“The Cisco NX-OS software provides four default user roles:
•network-admin—Complete read-and-write access to the entire NX-OS device (only available in the default VDC)
•network-operator—Complete read access to the entire NX-OS device (only available in the default VDC)
•vdc-admin—Read-and-write access limited to a VDC
•vdc-operator—Read access limited to a VDC”
“Cisco Fabric Services (CFS) allows the NX-OS device distribute the user role configuration to other NX-OS devices in the network. When you enable CFS distribution for a feature on your device, the device belongs to a CFS region containing other devices in the network that you have also enabled for CFS distribution for the feature. CFS distribution for the user role feature is disabled by default. ”
