Cisco Nexus 5500 Series NX-OS - Configuring Static or Preferred Domain Ids

If you change the configured domain ID, the change is only accepted if the new domain ID is included in all
the allowed domain ID lists currently configured in the VSAN. Alternatively, you can also configure
zero-preferred domain ID.
You must enter the fcdomain restart command if you want to apply the configured domain changes to the
runtime domain.
Caution
If you have configured an allow domain ID list, the domain IDs that you add must be in that range for the
VSAN.
