Role-Based Access Control
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role. 
Users are granted permissions based on their user roles, not on their individual user ID. User roles are 
created for job functions and through those roles they acquire the permissions to perform their 
associated job function.

Overview of RBAC
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role. 
Users are granted permissions based on their user roles, not on their individual user ID. User roles are 
created for job functions and through those roles they acquire the permissions to perform their 
associated job function. Each user can be assigned only a single role. Many users can have the same role.
The Dell Networking OS supports the constrained RBAC model. With a constrained RBAC model, you can 
inherit permissions when you create a new user role, restrict or add commands a user can enter and the 
actions the user can perform. This allows for greater flexibility in assigning permissions for each 
command to each role and as a result, it is easier and much more efficient to administer user rights. If a 
user’s role matches one of the allowed user roles for that command, then command authorization is 
granted.
