Rresilient Llink
– 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. 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.
Switch
– A device that filters, forwards, and floods packets based on the packet’s
destination address. The Switch learns the addresses associated with each switch port
and builds tables based on this information to be used for the switching decision.
TCP/IP
– A layered set of communications protocols providing Telnet terminal
emulation, FTP file transfer, and other services for communication among a wide range
of computer equipment.
Telnet
– A TCP/IP application protocol that provides virtual terminal service, letting a
user log in to another computer system and access a host as if the user were
connected directly to the host.
TFTP
– Trivial File Transfer Protocol. Allows you to transfer files (such as software
upgrades) from a remote device using your switch’s local management capabilities.
UDP
– User Datagram Protocol. An Internet standard protocol that allows an
application program on one device to send a datagram to an application program on
another device.
VLAN
–
Virtual LAN. A group of location- and topology-independent devices that
communicate as if they are on a common physical LAN.
VLT
–
Virtual LAN Trunk. A Switch-to-Switch link which carries traffic for all the VLANs
on each Switch.
VT100
–
A type of terminal that uses ASCII characters. VT100 screens have a text-
based appearance.
