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

existing configuration, the Cisco SAN-OS software automatically removes them.
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.
If a switch running Cisco MDS SAN-OS Release 2.0(1b), or later, with enhanced zoning enabled is

and thus cannot join the fabric because all the other switches in the fabric are still in enhanced zoning
mode.

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:
