Configuring the zoning database
Use the Zoning Config dialog, shown in Figure 12, to change the Merge Auto Save,
Default Zone, and Discard Inactive configuration parameters. Open the Zoning
menu and select Edit Zoning Config to open the Zoning Config dialog. After
making changes, click the OK button to put the new values into effect.

Merge auto save The Merge Auto Save parameter determines whether changes to
the active zone set that a switch receives from other switches in the fabric will be
saved to the zoning database on that switch. Changes are saved when an updated
zone set is activated. Zoning changes are always saved to temporary memory.
However, if Merge Auto Save is enabled, the switch firmware saves changes to the
active zone set in temporary memory and to the zoning database. If Merge Auto
Save is disabled, changes to the active zone set are stored only in temporary
memory, which is cleared when the switch is reset.
Notes:
Disabling the Merge Auto Save parameter can be useful to prevent the propagation
of zoning information when experimenting with different zoning schemes.
However, leaving the Merge Auto Save parameter disabled can disrupt device
configurations should a switch have to be reset. For this reason, the Merge Auto
Save parameter should be enabled in a production environment.
Default zone The Default Zone parameter enables (True) or disables (False)
communication among ports/devices that are not defined in the active zone set or
when there is no active zone set. This parameter must have the same value
throughout the fabric.
Discard inactive The Discard Inactive parameter automatically removes inactive
zones and zone sets when a zone set is activated or deactivated from a remote
switch.
