Step 2 Set the operation mode to enhanced zoning mode. By doing so, 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.
After moving from basic zoning to enhanced zoning, we recommend that you save the running

configuration.

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:
Verify that the active and full zone set do not contain any configuration that is specific to the enhanced
Step 1
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

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, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# zone mode enhanced vsan 3000
Set zoning mode command initiated. Check zone status
switch(config)# no zone mode enhanced vsan 150
Set zoning mode command initiated. Check zone status

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.
