Glossary114
fill word
An IDLE or ARB ordered set that is transmitted during breaks between data frames to
keep the fibre channel link active.
FL_Port Fabric loop port. A port that is able to transmit under fabric protocol and also has
arbitrated loop capabilities. Can be used to connect an NL_Port to a switch.
FRU Field-Replaceable Unit. A component that can be replaced on site.
FS Fibre Channel Service. A service that is defined by fibre channel standards and exists
at a well-known address. For example, the Simple Name Server is a fibre channel
service.
FSP Fibre channel service protocol. The common protocol for all fabric services,
transparent to the fabric type or topology.
FSPF Fabric shortest path first. HP’s routing protocol for fibre channel switches.
Fx_Port A fabric port that can operate as either an F_Port or FL_Port.
G
G_Port Generic port. A port that can operate as either 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.
H
hard address The AL_PA that an NL_Port attempts to acquire during loop initialization.
I
idle Continuous transmission of an ordered set over a fibre channel 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”, and 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).
