POST
Power On Self Test. An internal test that a Switch carries out when it is
powered-up.
QoS Profile
Consists of multiple sets of rules (classifier plus service level
combinations). The QoS profile is assigned to a port(s).
protocol
A set of rules for communication between devices on a network. The
rules dictate format, timing, sequencing and error control.
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.
RPS
Redundant Power System. A device that provides a backup source of
power when connected to a Switch.
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.
Service Levels
Once traffic is classified, service levels can be applied to determine how
the Switch treats classified packets. The Switch offers some predefined
