Cisco Express Forwarding --An advanced Layer 3 IP switching technology. Cisco Express Forwarding optimizes network performance and scalability for networks with large and dynamic traffic patterns.
index --A method of uniquely identifying a tunnel.
instance --An occurrence. An object can have one or more instances.
IS-IS --Intermediate System-to-Intermediate System. IS-IS is an OSI link-state hierarchical routing protocol based on DECnet Phase V routing where intermediate system (IS) routers exchange routing information based on a single metric to determine network topology.
label --A short, fixed-length data construct that tells switching nodes how to forward data (packets or cells).
LFIB --Label Forwarding Information Base. The data structure for storing information about incoming and outgoing tags (labels) and associated equivalent packets suitable for labeling.
LSR --label switching router. A device that forwards MPLS packets based on the value of a fixed-length label encapsulated in each packet.
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 using 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.
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 event within Cisco software has occurred.
object --A variable that has a specific instance associated with it.
OSPF --Open Shortest Path First. Link-state, hierarchical Interior Gateway Protocol (IGP) routing algorithm proposed as a successor to Routing Information Protocol (RIP) in the Internet community. OSPF features include least-cost routing, multipath routing, and load balancing.
RSVP --Resource Reservation Protocol. Protocol for reserving network resources to provide quality of service (QoS) guarantees to application flows.
scalar object--Objects that are not instances. A scalar object has one instance.
SNMP --Simple Network Management Protocol. A network management protocol used almost exclusively in TCP/IP networks. SNMP provides a means to monitor and control network devices, manage configurations, collect statistics, monitor performance, and ensure network security.
SNMP agent--A managed node or device. The router that has the MIB implementation on it.
