Glossary
Port_Name
The unique identifier assigned to a Fibre Channel port. Communicated during login and
port discovery.
POST
Power On Self-Test
Private Device
A device that supports arbitrated loop protocol and can interpret 8-bit addresses, but cannot
log into the fabric.
Private Loop
An arbitrated loop that does not include a participating FL_Port.
Private NL_Port
An NL_Port that communicates only with other private NL_Ports in the same loop and
does not log into the fabric.
Protocol
A defined method and a set of standards for communication.
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). See also Phantom Addresses
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. See also E_D_TOV, RR_TOV.
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. See also FSPF.
