Enhanced Zoning Chapter 30 Configuring and Managing Zones Send documentation comments to [email protected] Note If a switch running Cisco SAN-OS Release 2.0(1b), or later, with enhanced zoning enabled is downgraded to Cisco SAN-OS Release 1.3(4), or earlier, the switch comes up in basic zoning mode and thus cannot join the fabric because all the other switches in the fabric are still in enhanced zoning mode. Enabling Enhanced Zoning By default, the enhanced zoning feature is disabled in all switches in the Cisco MDS 9000 Family. To enable enhanced zoning in a VSAN using Fabric Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Expand a VSAN and then select a zone set in the Logical Domains pane. You see the zone set configuration in the Information pane. Click the Enhanced tab. You see the current enhanced zoning configuration. Set the Action drop-down menu to enhanced to enable enhanced zoning in this VSAN. Click Apply Changes to save these changes. Creating Attribute Groups In enhanced mode, you can directly configure attributes using attribute groups. To configure attribute groups, refer to the Cisco MDS 9000 Family CLI Configuration Guide. Merging the Database The merge behavior depends on the fabric-wide merge control setting: • Restrict-If the two database are not identical, the ISLs between the switches are isolated. • Allow-The two databases are merged using the merge rules specified in Table 30-4. Table 30-4 Database Zone Merge Status Local Database Adjacent Database Merge Status The databases contain zone sets with the same name1 but Successful. different zones, aliases, and attributes groups. The databases contains a zone, zone alias, or zone attribute group object with same name1 but different members. Failed. Results of the Merge The union of the local and adjacent databases. ISLs are isolated. 30-42 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
