Data center switching - The point of aggregation within a corporate network where a swit ch provides high-performance access t o server farms, a high-speed backbone connect ion, and a control point for network management and security. Ethe rnet - A LAN specification developed jointly by Xerox, Intel, and Digital Equipment Corporat ion. Et hernet net works operat e at 10Mbps using CSMA/CD to run over cabling. Fast Etherne t - 100Mbps technology based on the Ethernet/CD network access method. Flow Control - (IEEE 802.3z) A means of holding packets back at the transmit port of the connected end station. Prevents packet loss at a congested switch port. Forwardin g - The process of sending a packet t oward it s dest inat ion by an internet working device. Full -du plex - A syst em t hat allows packet s to be transmitt ed and received at the same t ime and, in effect , doubles the potent ial throughput of a link. Half-duplex - A system that allows packets to be transmitted and received, but not at the same time. Contrast with full-duplex. IP address - Internet Protocol address. A unique identifier for a device attached to a network using T CP/IP. The address is written as four octets separated with full-stops (periods), and is made up of a network section, an optional subnet section and a host section. IPX - Internetwork Packet Exchange. A protocol allowing communication in a NetWare n et wo rk . LAN - Local Area Network. A network of connected computing resources (such as PCs, printers, servers) covering a relatively small geographic area (usually not larger than a floor or building). Characterized by high data rates and low error rates. Latency - The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port. Line speed - See baud rate. main port - The port in a resilient link that carries data traffic in normal operating con dit ion s. MDI - Medium Dependent Interface. An Ethernet port connection where the transmitter of one device is connected to the receiver of another device. MDI-X - Medium Dependent Interface Cross-over. An Ethernet port connection where the internaltransmit and receive lines are crossed. MIB - Management Information Base. Stores a device's management characteristics and parameters. MIBs are used by the Simple Network Management Protocol (SNMP) to contain attributes of their managed systems. The Switch contains its own internal MIB. Multicast - Single packets copied to a specific subset of network addresses. These addresses are specified in the destination-address field of the packet. Protocol - A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing, and error control. Re silient link - A pair of ports that can be configured so that one will take over data transmission should the other fail. See also main port and standby port. RJ-45 - Standard 8-wire connectors for IEEE 802.3 10BASE-T networks. RMO N - Remote Monitoring. Subset of SNMP MIB II, which allows monitoring and management capabilities by addressing up to ten different groups of information. 32
