Isl trunking – HP Brocade 16Gb SAN Switch for HP BladeSystem c-Class User Manual

FRU
Field-replaceable unit. A component that can be replaced on site.
FS
FC 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
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
,
, and
.
H
hard address
The AL_PA that an NL_Port attempts to acquire during loop initialization. See also
.
I
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 due to nonidentical
parameters (such as E_D_TOVs). See also
K
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
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.
LIP
Loop initialization primitive. The signal that begins initialization in a loop. It indicates either loop
failure or the resetting of a node.
LM_TOV
Loop master time-out value. The minimum time that the loop master waits for a loop initialization
sequence to return.
