Understanding Virtual Fabric restrictions

1

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

In Fabric OS v6.2.0 and later, all commands are subject to additional RBAC enforcement with
regard to Virtual Fabric contexts and switch types. Commands can be executed in one or more of
the contexts described in

Table 2

. Execution of chassis commands requires chassis permissions.

Switch commands are further defined by the switch type restrictions as described in

Table 3

.

Switch type restrictions are not applicable to commands that require chassis permissions.

In a Virtual Fabric environment where contexts are enforced, the following Virtual Fabric restrictions
apply to the RBAC permissions specified in

Table 1

. Refer to userConfig help for more information

on configuring user account access permissions in a Virtual Fabric environment.

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.

Refer to

Appendix A, “Command Availability”

for context and switch type information as it applies to

CLI commands.
