Configuring User Accounts and RBAC
If you belong to multiple roles, you can execute a combination of all the commands permitted by these
Note
roles. Access to a command takes priority over being denied access to a command. For example, suppose
a user has RoleA, which denied access to the configuration commands. However, the users also has RoleB,
which has access to the configuration commands. In this case, the users has access to the configuration
commands.

About Rules

The rule is the basic element of a role. A rule defines what operations the role allows the user to perform. You
can apply rules for the following parameters:
• Command—A command or group of commands defined in a regular expression.
• Feature—Commands that apply to a function provided by the Cisco Nexus 5000 Series switch.
• Feature group—Default or user-defined group of features.
These parameters create a hierarchical relationship. The most basic control parameter is the command. The
next control parameter is the feature, which represents all commands associated with the feature. The last
control parameter is the feature group. The feature group combines related features and allows you to easily
manage of the rules.
You can configure up to 256 rules for each role. The user-specified rule number determines the order in which
the rules are applied. Rules are applied in descending order. For example, if a role has three rules, rule 3 is
applied before rule 2, which is applied before rule 1.

About User Role Policies

You can define user role policies to limit the switch resources that the user can access. You can define user
role policies to limit access to interfaces, VLANs and VSANs.
User role policies are constrained by the rules defined for the role. For example, if you define an interface
policy to permit access to specific interfaces, the user will not have access to the interfaces unless you configure
a command rule for the role to permit the interface command.
If a command rule permits access to specific resources (interfaces, VLANs or VSANs), the user is permitted
to access these resources, even if they are not listed in the user role policies associated with that user.
