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

E_port

,

F_port

,

U_Port

.

hard address

The AL_PA that an NL_Port attempts to acquire during loop

initialization. See also

defined zone configuration

.

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

E_D_TOV

.

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: 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.

See also

non-participating mode

.

latency

The 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

With respect to FC, a physical connection between two ports,

consisting of both transmit and receive fibers.

link services

A protocol for link-related actions.
