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
