FlexAttach Virtual pWWN CFS Distribution

SAN Device Virtualization (SDV)
FC-ID rewrite on the switch indicates a
rewrite-capable switch on the path.
Configuration is distributed. This allows programming
rewrites and connectivity anywhere.
Configuration is secured to device alias.
Does not allow automapping to the secondary device.
FlexAttach Virtual pWWN CFS Distribution
The FlexAttach virtual pWWN configuration is distributed for CFS through IPv4, and is enabled by default.
The FlexAttach virtual pWWN distribution, by default, is on CFS region 201. The CFS region 201 links only
to the NPV-enabled switches. Other CFS features such as syslog is on region 0. Region 0 will be linked
through IPv4 for all NPV switches on the same physical fabric. If CFS has an option to link through IPv4 or
ISL, then CFS will select the ISL path.
Note
NPV switches do not have ISL (E or TE ports) and are linked through IPv4.

Security Settings for FlexAttach Virtual pWWN

Security settings for the FlexAttach virtual pWWN feature are done by port security at the NPV core. Node
WWN of the end device is used to provide physical security.
For more details on enabling port security, refer to the
