HP AA979A - StorageWorks SAN Switch 2/8V Installation Manual page 116

An IDLE or ARB ordered set that is transmitted during breaks between data frames to
fill word
keep the fibre channel link active.
Fabric loop port. A port that is able to transmit under fabric protocol and also has
FL_Port
arbitrated loop capabilities. Can be used to connect an NL_Port to a switch.
Field-Replaceable Unit. A component that can be replaced on site.
FRU
Fibre Channel Service. A service that is defined by fibre channel standards and exists at
FS
a well-known address. For example, the Simple Name Server is a fibre channel service.
Fibre channel service protocol. The common protocol for all fabric services, transparent
FSP
to the fabric type or topology.
Fabric shortest path first. HP's routing protocol for fibre channel switches.
FSPF
A fabric port that can operate as either an F_Port or FL_Port.
Fx_Port
G
Generic port. A port that can operate as either an E_Port or F_Port. A port is defined as
G_Port
a G_Port when it is not yet connected or has not yet assumed a specific function in the
fabric.
H
The AL_PA that an NL_Port attempts to acquire during loop initialization.
hard address
I
Continuous transmission of an ordered set over a fibre channel link when no data is
idle
being transmitted, to keep the link active and maintain bit, byte, and word
synchronization.
The fabric created by connecting multiple HP switches with multiple ISL cables, and
integrated fabric
configuring the switches to handle traffic as a seamless group.
The distribution of traffic over the combined bandwidth of multiple ISLs. A set of trunked
ISL trunking
ISLs is called a "trunking group", and the ports in a trunking group are called "trunking
ports".
An E_Port that is online but not operational due to overlapping domain IDs or
isolated E_Port
nonidentical parameters (such as E_D_TOVs).
