Access-level switches
In a typical enterprise network architecture, the access layer switch is the first point of contact between end-user devices and the rest of the network. These switches connect endpoints such as PCs, printers, VoIP phones, and wireless access points, enabling user traffic to. This command produces the boot loader prompt (switch:) after the switch is power cycled. Password type 0 and type 7 are deprecated. Enable levels define what a user can do once logged in to a network device, offering a powerful framework for role-based access control (RBAC).
