Documentation updates for Fabric OS v6.4.0 and later
Zoning enforcement
Zoning enforcement describes a set of predefined rules that the switch uses to determine where to
send incoming data. Fabric OS uses hardware-enforced zoning. Hardware-enforced zoning means
that each frame is checked by hardware (the ASIC) before it is delivered to a zone member and is
discarded if there is a zone mismatch. When hardware-enforced zoning is active, the Fabric OS
switch monitors the communications and blocks any frames that do not comply with the effective
zone configuration. The switch performs this blocking at the transmit side of the port on which the
destination device is located.
There are two methods of hardware enforcement:
The method used depends on how the zones are configured.
A zone can contain all WWNs, or all D,I members, or a combination of WWN and D,I members.
Frame-based hardware enforcement is in effect if all members of a zone are identified the same
way, either using WWNs or D,I notation, but not both. If the zone includes aliases, then the aliases
must also be defined the same way as the zone.
Session-based hardware enforcement is in effect if the zone has a mix of WWN and D,I members.
If a port is in multiple zones, and is defined by WWN in one zone and by D,I in another, then
session-based hardware enforcement is in effect.

Frame-based hardware enforcement
Session-based hardware enforcement
TI over FCR is supported on an edge switch only in Brocade Native Mode (interopmode 0).
The maximum zone database size is 1 MB and is a combination of the active configuration
size and the defined configuration size. For example, if the active configuration size is
200 KB, then the size of the defined configuration cannot exceed 800 KB.
