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 FC topology where ports use arbitration to establish a point-to-point circuit
Arbitrated Loop
Physical Address
(AL_PA)
A unique one-byte value assigned during loop initialization to each NL_Port on a
loop
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 which multiplexes frames at frame boundaries to or from one or more
N_Ports wit h acknowledgment provided
Class 3 service A service which 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

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 McDATA Element Manager. Switch management application that is accessible
through the High Availability Fabric Manager (HAFM).

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
