Usage Guidelines
You can use this command to select the principal switch, configure domain ID distribution, reconfigure
the fabric, and allocate FC IDs.
We recommend using the optimize fast-restart option on most fabrics, especially those with a large
number of logical ports (3200 or more), where a logical port is an instance of a physical port in a VSAN.

The following examples show how to configure the Fibre Channel domain feature.
