HP SAN manual Glossary

Glossary

Active firmware	The firmware image on the switch that is in use
Active zone set	The zone set that defines the current zoning for the fabric
Activity LED	A port LED that indicates when frames are entering or leaving the port
Administrative state	State that determines the operating state of the port, I/O blade, or switch. The
	configured administrative state is stored in the switch configuration. The configured
	administrative state can be temporarily overridden using the CLI.
AL_PA	Arbitrated Loop Physical Address
Alarm	A message generated by the switch that specifically requests attention. Alarms are
	generated by several switch processes. Some alarms can be configured.
Arbitrated loop	An Fibre Channel topology where ports use arbitration to establish a point-to-point
	circuit
Arbitrated Loop	A unique one-byte value assigned during loop initialization to each NL_Port on a
Physical Address	loop
(AL_PA)
ASIC	Application Specific Integrated Circuit
Auto Save	Zoning parameter that determines whether changes to the active zone set that a
	switch receives from other switches in the fabric will be saved to permanent memory
	on that switch
BootP	A type of network server
Buffer credit	A measure of port buffer capacity equal to one frame
Cascade topology	A fabric in which the switches are connected in series. If you connect the last switch
	back to the first switch, you create a cascade-with-a-loop topology.
CHAP	Challenge Handshake Authentication Protocol
Class 2 service	A service that multiplexes frames at frame boundaries to or from one or more
	N_Ports wit h acknowledgment provided
Class 3 service	A service that multiplexes frames at frame boundaries to or from one or more
	N_Ports without acknowledgment

Configured zone sets The zone sets stored on a switch.

DefaultZone	Enables (True) or disables (False) communication among ports/devices that are not
	defined in the active zone set or when there is no active zone set. This parameter
	applies only when interop mode is set to McDATA Fabric Mode.
Device Security	A component of fabric security that provides for the authorization and
	authentication of devices that attach to a switch through the use of groups and
	security sets
Domain ID	User defined number that identifies the switch in the fabric
EFCM	Enterprise Fabric Connectivity Manager
Element Manager	Switch management application that is accessible through the High Availability
	Fabric Manager (HAFM).
Event log	Log of messages describing events that occur in the fabric
Expansion port	E_Port that connects to another FC-SW-2 compliant switch
Fabric database	The set of fabrics that have been opened during a McDATA Web Server session
Fabric management	The switch through which the fabric is managed (the switch connected to the
switch	Ethernet network)
Fabric name	User defined name associated with the file that contains user list data for the fabric
Fabric port	An F_Port
