Glossary
A
ACC Accept link service reply. The normal reply to an Extended Link Service request (such as FLOGI),
indicating that the request has been completed.
ACL (Access Control List)
active copper A Fibre Channel connection that allows copper cabling up to 33 meters (36 yards) between devices.
AD0 A special administrative domain. When an AD-capable switch is first added to a fabric, all relevant
resources of the fabric (switches, ports, devices) become its members automatically. These resources
are put in an implicit list as defined later. When members are added to AD0 explicitly they become part
of the explicit list as fixed members. See also administrative domain, automatic member, explicit list,
fixed member and implicit list.
AD255 An administrative domain that allows users to get an unfiltered view of the fabric and manage ADs. See
also physical fabric.
The difference between the legacy physical fabric context and the physical fabric context as seen from
an AD-capable switch is as follows:
Does not allow modifications to the zone database
Displays hierarchical zone database: AD/zone, and so on
Allows AD administration
address
identifier
A 24-bit or 8-bit value used to identify the source or destination of a frame. See also D_ID, and S_ID.
administrative
domain
(Admin Domain or AD) Part of Brocade’s virtual fabric strategy, a filtered administrative view of the
fabric. The logical view presented in an Admin Domain filters attributes of switch ports and end devices
based on AD membership without hiding the following resources—fabric, chassis, switches, and slots.
Administrative domains allow device resources in a fabric to be grouped together into logical groups
and provide the ability to manage them separately.
Advanced
zoning
In EZSwitchSetup, a zoning option that allows you to customize zoning (appropriate for advanced SAN
administrators who have the experience to perform manual zoning). See also Custom zoning and
Typical zoning.
AD zone
database
The zone database owned by each Admin Domain. Once Fabric OS v5.2.0 is installed, the root zone
database will be owned by AD0. Each AD will have its own zone database (with both defined and
effective zone sets and all related zone objects (zones, zone aliases, zone members). See also AD0 and
root zone database.
