Using QuickLoop Zones QuickLoop Zones QuickLoop zones are hardware enforced. Switch hardware prevents unauthorized data transfer between ports within the zone, allowing devices to be partitioned into zones to restrict system access to selected devices. Once devices are included in a zone, they are visible only to other devices within that zone. QuickLoop zone members are designated by looplet (port number), or by Arbitrated Loop Physical Address (AL_PA).

Using QuickLoop Zones

Zoning Version 3.1.x/4.1.x User Guide
QuickLoop Zones
QuickLoop zones are hardware enforced. Switch hardware prevents unauthorized
data transfer between ports within the zone, allowing devices to be partitioned into
zones to restrict system access to selected devices. Once devices are included in a
zone, they are visible only to other devices within that zone.
QuickLoop zone members are designated by looplet (port number), or by
Arbitrated Loop Physical Address (AL_PA). There are 126 unique AL_PAs per
QuickLoop; therefore, a QuickLoop zone can contain no more than 125 devices.
Note:
Each QuickLoop port uses one AL_PA.
Fabric zones and QuickLoop zones are independent of each other. Both types of
zones can co-exist in the same zone configuration, and QuickLoop devices can be
included within a fabric zone configuration. But, while devices within a
QuickLoop can be seen by a public host, devices within each QuickLoop are only
visible to devices within their own QuickLoop.
In QuickLoop zoning, devices within a QuickLoop can be partitioned off within
that QuickLoop to form QuickLoop zones. In other words, a QuickLoop Zone is a
subset of a QuickLoop and can include only QuickLoop devices.
Note:
QuickLoop is supported in Fabric OS V3.1; however, it is not supported in
Fabric OS V4.1.
