security.
SNMP
community
--An authentication scheme that enables an intelligent network device to validate SNMP requests.
SNMPv2c
--Version 2c of the Simple Network Management Protocol. SNMPv2c supports centralized as well as distributed network management
strategies and includes improvements in the Structure of Management Information (SMI), protocol operations, management architecture,
and security.
SNMPv3
--Version 3 of the Simple Network Management Protocol. Interoperable standards-based protocol for network management. SNMPv3
provides secure access to devices by a combination of authenticating and encrypting packets over the network.
trap
--A message sent by an SNMP agent to a network management station, console, or terminal to indicate that a significant network
event has occurred. Traps are less reliable than inform requests, because the receiver of the trap does not send an acknowledgment
of receipt; furthermore, the sender of the trap cannot determine if the trap was received.
