Figure 13-2 shows a fabric with four nonoverlapping hardware-enforced zones.

Figure 13-3 shows the same fabric components zoned in an overlapping fashion.

Any zone using both WWNs and domain, port entries on the Brocade 2 Gbit/sec platform relies on
Name Server authentication as well as hardware-assisted (ASIC) authentication, which ensures that any
PLOGI/ADISC/PDISC/ACC from an unauthorized device attempting to access a device it is not zoned
with is rejected. Brocade 2 Gbit/sec switches always deploy the hardware assist, in any zone
configuration (see Figure 13-4 and Figure 13-5).
