Port_Zone1 WWN_Zone1 Port_Zone2 Core Switch WWN_Zone2 Zone Boundaries Figure 12 Hardware-enforced overlapping zones 22.3b(13.3) Any zone using a mixed zoning scheme on the Fabric OS 2-Gbps platform relies on name server authentication as well as hardware-assisted (ASIC) authentication. Hardware-assisted authentication ensures that any PLOGI, ADISC, PDISC, or ACC from an unauthorized device is rejected if that device is attempting to access a device that is not in the same zone. Fabric OS 2-Gbps switches always deploy the hardware assist, in any zone configuration (see Figure 13 and Figure 14).
