FLOGI The process by which a n N_Por t 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 b e replaced on site.

FS Fibre Channel Service. A service that is deﬁned by FC standards and exists at a

well-known a d dress. 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_Por t or FL_Port.

G_Port Generic port. A port that can operate as an E _Port or F_Port. A p ort is d eﬁned

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 a ctive and maintain bit, byte, and word

synchronization.

integrated fabric The fabric created by connecting multiple HP switches with multiple ISL cables,

and con ﬁguring the switches to handle trafﬁcasaseamlessgroup.

ISL trunking The distribution of trafﬁc over the combined bandwidth of multiple ISLs. A set

oftrunkedISLsiscalledatrunking group; the ports in a trunking group are

called trunking ports.

isolated E_Port An E_Por t 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) mem ory connected to the peripheral bus of the processor and

visible within the p rocessor's memory space. Also called a user

ﬂash.

L_Port Loop por t. A node port (NL_Port) or fabric por t (FL_Port) that has arbitrated loop

capabilities. An L_Port can be in one of two modes:

• Fabric mode: Connected to a port that is not loop capable a nd 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.
