Enhanced Zoning
The zoning feature complies with the FC-GS-4 and FC-SW-3 standards. Both standards support the basic
zoning functionalities explained in the previous section and the enhanced zoning functionalities
described in this section.

Table 30-3 Advantages of Enhanced Zoning
Basic Zoning
Administrators can make simultaneous
configuration changes. Upon activation, one
administrator can overwrite another administrator's
changes.
If a zone is part of multiple zone sets, you create an
instance of this zone in each zone set
The default zone policy is defined per switch. To
ensure smooth fabric operation, all switches in the
fabric must have the same default zone setting.
To retrieve the results of the activation on a per
switch basis, the managing switch provides a
combined status about the activation. It does not
identify the failure switch.
To distribute the zoning database, you must
reactivate the same zone set. The reactivation may
affect hardware changes for hard zoning on the local
switch and on remote switches.

Enhanced Zoning
Performs all configurations within a
single configuration session. When you
begin a session, the switch locks the
entire fabric to implement the change.
References to the zone are used by the
zone sets as required once you define
the zone.
Enforces and exchanges the default
zone setting throughout the fabric.
Retrieves the activation results and the
nature of the problem from each remote
switch.
Implements changes to the zoning
database and distributes it without
reactivation.

Enhanced Zoning Advantages
One configuration session for
the entire fabric to ensure
consistency within the fabric.
Reduced payload size as the
zone is referenced. The size
is more pronounced with
bigger databases.
Fabric-wide policy
enforcement reduces
troubleshooting time.
Enhanced error reporting
eases the troubleshooting
process
Distribution of zone sets
without activation avoids
hardware changes for hard
zoning in the switches.
