11 Zoning overview Zone configuration naming is flexible. One configuration should be named PROD_fabricname, where fabricname is the name that the fabric has been assigned. The purpose of the PROD configuration is to easily identify the configuration that can be implemented and provide the most generic services. If other configurations are used for specialized purposes, names such as "BACKUP_A," "RECOVERY_2," and "TEST_18jun02" can be used. Zone configurations A zone configuration is a group of one or more zones. A zone can be included in more than one zone configuration. When a zone configuration is in effect, all zones that are members of that configuration are in effect. Several zone configurations can reside on a switch at once, and you can quickly alternate between them. For example, you might want to have one configuration enabled during the business hours and another enabled overnight. However, only one zone configuration can be enabled at a time. The different types of zone configurations are: • Defined Configuration The complete set of all zone objects defined in the fabric. • Effective Configuration A single zone configuration that is currently in effect. The effective configuration is built when you enable a specified zone configuration. • Saved Configuration A copy of the defined configuration plus the name of the effective configuration, which is saved in flash memory. (You can also provide a backup of the zoning configuration and restore the zoning configuration.) There might be differences between the saved configuration and the defined configuration if you have modified any of the zone definitions and have not saved the configuration. • Disabled Configuration The effective configuration is removed from flash memory. When you disable the effective configuration, the Advanced Zoning feature is disabled on the fabric, and all devices within the fabric can communicate with all other devices (unless you previously set up a default zone, as described in "Default zoning mode" on page 236). This does not mean that the zoning database is deleted, however, only that there is no configuration active in the fabric. On power-up, the switch automatically reloads the saved configuration. If a configuration was active when it was saved, the same configuration is reinstated on the local switch. Zoning enforcement Zoning enforcement describes a set of predefined rules that the switch uses to determine where to send incoming data. There are two methods of enforcement: • Frame-based hardware enforcement • Session-based hardware enforcement 226 Fabric OS Administrator's Guide 53-1001336-01
