Glossary

Active zone set The zone set that defines the current zoning for the fabric
Active firmware The firmware image on the switch that is in use
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 Command Line
Interface (CLI).
Alarm A message generated by the switch that specifically requests attention. Alarms are
generated by several switch processes. Some alarms can be configured.
Alias A named set of ports or devices. An alias is not a zone, and can not have a zone or
another alias as a member.
AL_PA Arbitrated Loop Physical Address
An FC topology where ports use arbitration to establish a point-to-point circuit
Arbitrated loop
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 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
Default Visibility Zoning parameter that determines the level of communication among ports/devices
when there is no active zone set. It is recommended that all switches have the same
Default Visibility setting.
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
Discard Inactive A zoning configuration parameter that automatically removes the previously active
zone set when a zone set is activated on a switch (non-configurable, always
enabled)
Configured zone sets The zone sets stored on a switch excluding the active zone set
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
must have the same value throughout the fabric. If interop mode is McDATA Fabric
Mode, the Default Zone parameter is automatically distributed throughout the
fabric. If McDATA 4Gb SAN Switches are in a fabric with other M-Series directors
and edge switches, and the interop mode is Standard/Open Fabric, the Default
Zone parameter MUST be disabled (False) on the McDATA 4Gb SAN Switches for
zoning to function properly.
