Creating and Modifying Zoning Configurations
You can store a number of zones in a zoning configuration database. The maximum number of items
that can be stored in the zoning configuration database depends on the following criteria:
• Number of switches in the fabric.
• Whether or not interoperability mode is enabled.
• Number of bytes per item. The number of bytes required for an item depends on the specifics of the
fabric, but cannot exceed 64 bytes per item.
When enabling a new zone configuration, you must ensure that the size of the configuration does not
exceed the minimum size supported by all switches in the fabric. This is particularly important if and
when you downgrade to a FOS that supports a smaller zone database than the current FOS. In this
scenario, the zone database in the current FOS would have to be changed to the smaller zone database
before the downgrade.
You can use the cfgSize command to check both the maximum available size and the currently saved
size on all switches. Refer to the Fabric OS Command Reference Manual for details on the cfgSize
command. If you believe you are approaching the maximum, you can save a partially completed zoning
configuration and use the cfgSize command to determine the remaining space.
For important considerations for managing zoning in a fabric, and more details about the maximum
zone database size for each version of the FOS, refer to “Maintaining Zone Objects” on page 13-22.
To create a zoning configuration
1. Connect to the switch and log in as admin.
2. Enter the cfgCreate command.
3. Enter the cfgSave command to save the change to the defined configuration.
