Multi-service Frame Redirect
MSFR uses the same approach as Frame Redirection, only the number of host-to-targets is
expanded to support up to seven redirected devices. MSFR zone objects are stored in the Defined
Configuration. The Name Server enforces MSFR devices that are defined through MSFR zoning.
MSFR implementations can co-exist with Frame Redirection in the fabric.
You create MSFR zones in the Effective Configuration to define policies between Hosts and Targets
the same as would be done for a non-MSFR configuration. MSFR zoning objects are visible in the
Defined Configuration. The exception to creation through the API is an MSFR over FCR, which
requires use of the MSFR CLI. The Host and Target edge switches must be running MSFR-capable
firmware Fabric OS v6.3.0.
The default behavior for redirection ordering will be the order in which the zones are created. For
example, if you first create an MSFR zone for Appliance A with Host X and Target Y (first zone
created), then create another MSFR zone for Appliance B with Host X and Target Y (second zone
created), then traffic will flow as follows for traffic from Host X to Target Y traffic:
1. From Host X to the VT of Appliance A.
2. Appliance A processes the frames and forwards them using the VI of Appliance A to the VT
of Appliance B.
3. Appliance B processes the frames and forwards them using the VI of Appliance B to
Target Y.
FIGURE 7 Multiple zones
Traffic will flow as follows from Target Y to Host X traffic:
1. Frames start at Target Y to the VI of Appliance B.
2. Appliance B will process the frames and forward them using the VT of Appliance B to the VI
of Appliance A.
3. Appliance A will process the frames and forward them using the VT of Appliance A to
Host X.
A series is the sequence in which MSFR zones are accessed. The first in the series is the first MSFR
zone you create, the second in the series is the second zone, and so on. You can create a new
MSFR zone and insert it as the first in a series. The default behavior is for a new MSFR zone to be
added last in a series. When the “first” option is specified, the newly created MSFR zone will be
