FL_Port Fabric loop port. A port that is able to transmit under fabric protocol and also has
arbitrated loop capabilities. Can be used to connect an NL_Port to a switch.
FRU Field-Replaceable Unit. A component that can be replaced on site.
FS Fibre Channel Service. A service that is defined by Fibre Channel standards and
exists at a well-known address. For example, the Simple Name Server is a Fibre
Channel service.
FSP Fibre Channel service protocol. The common protocol for all fabric services,
transparent to the fabric type or topology.
FSPF Fabric shortest path first. HP’s routing protocol for Fibre Channel switches.
Fx_Port A fabric port that can operate as either an F_Port or FL_Port.
G_Port Generic port. A port that can operate as either an E_Port or F_Port. A port is
defined as a G_Port when it is not yet connected or has not yet assumed a specific
function in the fabric.
hard address The AL_PA that an NL_Port attempts to acquire during loop initialization.
idle Continuous transmission of an ordered set over a Fibre Channel link when no data
is being transmitted, to keep the link active and maintain bit, byte, and word
synchronization.
integrated fabric The fabric created by connecting multiple HP switches with multiple ISL cables, and
configuring the switches to handle traffic as a seamless group.
ISL trunking The distribution of traffic over the combined bandwidth of multiple ISLs. A set of
trunked ISLs is called a trunking group, and the ports in a trunking group are called
trunking ports.
isolated E_Port An E_Port that is online but not operational due to overlapping Domain IDs or
nonidentical parameters (such as E_D_TOVs).
K28.5 A special 10-bit character used to indicate the beginning of a transmission word
that performs Fibre Channel control and signaling functions. The first seven bits of
the character are the comma pattern.
kernel flash Flash (temporary) memory connected to the peripheral bus of the processor, and
visible within the processor's memory space. Also known as user flash.
L_Port Loop port. A node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop
capabilities. An L_Port can be in one of two modes:
Fabric mode: F Connected to a port that is not loop capable, and using fabric
protocol.
Loop mode: In an arbitrated loop and using loop protocol. An L_Port in loop mode
can also be in participating mode or non-participating mode.
latency The period of time required to transmit a frame, from the time it is sent until it arrives.
Together, latency and bandwidth define the speed and capacity of a link or system.
link As applies to Fibre Channel, a physical connection between two ports, consisting of
both transmit and receive fibres.
link services A protocol for link-related actions.
