interopMode 2 interopMode Enables or disables Brocade switch interoperability with McDATA switches. Synopsis interopmode [mode [-z McDataDefaultZone] [-s McDataSafeZone]] Description Use this command to enable or disable Brocade switch interoperability with McDATA switches within a Brocade fabric. Fabric OS v6.0 introduces a new M-EOS compatible McDATA Open Fabric Mode (interopMode 3) on all platforms that support McDATA Fabric Mode (interopmode 2). Open Fabric Mode is intended specifically for adding FOS-based products into M-EOS fabrics that are already using McDATA Open Fabric Mode. Fabrics comprised of only FOS switches in McDATA Open Fabric Mode are not supported, and will not be able to be zoned. All zoning of a mixed M-EOS and FOS fabric operating in McDATA Open Fabric Mode is performed via the M-EOS switches. Notes Interop Mode 1 (former "open" mode) is no longer supported in Fabric OS v6.0. The interopMode command must be executed on all Brocade switches in the fabric. The following restrictions apply when changing Fabric modes: Switches must be disabled (offline) and will automatically reboot after executing the command for Fabric mode changes to take effect. Not all services are available in interop mode. Refer to the Fabric OS Administrator's Guide for details. Zone commands in McDATA Open Fabric Mode (3) are disabled except display commands and two set commands, cfgDisable and cfgClear, which can only be called when the switch is offline. When changing From Brocade Native to McDATA Fabric or McDATA Open Fabric Mode: • McDATA Fabric mode only supports a user domain ID range of 1-31, which is added to the domain offset to get the PID domain range. The domain range for McDATA Open Fabric mode is 97 to 127. The existing preferred configuration needs to be changed to a value within this range before the conversion is allowed.If your domain is out of range, the system makes a best estimate of what the domain should be. For example, if your domain is 0x92, going to McDATA Fabric mode (2)2 will end up at domain 2 (mask out upper bits). Or, when changing to McDATA Open Fabric Mode (3), your domain will end up at 0x62 (98 decimal) - mask out upper bits and add domain offset of 0x60. • Existing zone configurations will be erased. The switch will have to assume the zone configuration from the fabric it joins or a new configuration will have to be configured. When changing from McDATA Fabric or McDATA Open Fabric Mode to Brocade Native Mode: • Existing zone configurations will be erased. The switch will have to assume the zone configuration from the fabric it joins or a new configuration will have to be configured. When changing between McDATA Fabric mode and McDATA Open Fabric mode: • The system will reboot and the configuration is lost. • Default zoning should be off, but here is no check that it is turned off. The configuration is reset. If you have a defined or effective configuration and default zoning is on, when you disable the switch and change to McDATA Open Fabric mode, you will be prompted that all configuration will be lost and that the system will reboot. Responding "yes" you will put the system in McDATA Open Fabric mode with default zoning and safe zoning turned off. Fabric OS Command Reference 277 53-1000599-01
