Glossary MDIX MDU MIB MTU Multicast Network Processor NMS Node OID OSPF Packet PDU PING Policing Media Dependent Interface with Crossover (MDIX). A cable used for hubs and switches. Multiply-Divide Unit. A high-speed circuit that performs multiplication and division within the CPU. Management Information Base. MIBs contain information describing specific aspects of network components. Maximum Transfer Unit. Specifies the maximum frame size that can be transmitted over a network. Frames that exceed the MTU must be broken into smaller frames. Transmits copies of a single packet to multiple ports. N CPU chips that are optimized for networking and communications functions. Network Management System. An interface that provides a method of managing a system. A network connection endpoint or a common junction for multiple network lines. Nodes include: • Processors. • Controllers. • Workstations. O Object Identifier. Used by SNMP to identify managed objects. In the SNMP Manager/Agent network management paradigm, each managed object must have an OID to identify it. Open Shortest Path First. A TCP/IP Interior Gateway protocol that calculates the lowest-cost route, multipath routing, and load balancing. P Blocks of information for transmission in packet switched systems. Protocol Data Unit. A data unit specified in a layer protocol consisting of protocol control information and layer user data. Packet Internet Groper. Verifies if a specific IP address is available. A packet is sent to another IP address and waits for a reply. Determines if traffic levels are within a specified profile. Policing manages the maximum traffic rate used to send or receive packets on an interface. Embedded Web System User Guide www.hp.com Glossary-9
