Enhanced Zoning
Step 2 Click the Read Only Violations, Statistics tab or the LUN Zoning Statistics tab to view statistics for
the selected zone.
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.
This section includes the following topics:
• About Enhanced Zoning, page 16-29
• Changing from Basic Zoning to Enhanced Zoning, page 16-30
• Changing from Enhanced Zoning to Basic Zoning, page 16-30
• Enabling Enhanced Zoning, page 16-31
• Merging the Database, page 16-31
• Analyzing a Zone Merge, page 16-32
• Configuring Zone Merge Control Policies, page 16-32
About Enhanced Zoning
Table 16-2 lists the advantages of the enhanced zoning feature in all switches in the Nexus 5000 Series.

Administrators can make simultaneous
configuration changes. Upon activation, one
administrator can overwrite another administrator’s
changes.
Performs all configurations within a
single configuration session. When you
begin a session, the switch locks the
entire fabric to implement the change.
One configuration session for
the entire fabric to ensure
consistency within the fabric.
If a zone is part of multiple zone sets, you create an
instance of this zone in each zone set
References to the zone are used by the
zone sets as required once you define
the zone.
Reduced payload size as the
zone is referenced. The size
is more pronounced with
bigger databases.
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.
Enforces and exchanges the default
zone setting throughout the fabric.
Fabric-wide policy
enforcement reduces
troubleshooting time.
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.
Retrieves the activation results and the
nature of the problem from each remote
switch.
Enhanced error reporting
eases the troubleshooting
process
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.
Implements changes to the zoning
database and distributes it without
reactivation.
Distribution of zone sets
without activation avoids
hardware changes for hard
zoning in the switches.
