376 Administering Advanced Zoning
Figure 25 Hardware-enforced overlapping zones
Any zone using both WWNs and
domain, port entries on the 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. 2 Gbit/sec switches always deploy the hardware assist, in any zone configuration (see
Figure 26 and Figure 27).
Figure 26 Zoning with hardware assist (mixed-port and WWN zones)
Figure 27 Session-based hard Zoning
In Figure 27, only the ports that are overlapped are software-enforced with hardware assist.
