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
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.

.
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.
