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 Cisco MDS 9000 Family NX-OS Security Configuration Guide.

Guidelines and Limitations

Following are recommended guidelines and requirements when deploying FlexAttach virtual pWWN:

•FlexAttach configuration is supported only on NPV switches.

•Cisco Fabric Services (CFS) IP version 4 (IPv4) distribution should be enabled.

•Virtual WWNs should be unique across the fabric.

Automatic assignment of virtual pWWN can be configured on an NPV switch globally, per VSAN, or per port. When assigned automatically, a virtual WWN is generated from the device local switch WWN.

Prerequisites

The port must be in a shut state when the virtual pWWN is enabled.
