Using Zoning Zone configurations can be any of the following: Defined This is the complete set of all zone objects that have been defined in the fabric. When zone objects are defined, the information initially resides in RAM; it must be saved to ensure that it is saved to flash memory and is not lost during power down or when a new zone configuration is enabled. Changes replicate to all switches in the fabric whenever the zone information is changed. Changes must be saved to flash memory to be committed to persistent store (that is, to remain across reboot). Enabled This is the zone configuration that is active. It resides in RAM and it must be saved to ensure that it is not lost when a new configuration is enabled or when power is down. Any changes replicate to all switches in the fabric when the configuration is enabled or saved. Use the cfgEnable command to enable a zone configuration, to initiate cfgSave, and to propagate zoning throughout the fabric. Disabled Use the cfgDisable command to disable a zoning configuration, to initiate cfgSave to save the zoning configuration to flash memory, and to propagate the zoning configuration throughout the fabric. Saved This is the zone configuration that was last saved. It resides in flash memory and it is persistent. In Figure 2, Config5 is defined (created). When it is defined, it resides only in RAM. To transfer it to flash memory to be permanently stored and accessible across reboots, it must be saved. This can be accomplished by either of the following: ■ Saving it directly to flash memory (the recommended method) ■ Enabling it first, then saving it to flash memory. Until it is saved to flash memory, it is not permanently stored and available across reboots. In Figure 2, only the enabled configuration (in the shaded area) is enforced.
