3. Enter the zoning enabled-configuration cfg-action cfg-save or zoning enabled-configuration
cfg-name command to commit the ongoing transaction and save the access mode change to
nonvolatile memory.
4. Enter the show running-config zoning enabled-configuration command to verify the access mode
change.
Example of setting the default zoning mode to no access:
switch# configure terminal
Entering configuration mode terminal
switch(config)# zoning enabled-configuration default-zone-access noaccess
switch(config)# zoning enabled-configuration cfg-action cfg-save
switch(config)# do show running-config zoning enabled-configuration
zoning enabled-configuration cfg-name cfg1
zoning enabled-configuration default-zone-access noaccess
zoning enabled-configuration cfg-action cfg-save
Understanding and managing zone database size
The maximum size of a zone database is the upper limit for the defined configuration, and it is
determined by the amount of memory available for storing the master copy of the defined configuration
in flash memory.
Use the following information displayed by the show zoning operation-info command to determine
whether there is enough space to complete outstanding transactions:
• db-max — Theoretical maximum size of the zoning database kept in nonvolatile memory
• db-avail — Theoretical amount of free space available
• db-committed — The size of the defined configuration currently stored in nonvolatile memory
• db-transaction — The amount of memory required to commit the current transaction
The supported maximum zone database size is 100 KB. If the outstanding transaction data (db-
transaction field) is less than the remaining supported space (100 KB minus db-committed), enough
space exists to commit the transaction.
NOTE
The db-max field has a theoretical zone database limit of approximately 1 MB. However, performance
might become unacceptable if the zoning database exceeds 150 KB.
Viewing database size information
In privileged EXEC mode, enter the show zoning operation-info command.
Database and transaction size information is displayed in bytes.
switch# show zoning operation-info
db-max 1045274
db-avail 1043895
db-committed 367
db-transaction 373
transaction-token 1
last-zone-changed-timestamp 2011-11-16 16:54:31 GMT-7:00
last-zone-committed-timestamp 2011-11-16 16:23:44 GMT-7:00
Managing zone aliases
A zone alias is user-defined name for a logical group of ports or WWNs. You can simplify the process of
creating and managing zones by first specifying aliases for zone members. Aliases facilitate tracking
and eliminate the need for long lists of individual zone member names. An alias can be a member of a
zone, but it cannot be a member of a zoning configuration.
