Frame Redirection

Frame Redirection

Frame Redirection provides a means to redirect traffic flow between a host and a target that use
virtualization and encryption applications, such as the Brocade SAS blade and Brocade Data
Migration Manager (DMM), so that those applications can perform without having to reconfigure
the host and target. You can use this feature if the hosts and targets are not directly attached.
Frame Redirection depends on the wide distribution of the Defined Zone Database. The Defined
Zone Database on Fabric OS switches is pushed out to all other Fabric OS switches in the fabric
that support Frame Redirection. Redirection zones exist only in the defined configuration and
cannot be added to the effective configuration.
NOTE
Fabric OS v7.1.0 is not supported on the Brocade 7600 or Brocade SAS blade. However, this
hardware can run in a pre-Fabric OS v7.1.0 system and attach to a Fabric OS v7.1.0 fabric.
Frame Redirection uses a combination of special frame redirection zones and name server
changes to spoof the mapping of real device WWNs to virtual PIDs.

virtual initiator and the port where the appliance is attached to the target switch is the virtual target.

NOTE
Frame redirect zones are not supported with D or I initiator target zones.
Use the following procedure to create a frame redirect zone:
1. Connect to the switch and log in using an account with admin permissions.
2. Prior to creating the frame redirect zone, the user has to create a Layer 2 zone for the Initiator
3. Enter the zone
4. Enter the cfgSave command to save the frame redirect zones to the defined configuration.
