Chapter 1 Configuring and Managing Zones
Enhanced Zoning
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.
To enable enhanced zoning in a VSAN, perform this task:
Modifying the Zone Database
Modifications to the zone database is done within a session. A session is created at the time of the first
successful configuration command. On creation of a session, a copy of the zone database is created. Any
changes done within the session are performed on this copy of the zoning database. These changes in the
copy zoning database are not applied to the effective zoning database until you commit the changes.
Once you apply the changes, the session is closed.
