latency
The time required to transmit a frame from the time it is sent until it arrives.
Together, latency and bandwidth de
fi
ne the speed and capacity of a link or
system.
link
With respect to FC, a physical connection between two ports, consisting of
both transmit and receive
fi
bers.
link services
A protocol for link-related actions.
LIP
Loop initialization primitive. The signal that begins initialization in a loop. It
indicates either loop failure or the resetting of a node.
LM_TOV
Loop master time-out value. The minimum time that the loop master waits for a
loop initialization sequence to return.
loop failure
Loss of signal within a loop for any period of time; loss of synchronization for
longer than the time-out value.
Loop_ID
A hexadecimal value representing one of the 127 possible AL_PA values in an
arbitrated loop.

loop initialization
The logical procedure used by an L_Port to discover its environment. Can be
used to assign AL_PA addresses, detect loop failure, or reset a node.

LPSM
Loop port state machine. The logical entity that performs arbitrated loop
protocols and de
fi
nes the behavior of L_Ports when they require access to an
arbitrated loop.

LWL
Long wavelength. A type of
fi
ber optic cabling that is based on 1300 mm
lasers and supports link speeds up to 2 Gb/s. May also refer to the type of
transceiver.

master port
The port that determines the routing paths for all traf
fi
c
fl
owing through a
trunking group. One of the ports in the
fi
rst ISL in the trunking group is
designated as the master port for that group.

MIB
Management Information Base. An SNMP structure to help with device
management, providing con
fi
guration and device information.

multicast
The transmission of data from a single source to multiple speci
fi
ed N_Ports (as
opposed to all ports on the network).
N_Port
Node port. A port on a node that can connect to an FC port or to another
N_Port in a point-to-point connection.
name server
A term frequently used to indicate a Simple Name Server (SNS).

NL_Port
Node loop port. A node port that has arbitrated loop capabilities. Used to
connect an equipment port to the fabric in a loop con
fi
guration through an
FL_Port.

.
node
An FC device that contains an N_Port or NL_Port.
non-participating
mode
A mode in which an L_Port in a loop is inactive and cannot arbitrate or send
frames, but can retransmit any received transmissions. This mode is entered if
there are more than 127 devices in a loop and an AL_PA cannot be acquired.

Nx_Port
A node port that can operate as an N_Port or NL_Port.
Onboard
Administrator
(OA)
The HP BladeSystem Onboard Administrator (OA) is the enclosure management
processor, subsystem, and
fi
rmware base used to support the HP BladeSystem
c7000 or HP BladeSystem c3000 and all the managed devices contained
within the enclosure.
