Understanding Virtual Fabric restrictions

Additional command restrictions apply depending on whether Virtual Fabrics or Admin Domains are
enabled in a fabric.
NOTE
Virtual Fabrics and Admin Domains are mutually exclusive and are not supported at the same time on a
switch. To use Admin Domains, you must first disable Virtual Fabrics; to use Virtual Fabrics, you must first
delete all Admin Domains. Use ad --clear -f to remove all Admin Domains. Refer to the Fabric OS
Administrator's Guide for more information.
Understanding Virtual Fabric restrictions
All Fabric OS commands are subject to additional RBAC enforcement with regard to Virtual Fabric

Virtual Fabric contexts
Definition
Command applies to the current logical switch only, or to a specified
logical switch.
Command applies to the chassis on which it is executed.
Command can be executed in a logical switch context or in a chassis
context.
Command is not supported in Virtual Fabric mode.
Switch Types
Definition
Command can be executed in any switch context.
Command can be executed only on the base switch.
Command can be executed only on the default switch.
Command is a chassis command or not supported in Virtual Fabric
mode.
Any given role is allowed to execute all switch commands to which the role is authorized in the
account's home context. The default home context is the default logical fabric FID 128.
You can change an account's home context to a specified FID and configure the account
permissions to access additional logical switches specified in the user's Fabric ID list.
Accounts with user or admin permissions can be granted chassis permissions. A user account with
the chassis role can execute chassis-level commands at the user RBAC access level. An admin
account with the chassis role can execute chassis-level commands at the admin RBAC access
level.
