Chapter 38 Configuring and Managing Zones
Enhanced Zoning
Changing from Basic Zoning to Enhanced Zoning
To change to the enhanced zoning mode from the basic mode, perform this task:
Step 1 Verify that all switches in the fabric are capable of working in the enhanced mode.
If one or more switches are not capable of working in enhanced mode, then your request to move to
enhanced mode is rejected.
Step 2 Set the operation mode to enhanced zoning mode.
You will automatically start a session, acquire a fabric wide lock, distribute the active and full zoning
database using the enhanced zoning data structures, distribute zoning policies and then release the lock.
All switches in the fabric then move to the enhanced zoning mode.
Tip After moving from basic zoning to enhanced zoning, we recommend that you save the running
configuration.
Changing from Enhanced Zoning to Basic Zoning
Cisco SAN switches allow you to change from enhanced zoning to basic zoning to enable you to
downgrade and upgrade to other Cisco NX-OS releases.
To change to the basic zoning mode from the enhanced mode, perform this task:
Step 1 Verify that the active and full zone set do not contain any configuration that is specific to the enhanced
zoning mode.
If such configurations exist, delete them before proceeding with this procedure. If you do not delete the
existing configuration, the switch software automatically removes them.
Step 2 Set the operation mode to basic zoning mode.
You will automatically start a session, acquire a fabric-wide lock, distribute the zoning information using
the basic zoning data structure, apply the configuration changes and release the lock from all switches
in the fabric. All switches in the fabric then move to basic zoning mode.
Enabling Enhanced Zoning
By default, the enhanced zoning feature is disabled in all switches in the Cisco Nexus 5000 Series.
