1. In privileged EXEC mode, enter the configure terminal command to enter global configuration
mode.
2. Enter the no zoning defined-configuration cfg command and the name of the zone configuration
you want to delete.
3. Enter the zoning enabled-configuration cfg-action cfg-save command to save the modified
defined configuration to nonvolatile memory.
Example of deleting a zone configuration:
switch# configure terminal
Entering configuration mode terminal
switch(config)# no zoning defined-configuration cfg cfg2
switch(config)# zoning enabled-configuration cfg-action cfg-save
NOTE
If you try to delete the enabled configuration from the defined configuration, the zoning enabled-
configuration cfg-action cfg-save command returns an error. However, if you commit the
transaction with the zoning enabled-configuration cfg-action cfg-disable command, the operation
proceeds without error.
Clearing changes to a zone configuration
The following procedure aborts all pending transactions and removes all uncommitted operations from
the database. It returns the configuration in volatile memory to the state it was in when a zoning
enabled-configuration cfg-action cfg-save or zoning enabled-configuration cfg-name command
was last executed successfully.
1. In privileged EXEC mode, enter the configure terminal command to enter the global configuration
mode.
2. Enter the zoning enabled-configuration cfg-action cfg-transaction-abort command.
Example of aborting a transaction:
switch# configure terminal
Entering configuration mode terminal
switch(config)# zoning enabled-configuration cfg-action cfg-transaction-abort
Clearing all zone configurations
The following procedure clears all zone configurations from the defined configuration and enables the
default zone.
NOTE
For fabrics with many devices, Brocade recommends setting the default access mode to No Access
before clearing all zone configurations to avoid RSCN storms.
1. In privileged EXEC mode, enter the configure terminal command to enter global configuration
mode.
2. Enter the zoning enabled-configuration cfg-action cfg-clear command.
3. Enter one of the following commands, depending on whether an enabled zone configuration exists:
