Glossary

 

 

include frame delimiters (which mark frame boundaries and describe

 

 

frame contents), primitive signals (indicate events), and primitive

 

 

sequences (indicate or initiate port states).

 

 

P

Participating mode

Mode in which an L_Port in a loop has valid AL_PA and can

 

 

arbitrate, send frames, and retransmit received transmissions. See

 

 

also Non-participating mode.

Phantom

device

Device not physically in a loop but logically included by phantom

 

 

address.

Phantom address

AL_PA value assigned to device not physically in loop. Also called

 

 

phantom AL_PA.

 

PLOGI

Port Login. Port-to-port login process by which initiators establish

 

 

sessions with targets. See also FLOGI.

Point-to-point

Two fibre channel devices connected by a direct link. See also

 

 

Topology.

Port_Name

Unique FC identifier for port, communicated during login and port

 

 

discovery.

 

POST

Power On Self Test. Series of self-tests run after a switch is rebooted

 

 

or reset.

Private

NL_Port

NL_Port that does not log into the fabric and communicates only

 

 

with private NL_Ports in same loop.

Private device

Device that supports arbitrated loop protocol and understands 8-bit

 

 

addresses, but cannot log into fabric.

Private loop

An arbitrated loop with no fibre channel attachment.

 

Protocol

A defined method and standards for communication.

Public

NL_Port

NL_Port that logs into the fabric, can function within public or

 

 

private loops, and can communicate with public or private NL_Ports.

Public device

Device that supports arbitrated loop protocol, understands 8-bit

 

 

addresses, and can log into fabric.

Public loop

An arbitrated loop attached to a switch.
