Rapid Spanning Tree
Protocol
An enhanced version of the Spanning Tree Protocol that allows faster
determination of Spanning Tree topology throughout the bridged
network.
repeater A simple device that regenerates LAN traffic so that the transmission
distance of that signal can be extended. Repeaters are used to connect
two LANs of the same network type.
resilient link A pair of ports that can be configured so that one takes over data
transmission should the other fail. See also main port and standby port.
RMON IETF Remote Monitoring MIB. A MIB that allows you to remotely
monitor LANs by addressing up to nine different groups of information.
router A router is a device on your network which is used to forward IP
packets to a remote destination. An alternative name for a router is a
gateway.
RSTP See Rapid Spanning Tree Protocol.
SAP Service Access Point. A well-defined location that identifies the user of
services of a protocol entity.
segment A section of a LAN that is connected to the rest of the network using a
switch or bridge.
server A computer in a network that is shared by multiple endstations. Servers
provide endstations with access to shared network services such as
computer files and printer queues.
SMTP Simple Mail Transfer Protocol. An IETF standard protocol used for
transferring mail across a network reliably and efficiently (as defined in
RFC 821).
SNMP Simple Network Management Protocol. The current IETF standard
protocol for managing devices on an TCP/IP network.
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 ensure that redundant paths are disabled when the main paths are
operational and enabled if the main paths fail.
standby port The port in a resilient link that takes over data transmission if the main
port in the link fails.
