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 A 24-bit or 8-bit value used to identify the source or destination of a frame. See also D_ID, and S_ID. identifier 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.
