Glossary
Public NL_Port
An NL_Port that logs into the fabric, can function within either a public or a private loop, and
can communicate with either private or public NL_Ports.
Public Device
A device that can log into the fabric and support 20-bit addresses (or has 20-bit phantom
addresses created for it by the switch).
Public Loop
An arbitrated loop that includes a participating FL_Port, and may contain both public and
private NL_Ports.
QuickLoop
A feature that makes it possible to allow private devices within loops to communicate with
public and private devices across the fabric through the creation of a larger loop.
May also refer to the arbitrated loop created using this software. A QuickLoop can contain a
number of devices or looplets; all devices in the same QuickLoop share a single AL_PA
space.
R_A_TOV
Resource Allocation Time-out Value; the maximum time a frame can be delayed in the fabric
and still be delivered.
Route
As applies to a fabric, the communication path between two switches. May also apply to the
specific path taken by an individual frame, from source to destination.
Routing
The assignment of frames to specific switch ports, according to frame destination.
RR_TOV
Resource Recovery Time-out Value; the minimum time a target device in a loop waits after a
LIP before logging out a SCSI initiator.
RSCN
Registered State Change Notification; a switch function that allows notification of fabric
changes to be sent from the switch to specified nodes.
RX_ID
Responder Exchange Identifier. A 2-byte field in the frame header used by the responder of
the Exchange to identify frames as being part of a particular exchange.
