Understanding Virtual Fabric restrictions

In 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 7. Execution of chassis commands requires chassis permissions.

Switch commands are further defined by the switch type restrictions as described in Table 8.

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 6. 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.
