The unique identifier assigned to a Fibre Channel port. Communicated during login and
port discovery.
POST
Power On Self-Test
; a
series of tests run by a switch after it is turned on.
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
