New OUI Support on B-series platforms Overview The OUI (Organizationally Unique Identifier) value is part of a Fibre Channel WWN that uniquely identifies the manufacturer of Fibre Channel products. The OUI values assigned to Brocade are used by Fabric OS to validate certain fabric interoperability support. The currently assigned OUI/WWN values are exhausted, necessitating Brocade to use a new OUI value for WWN assignment. The new OUI value for Brocade is 00:05:33. A WWN of 10:00:00:05:33:41:5c:c1, for example, demonstrates the usage of the new OUI. Fabric OS 6.4.x recognizes the new Brocade OUI value to guarantee proper functionality. It is important to note that no switch with the new OUI/WWN should be downgraded to a version of Fabric OS that does not recognize this new OUI (previous to Fabric OS 6.3.1a). It is also important to note that specific minimum requirements for recognition of the new OUI are neither validated nor enforced by Fabric OS. Impact of products with the new OUI to existing fabrics/environments In most situations, a switch that uses the new OUI can be seamlessly added to an existing fabric, even if the other switches in that fabric are not using Fabric OS versions that are aware of the new OUI value.

New OUI Support on B-series platforms
Overview
The OUI (Organizationally Unique Identifier) value is part of a Fibre Channel WWN that uniquely
identifies the manufacturer of Fibre Channel products. The OUI values assigned to Brocade are used
by Fabric OS to validate certain fabric interoperability support.
The currently assigned OUI/WWN values are exhausted, necessitating Brocade to use a new OUI
value for WWN assignment. The new OUI value for Brocade is
00:05:33
. A WWN of
10:00:
00:05:33
:41:5c:c1
, for example, demonstrates the usage of the new OUI.
Fabric OS 6.4.x recognizes the new Brocade OUI value to guarantee proper functionality. It is
important to note that no switch with the new OUI/WWN should be downgraded to a version of
Fabric OS that does not recognize this new OUI (previous to Fabric OS 6.3.1a). It is also important
to note that specific minimum requirements for recognition of the new OUI are neither validated nor
enforced by Fabric OS.
Impact of products with the new OUI to existing fabrics/environments
In most situations, a switch that uses the new OUI can be seamlessly added to an existing fabric, even
if the other switches in that fabric are not using Fabric OS versions that are aware of the new OUI
value. However, there are some exceptions and limitations to consider before adding a switch utilizing
the new OUI to an existing fabric or environment.

Fabrics with encryption products:
If an HP StorageWorks encryption switch or blade using the
new OUI is added to an edge fabric of a Fibre Channel routed fabric, Frame Redirection capab-
ility could be impacted across the FCR backbone, thus impacting the encryption functionality.
Therefore, the FC routers in the FCR backbone fabric need to be upgraded to a firmware version
that supports the new OUI.
•
Interopmode 2 and 3 fabrics:
In an interopmode 2 or 3 fabric with VE ports, the switches on both
ends of the VE link must run a firmware version that supports the new OUI, or the VE ports may
not function correctly, resulting in unpredictable behavior.
