Enhanced Zoning Chapter 30 Configuring and Managing Zones Send documentation comments to [email protected] 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 30-40 • Changing from Basic Zoning to Enhanced Zoning, page 30-41 • Changing from Enhanced Zoning to Basic Zoning, page 30-41 • Enabling Enhanced Zoning, page 30-42 • Creating Attribute Groups, page 30-42 • Merging the Database, page 30-42 • Analyzing a Zone Merge, page 30-43 • Configuring Zone Merge Control Policies, page 30-44 About Enhanced Zoning Table 30-3 lists the advantages of the enhanced zoning feature in all switches in the Cisco MDS 9000 Family. Table 30-3 Advantages of Enhanced Zoning Basic Zoning Enhanced Zoning Enhanced Zoning Advantages 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 Enforces and exchanges the default ensure smooth fabric operation, all switches in the zone setting throughout the fabric. fabric must have the same default zone setting. 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 Enhanced error reporting nature of the problem from each remote eases the troubleshooting switch. 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. 30-40 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
