FLOGI The process by which an N_Port determines whether a fabric is present and, if
so, exchanges service parameters with it. See also ???.
FL_Port Fabric loop port. A port that is able to transmit under fabric protocol and has
arbitrated loop capabilities. Can also be used to connect an NL_Port to a
switch. See also ???.
frame The Fibre Channel structure used to transmit data between ports. Consists
of a start-of-frame delimiter, header, optional headers, data payload, cyclic
redundancy check, and end-of-frame delimiter. There are two types of frames:
link control frames and data frames. See also ???.
FRU Field-replaceable unit. A component that can be replaced on site.
FS Fibre Channel Service. A service that is defined by FC standards and exists at a
well-known address. The Simple Name Server, for example, is an FC service.
FSP Fibre Channel Service Protocol. The common protocol for all fabric services; it is
transparent to the fabric type or topology.
FSPF Fabric shortest path first. HP routing protocol for FC switches.
Fx_Port A fabric port that can operate as an F_Port or FL_Port.
G_Port Generic port. A port that can operate as 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. See also ???, ???, ???.
hard address The AL_PA that an NL_Port attempts to acquire during loop initialization. See
also ???.
idle Continuous transmission of an ordered set over an FC 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; 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). See also ???.
K28.5 A special 10-bit character that indicates the beginning of a transmission word
that performs FC control and signaling functions. The first seven bits are the
common pattern.
kernel flash Flash (temporary) memory connected to the peripheral bus of the processor and
visible within the processor's memory space. Also called a 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:
•
•
See also ???.
Fabric mode: Connected to a port that is not loop capable and is 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.
