Safe zone Safe zoning is a fabric-wide parameter that ensures that the resulting zone set of two merged fabrics is consistent with the pre-merged zone sets. When you enable Safe zone, the Default Zone must be disabled and the zoning configuration of neighboring switches must match completely before the zoning can merge. To allow a Brocade switch into an M-EOS Native fabric, safe zoning must be disabled. This allows the Brocade switch to join the fabric although the zone sets do not match. After the fabric merge and zone merge are completed, safe zoning may be re-enabled. Activating zone configurations on a standalone switch To activate zone configurations on a standalone switch: 1. Connect to the switch and log in as admin. 2. Enter the interopmode command with the appropriate option to activate the zone, for example: InteropMode [0|2|3 [-z McDataDefaultZone] [-s McDataSafeZone]] 0: to turn interopMode off 2: to turn McData Fabric mode on Valid McDatatDefaultZone: 0 (disabled), 1 (enabled) Valid McDataSafeZone: 0 (disabled), 1 (enabled) 3: to turn McDATA Open Fabric mode on Activating zone configurations fabric-wide To activate zoning fabric-wide: 1. Connect to the switch and log in as admin. 2. Enter the cfgmcdtmode command with the appropriate option, for example cfgmcdtmode [--enable | --disable | --help] [safezoning | defaultzoning] cfgmcdtmode --enable safezoning safezoning McDATA mode has been enabled ... NOTE: The interopmode and cfgMcdtmode commands perform the same functions. The interopmode command only affects the local configuration and the command must be issued on each switch in the fabric. The cfgMcdtmode affects the entire fabric. Verifying the effective zone configuration An effective zone configuration is a subset of the defined zone configuration, containing only the zone configuration objects that are currently enabled; only one configuration can be active at a time, but multiple configurations can be defined in the database. You must verify that the active zone set or zone configuration has correctly propagated to the other switches in the fabric. You can enter the cfgenable command with the name of the zone configuration to activate the effective zone configuration and the cfgdisable command with the name of the zone configuration to deactivate the effective zone configuration. When uploading and downloading configuration files, you must be sure that the file being moved contains the correct information. After a configuration is committed, any inaccurate parameters must be manually corrected. In McDATA Fabric mode, you can set the effective zone configuration to the Defined Database. If the Defined Database contains a configuration with the same name, it will be replaced. Any non-duplicate zone sets or zones will remain unchanged. Before moving the effective zone configuration to the Defined Database, you should view the zoning configuration. Fabric OS 6.x administrator guide 487
