Changing from Enhanced Zoning to Basic Zoning

After moving from basic zoning to enhanced zoning, we recommend that you save the running configuration.
Tip
Changing from Enhanced Zoning to Basic Zoning
The standards do not allow you to move back to basic zoning. However, Cisco MDS switches allow this move
to enable you to downgrade and upgrade to other Cisco SAN-OS or Cisco NX-OS releases.
To change to the basic zoning mode from the enhanced mode, follow these steps:
Step 1 Verify that the active and full zoneset 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 Cisco NX-OS software automatically removes them.
Step 2 Set the operation mode to basic zoning mode. By doing so, 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.
Note If a switch running Cisco SAN-OS Release 2.0(1b) and NX-OS 4(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
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 Series.
To enable enhanced zoning in a VSAN, follow these steps:
Step 1
switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# zone mode enhanced vsan 3000
Enables enhanced zoning in the specified VSAN.
Step 3
switch(config)# no zone mode enhanced vsan 150
Disables enhanced zoning in the specified VSAN.

Enabling Enhanced Zoning Using Fabric Manager

To enable enhanced zoning in a VSAN using Fabric Manager, follow these steps:
