IP address: Internet Protocol address. A unique identifier for a device attached to a
network using TCP/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 network.
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
conditions.
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 internal transmit 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.
resilient 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.
RMON: Remote Monitoring. A subset of SNMP MIB II that allows monitoring and
management capabilities by addressing up to ten different groups of information.
RPS: Redundant Power System. A device that provides a backup source of power
when connected to the Switch.
server farm: A cluster of servers in a centralized location serving a large user
population.
SLIP:
Serial Line Internet Protocol. A protocol that allows IP to run over a serial line
connection.
SNMP: Simple Network Management Protocol. A protocol originally designed to be
used in managing TCP/IP internets. SNMP is presently implemented on a wide range
of computers and networking equipment and may be used to manage many aspects of
network and end station operation.
Spanning Tree Protocol (STP): A bridge-based system for providing fault tolerance
on networks. STP works by allowing you to implement parallel paths for network
traffic, and to ensure that redundant paths are disabled when the main paths are
operational and enabled if the main paths fail.
stack:
A group of network devices that are integrated to form a single logical device.
standby port: The port in a resilient link that will take over data transmission if the
main port in the link fails.
