Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 115)

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 v7.2.0 is not supported on the Brocade 7600 or Brocade SAS blade. However, this hardware
can run in a pre-Fabric OS v7.2.0 system and attach to a Fabric OS v7.2.0 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.
FIGURE 9 Single host and target
Figure 9 demonstrates the flow of Frame Redirection traffic. A frame starts at the host with a destination
to the target. The port where the appliance is attached to the host switch acts as the virtual initiator and
the port where the appliance is attached to the target switch is the virtual target.
Creating a frame redirect zone
The first time the zone --rdcreate command is run, the following zone objects are created by default:
• The base zone object, "red_______base".
• The redirect (RD) zone configuration, "r_e_d_i_r_c__fg".
NOTE
Frame redirect zones are not supported with D or I initiator target zones.
ATTENTION
Prior to creating the frame redirect zone, you must create a Layer 2 zone for the Initiator (host) and
Target (storage). This zone must be part of the effective configuration and must be defined using the
port World Wide Name (WWN). Refer to "Creating a zone" on page 350, and "Enabling a zone
configuration" on page 364.
Use the following procedure to create a frame redirect zone.
