14 Frame Redirection in interoperable fabrics Frame Redirection in interoperable fabrics Frame Redirection provides a means to redirect traffic flow between a host and a target to virtualization and encryption applications so that those applications can perform without having to reconfigure the host and target. Use this feature if the hosts and targets are not directly attached to M-EOS switches. NOTE For support of Frame Redirection in McDATA Fabric Mode (interopmode 2), M-series products must use M-EOS v9.8 or later. For support of Frame Redirection in McDATA Open Fabric Mode (interopmode 3), M-series products must use M-EOS v9.9 or later. Only the ES-4400, ES-4700, M6140, and Mi10k switches can have devices directly attached that have data encrypted or unencrypted. The Defined Zone Database in McDATA Open Fabric mode supports the special Frame Redirect zones. Frame Redirection supports the following: • Allows you to create Frame Redirection zones and send redirection zone updates to switches running M-EOS in McDATA Open Fabric mode (interopmode 3) and McDATA Fabric mode (Interopmode 2). • Allows redirection of data traffic for hosts and targets attached to switches running M-EOS. • Allows you to create FR zones and distribute the defined database when in McDATA Open Fabric mode (IM3) only. • Allows you to use the Host Offline Re-Key feature for switches running M-EOS. NOTE There are no limitations on fabric configurations other than the normal McDATA Open Fabric mode fabric limitations. Hosts and targets can be both attached to McDATA switches or spread among switches running Fabric OS and switches running M-EOS. For information on frame redirect zones, see in Chapter 4, "Routing Traffic". Traffic Isolation zones in interoperable fabrics The Traffic Isolation feature allows you to control the flow of interswitch traffic by creating a dedicated path for traffic flowing from a specific set of source ports through Fabric OS switches using zones. Traffic isolation (TI) is supported in McDATA Fabric mode on Fabric OS switches only; McDATA Fabric mode is the only mode that supports the Defined Database, which is distributed and synchronized with all Fabric OS switches in a fabric. TI zones within edge fabrics are used to route traffic between real devices and proxy devices to a particular EX_Port. Use the M-EOS Preferred Path method to steer application traffic down a particular path when traversing M-EOS switches. In the case where a Preferred Path goes away, only the ports assigned to that path are re-routed to other paths. When the Preferred Path is re-established, the ports assigned to that path are re-routed back. Use the Prohibit Dynamic Connectivity Mask (PDCM) method for specific forced network control. You must perform this configuration at the director or backbone platform level. For detailed information on creating TI zones, see Chapter 18, "Optimizing Fabric Behavior". 310 Fabric OS Administrator's Guide 53-1001763-01
