with full-stops (periods), and is made up of a network section, an
optional subnet section and a host section.
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. Subset of SNMP MIB II which allows monitoring
and management capabilities by addressing up to ten different groups
of information.
RPS Redundant Power System. Part of the SuperStack II product range,
provides a backup source of power when connected to the Switch.
