Example of Inconsistent defined and effective configuration warning to use
switch: admin> zoneShow
Defined configuration:
cfg: cfg1 zone1; zone2
zone: zone1 10:00:00:00:00:00:00:01; 10:00:00:00:00:00:00:02
zone: zone2 1,1; 1,2
Effective configuration:
cfg: cfg1
zone: zone1 10:00:00:00:00:00:00:01
10:00:00:00:00:00:00:02
zone: zone2 1,1; 1,2
switch: admin> zoneadd zone1, 10:00:00:00:00:00:00:03
switch: admin> cfgsave
WARNING!!!
The changes you are attempting to save will render the
Effective configuration and the Defined configuration inconsistent.
The inconsistency will result in different Effective Zoning
configurations for switches in the fabric if a zone merge or
HA failover happens. To avoid inconsistency it is recommended to
commit the configurations using the 'cfgenable' command.
Do you want to proceed with saving the Defined zoning
configuration only? (yes, y, no, n): [no] y

switch:admin> zoneShow
Defined configuration:
cfg: cfg1 zone1; zone2
zone: zone1 10:00:00:00:00:00:00:01; 10:00:00:00:00:00:00:02; 10:00:00:00:00:00:00:03
zone: zone2 1,1; 1,2
Effective configuration:

zone: zone1 10:00:00:00:00:00:00:01; 10:00:00:00:00:00:00:02
zone: zone2 1,1; 1,2
Default zoning mode
The default zoning mode controls device access if zoning is not implemented or if there is no effective zone configuration. The default
zoning mode has two options:
∙ All Access -- All devices within the fabric can communicate with all other devices.
∙ No Access -- Devices in the fabric cannot access any other device in the fabric.
The default zone mode applies to the entire fabric, regardless of switch model.
The default setting is "All Access".
Typically, when you disable the zoning configuration in a large fabric with thousands of devices, the name server indicates to all hosts
that they can communicate with each other. Each host can receive an enormous list of PIDs, and ultimately cause other hosts to run out
of memory or crash. To ensure that all devices in a fabric do not see each other during a configuration disable operation, set the default
zoning mode to No Access.
NOTE
For switches in large fabrics, the default zone mode should be set to No Access. You cannot disable the effective configuration
if the default zone mode is All Access and you have more than 120 devices in the fabric.
